Life Expectancy of a new PH10M and a refurbished one
新的和修復(fù)后的 PH10 M 的平均壽命?

What is it? I replaced my PH10M with a RBE 3 years ago. Now I need to replace it again. What gives?
什么,？我 3 年前從 RBE 更換我的 PH10 M ,。現(xiàn)在我需要再次更換它,。什么原因,？

couple factors influence the life expectancy of a PH9/10 probe head.

Crashes, probe indexing frequency and the power being supplied to the controller. I have seen some PH9's last a good 10 years+ and others go 3 years because they get abused. Are you sure it's the probe head that is buggered and not the internal head cable in your machine?

一些因素影響 PH9/ph10 測頭的平均壽命,。

撞擊,，使用頻率和測量時力度,。我曾經(jīng)見到一些 PH9 正常工作10 多年,而另外一些不足3年因?yàn)樗麄儧]有被正確使用你確定它是測頭故障而不是機(jī)器內(nèi)部的電纜？

Yes, it's the head. I took the head off the column, checked all my connections. What was happening, at 90,0, while measuring as point in the -Y direction, the head would unseat. At first I thought it was the TP200 or module. I put in another TP200 and module, and it unseated again at 90,0. This machine has been running roughly 18 hours a day measuring the same part. It has not seen a crash ever (to the best of my knowledge).

Just got an RBE this morning. It now works as it should.

是的,，是測頭,。我從立柱上拆掉了測頭，檢查我所有的連接,。故障狀態(tài)是:在 90,0角度時, 在－Y方向測量點(diǎn)的時候,，測頭不能抬起。起先,，我認(rèn)為故障的是TP200 或模塊,。我換上另外的TP200 和模塊，在 90,0角度時,它同樣不能就位. 這部機(jī)器一天大概18小時測量相同的零件,。它還不有發(fā)生一次的猛烈撞擊,。（據(jù)我說知）

僅僅是今天早晨換了一個測頭從RBE.它現(xiàn)在正常工作。

從測頭這塊開始翻譯,爭取每天翻譯一點(diǎn)........

I'm looking into the Renishaw SP25. I understand this has good qualities when it comes to scanning. I do a fair amount of scanning. However, I'm not sure about the calibration cycle, and time. I'm referring to the time required to qualify a styli change, and new A-B angles.

I'd like hear from anyone already using the SP25, on any system.

我正在考察 Renishaw SP25 ,。我知道當(dāng)掃描的時候它有很好的特征,。我要做一定量的掃描。然而,，我不能確認(rèn)校準(zhǔn)周期和時間,。我指的校準(zhǔn)周期是探針值變化和使用新的AB角度。

我想要聽些已經(jīng)使用 SP25的人意見, 不管任何系統(tǒng)上
,。
You might refer to this. It is pretty time consuming. Maybe 10-20 times longer that a traditional trigger probe?? Just a guess on that.
http://pcdmisforum.com/showpost.php?p=19575&postcount=1

你可能會涉及這,。時間是相當(dāng)長�,？赡芤粋€傳統(tǒng)的接觸測頭的10-20倍長,？只是在那上的一個猜測。
http://pcdmisforum.com/showpost.php?p=19575&postcount=1

Yes the calibration of the SP25M is time consuming, about 4 mins per probe due to the fact it repeats the routine twice to determine the scanning probe factors. I am very impressed with the probes accuracy on my Mitutoyo Crysta.

是的 SP25 M 的校準(zhǔn)是非常耗費(fèi)時間的,，大約 4 分鐘每一探頭角度,事實(shí)上它重復(fù)常規(guī)的兩次來確定掃描探針.在Mitutoyo Crysta 上其精度給我留下深刻的印象,。

I am using SP25M with Mcosmos, the accuracy is very good but the time difference is as previously suggested - 15/20 seconds per probe position touch trigger, 4:30 - 5 mins per position scanning factors.
The scanning times can be changed but the setting used depends on the accuracy req'd

However,I do not find the calibration time a problem as I use the scheduler in the software to run the program lights out during sunday.

The cmm should be verified in accordance with the following spec'n :-

"ISO 10360-4:2000
Acceptance and reverification tests for coordinate measuring machines Part 4: CMMs used in scanning measuring mode"

我正在使用SP25M和Mcosmos(三豐軟件) ，精度非常好,，但是時間不同意上面兩位:15/20倍常規(guī)接觸測頭,4-5分一個測頭角度 ,。掃描時間是可以改變的，但是使用設(shè)定取決于精度

然而,，我并沒發(fā)現(xiàn)校準(zhǔn)時間是一個問題,我使用軟件中的程序直到周末關(guān)燈為止,。

cmm 應(yīng)該符合下列的標(biāo)準(zhǔn)
ISO 10360-4:2000
三坐標(biāo)認(rèn)可和校驗(yàn)測試4: CMMs中使用掃描測頭”

With the latest release of the Renishaw scanning calibration DLL, Renishaw have reduced the scanning probe calibration times by 35% Using a calibration speed of 20mm/sec, it is now possible to calibrate and qualify a tip in 2 minutes.
The added benifits of an SP25 are probe lengths of 400mm and the capacity to collect so much more information about the part's shape as well as size.

Renishaw掃描校準(zhǔn)最新的新聞鏈接， Renishaw在使用校準(zhǔn)速度在20mm／sec的前提下,已經(jīng)減少校準(zhǔn)時間35%,比較可能的是校準(zhǔn)同時通過一個角度需要2分鐘
SP25 的附加桿最大為400 毫米和更多的能力收集零件外形,。

決定性的
If you are worried about the time it takes to calibrate the probes the easiest thing to do is generate a probe cal routine in MCOSMOS and run on the weekend. It's easy!

如果你擔(dān)憂校準(zhǔn)測頭的時間,最簡單的就是在周末在MCOSMOS中調(diào)用測頭并運(yùn)行.非常容易,！

does probe ball dia affects the measurent?because i have a probe with 2 mm dia and its giving 3 microns error but as i use the 6 mm ball dia probe , the error goes to 10 microns (its stem length is also bigger than the previous probe).
billabong
標(biāo)準(zhǔn)球直徑是否影響測量,？因?yàn)槲矣?毫米直徑產(chǎn)生了3微米誤差.但是當(dāng)我使用6毫米球形直徑探針，誤差達(dá)到了10個微米,。（探針長度比先前大)

Some things to consider here.
Every probe ball ( stylus ) has some slight deviation from the nominal size.
There is also some pre-travel before the touch trigger probe sends the signal to the controller. How much depends on which touch trigger probe you have (

Renishaw TP2 , TP 20 , TP200 etc ).
As long as you are calibrating them against a CALIBRATED masterball ,
AND you have input the CALIBRATED masterball result ( from the certificate )
into your measuring software, you should not have to worry about a difference
of 7 microns between styli.
Remembering your attempts to calibrate the whole machine with gauge blocks,
I'd be surprised if you have the masterball calibrated. If you do, I stand corrected.

在這里需要考慮部分因素
每個實(shí)際探針與理論值都有一些微小的偏離,。
探針將觸發(fā)信號送到控制器之前，也有一些預(yù)行程,。行程的多少取決于你使用的測頭.（Renishaw TP2,TP20,TP200 及其他）
只要你用標(biāo)準(zhǔn)器標(biāo)準(zhǔn)球來校正他們 ,，
輸入標(biāo)準(zhǔn)球的值（從證書）
打開你的測量軟件，你沒必要擔(dān)憂探針偏差7個微米,。
記得嘗試用標(biāo)準(zhǔn)度塊校正整個的機(jī)器,，
如果你校正標(biāo)準(zhǔn)球,我將會感到驚訝。如果你做了,，我認(rèn)錯,。

You need to get the basics of your machine correct 1st before questioning
any error or any accuracy issues you have.
詢問之前你需要第一時間得到你的機(jī)器的偏差
無論任何錯誤或任何精度偏差。

Yes! the diameter of the tip ball gives an error which is known as "cosine error" see attached file.
I don't know what you are measuring but if you check a gauge block with tip dia. 2/6 it should NOT give you that difference in error!
Click here for Tip_points.pdf

是的,探針標(biāo)準(zhǔn)球給出一個誤差以"cosine error "
我不知道你是怎么測量的,，但是如果你用探針檢查一個量塊.但它不能給你偏差的不同,！
點(diǎn)擊這 Tip_points.pdf

If you're trying to check a 3D cone as a 2D dia at a certain Z level then, yes probe diameter will affect accuracy.
If you're look at roundness of a known round item, say a ring gage, then the size of the tip doesn't matter except that larger diameters tend to not be as round as smaller diameters but this is generally a relatively small difference.
The biggest thing that affects accuracy/repeatability/tri-lobing is the length of the stylus. It's much more complicated but generally speaking, if a 1" long stylus results in .0003 of tri-lobing, a 2" long stylus will be around .0006. The same basic concept applies to articulating probe heads. The longer the distance from the fulcrum to the prope tip, the more variance you will have when indexing the probe head. There are many other factors involved but the probe
length is by far the largest contributor. That is, assuming that cleanliness is under control.

如果你嘗試在其中特定z值平面內(nèi)用一個2維測頭測量一個3D立體圓錐體.那么探針直徑將會影響精度。
如果你是檢查已知項(xiàng)目的圓,，例如環(huán)規(guī),，那么與探針的大小是沒有關(guān)系的.除了一點(diǎn)小的不同,結(jié)果中較大的直徑不容易像較小的直徑一樣的圓。
對精度/重復(fù)度/偏差影響的最大的是探針的長度.這是更多復(fù)雜的,但一般來說,，如果這 1" 長的探針誤差為.0003偏差, 2" 長的探針將會是.0006 左右. 相同道理適用于關(guān)節(jié)臂測頭,。從支點(diǎn)到探針頂端的距離越長，你標(biāo)定的測頭偏差越多,。還牽涉許多其他的因素,，但是探針長度是顯然最大的因素。如果其他因素可控的話

. . and of course that the masterball is
calibrated, with the calibration result
used in the software
Is it calibrated Golden Pine ?.

而且當(dāng)然標(biāo)準(zhǔn)球是校正過的,，校準(zhǔn)結(jié)果已經(jīng)在軟件中用了。

Ofcourse yes.The master ball has dia of 20mm but i have input its value in the software according to the certificate that is 20.002mm.I think i am right.am i?i am measuring ring gage dia with the probe of length more than 3 inches with ball dia 6 mm.In small ring gages , the difference in dias are less but a i move to bigger gages , the difference goes to 10 microns.why its varying gage to gage of different sizes?
Anotehr thing when i auto calibrated this probe , the software has calculated its dia as 5.661,5.471,5.767,5.787 against 6mm .why the measured dia is so small.i think this thing is introducing error in my readings from this probe?Any suggestions plz.
當(dāng)然,。標(biāo)準(zhǔn)球?yàn)?0毫米,，但是根據(jù)證書我在軟件中輸入它數(shù)值為20.002 毫米。我自認(rèn)為是對的.對嗎,？我用一根長度超過 3 英寸球直徑為6毫米的探針測量環(huán)規(guī).在小的環(huán)規(guī)中,，直徑誤差很小.但是一旦我換成一個大點(diǎn)的環(huán)規(guī),偏差能達(dá)到10個微米.為什么不同環(huán)規(guī)之間有差異.
另外，當(dāng)我自動校準(zhǔn)測頭的時候,對于6豪米探針軟件校準(zhǔn)直徑值為5.661,5.471,5.767,5.787,。為什么測量直徑如此小,我猜是不是從測頭中引入的誤差到測量結(jié)果中.那位能給點(diǎn)建議

Are you sure the ring gages are round?
You can verify by printing out a plot of the roundness then rotating the ring gage and running again. If the shape of the plot rotates with the ring gage
then the ring gage is out of round.

If you can get 6 microns with a 3" long probe, you're doing pretty darn good.

你確定環(huán)規(guī)是是圓的嗎,？
你可以通過打印出一個標(biāo)準(zhǔn)圓然后旋轉(zhuǎn)環(huán)規(guī),。如果環(huán)規(guī)外形超出繪制的圓，那么環(huán)規(guī)已經(jīng)不圓了,。
如果你能用一個3" 探針僅偏差6個微米 ,，你做的已經(jīng)非常好了

Actually, I may have misunderstood.

When you say 10 microns, you mean the difference between the actual ring gage diameter and the diameter the cmm measures the ring gage?
This is basically due to the fact that the probe is calibrated on a 3d sphere and is averaged out based on that. If you are more concerned about 2d
calibration, the best way to go is to measure a calibrated ring gage and manually adjust the diameter of the probe to make the ring gage dia check correctly.

Assuming that the software you are running allows you to do that. Unless the software will allow you to calibrate based on a 2d measurement, that would be

easier.

Also, if you do this, you can monitor the roundness readings which can detect problems with the probe system or stylus. Stylus wear, dirt, probe module wear,

實(shí)際上，我可能已經(jīng)誤解,。

當(dāng)你說 10個微米的時候,，你的偏差意思是實(shí)際的環(huán)規(guī)直徑和cmm 測量環(huán)規(guī)直徑？
本質(zhì)上由于探針值是基于在一個3D球體上被校正并平均得出,。如果你更關(guān)心2d校準(zhǔn),最好辦法為測量一個標(biāo)準(zhǔn)的環(huán)規(guī),手動調(diào)整探針的直徑確保環(huán)規(guī)測量值正確,。如果你運(yùn)行的軟件
允許你這樣做。除非軟件將會允許你校正基于2d測量,，那樣的話就要比較容易了,。
同時, 如果你這樣做，你們檢查下影響圓度因?yàn)槟馨l(fā)現(xiàn)測頭系統(tǒng)或探針:探針磨損,污垢,，測頭模塊磨損等等

my software donot allow to compensate the probr dia manually.wat can i do now?
我的軟件還不允許手動補(bǔ)償探針直徑.我現(xiàn)在怎么辦,？

Hi G.P.,

How many points are you taking on the ring gauge ?
Are you setting up the main datum as a cylinder through the gauge, or a plane on top of the gauge ?
What algorithm are you using to calculate the dia ?

嗨 G.P.，
你測量環(huán)規(guī)打了多少點(diǎn),？
你有沒有建議一個圓柱坐標(biāo)系通過環(huán)規(guī)或者在環(huán)規(guī)表面建議一個基準(zhǔn)面
你使用什么運(yùn)算法則來教轉(zhuǎn)探針直徑,？(指外接圓法,內(nèi)接圓法,和最小二乘法等等)

GoldenPine. Don't worry about the probe calibrating smaller than its real diameter, that's normal and understandable. What you do need to worry about is the variation of the "calibrated" diameters of your probe stylus which are HUGE. I've just checked the two 6mm probe on my machine and the variations are from 5.987 - 5.991 for 14 probe orientations (swivel length 93mm) and 5.913-5.922 for 17 orientations (swivel length 138mm). I avoid using the 138mm length probe
unless I absolutely have to and it hasn't been cleaned for a while!

I think you need to get your CMM serviced and calibrated or you are, frankly, wasting your time.

GoldenPine。不要擔(dān)心探針校值小于其真實(shí)值,，那是正常的和可以理解的,。你需要關(guān)注的是你的探針" 校正 " 后的直徑的大小。
我剛剛用兩個6毫米探針在我的機(jī)器實(shí)驗(yàn)了下:從5.987- 5.991為14校正方向（旋轉(zhuǎn)半徑 93 毫米）和17方向（旋轉(zhuǎn)半徑138毫米）5.913-5.922.
我盡量不使用那138毫米探針,除非我唯一適用和它不能被排除
我認(rèn)為你應(yīng)該聯(lián)系CMM服務(wù)工程師來校正或者你來做,，坦白地,，現(xiàn)在你在浪費(fèi)時間。

This guy basically has no experience, and you guys are completely training him over the internet for free, and somewhat awkwardly I might add.

He started out with all kinds of monumentally stupid ideas about calibrating his machine himself, now we can easily see that he can't even properly operate a

cmm talk about programming one.

I've sat buy and read a dozen threads started by him asking about ridiculously basic cmm concepts.

Maybe I would be more receptive if he came in here from the start and said "hey guys, I know absolutely zero about cmm's, but I want to be just like

you...can you help me? Where do I start?" But instead I find myself continually astounded by the questions he is asking. It is so compelling to read just so

that I understand it fully when I get to the inevitable end of this story involving a major rejection and impending bankruptcy of some poor company he works

for.

The only possible outcome I can see is the company he works for ending up in financial ruins as he "programs" a part and their setup adjusts the parts so

that they "look good" on the cmm reports and they ship parts to customers, ultimately destined for rejection or worse failure during operation. I honestly

pray when I read his posts that he doesn't make something like steering or braking components, seat belt retractors.....the list goes on and on.

這一個人基本上沒有經(jīng)驗(yàn),，而你們正在免費(fèi)通過互聯(lián)網(wǎng)完整培訓(xùn)他,，我可能稍微增加點(diǎn)難度。

他從自己校正他的機(jī)器的各種非常愚蠢的主意開始,，現(xiàn)在我們?nèi)菀卓闯鏊粋€甚至不能正確操作cmm的人,。

我做出犧牲,閱讀一堆章節(jié)并被他開始問各種荒謬最基本的cmm 觀念。

可能我應(yīng)該更加接納他剛進(jìn)來就說:我基本對cmm了解為零,但是我成為你那樣...你能幫助我嗎?我從那里開始?但是我發(fā)現(xiàn)自己不停的被問的吃驚.我完全理解,當(dāng)我得到這個故事必

然的包括他工作的公司必然是非常容易被淘汰和即將發(fā)生倒閉

我看他服務(wù)的公司最后的結(jié)果是財務(wù)破產(chǎn)作為他'程序'的一部分他們計劃調(diào)整這部分以便他們在cmm報告中看起來好點(diǎn).他們把這個給客戶.最多被拒絕或者在使用中完全失敗.當(dāng)我

讀他那職位的時候,我真誠的起到他不是做方向盤或者轉(zhuǎn)向制動器,安全帶....這個列表繼續(xù)

I (like many of you) am a professional fault-finder by trade.

Let's see if I can find any errors or problems with anything that Section has stated in his last post.

Nope, can't find a single thing in error. I'd say that he's hit the nail squarely on the head.

In fact, I've wondered several times in the past if this guy was really an experienced CMM geek who's just messin' with our heads, but I'm convinced that

he's on the level, which is quite disturbing. His situation could be used as an excellent case study about why CMM geeks should ALL be certified - JUST LIKE

THE MACHINES HAVE TO BE!!!!

Analogy time: Why shouldn't it be good enough if a VEHICLE is inspected, registered and licensed? Why should the OPERATOR have be trained and licensed? The

car's just fine, and that's the thing that does all the work! The operator just goes along for the ride, right? What could possibly go wrong?
我(象你們中很多人一樣）是一個經(jīng)過專門培訓(xùn)對質(zhì)量吹毛求疵的專業(yè)人士,。
如果我能找任何的錯誤或的問題任何事,，讓我們見到那一個區(qū)段已經(jīng)在他的最后職位中陳述。
不,，不能在錯誤中找一些線索,。我將會說，他腦子壞掉了,。

事實(shí)上,我在過去懷疑過很長時間這個家伙是不是真的是一個有經(jīng)驗(yàn)的cmm怪人,他僅僅是打亂我們的思路,但是我確認(rèn)他是一個卓越的人.這是不用討論的,他的情況應(yīng)該被當(dāng)作一個

類似：如果一輛車輛已經(jīng)被檢查,，登記以及許可,，它為什么不是最佳狀態(tài)？為什么那操作員應(yīng)該被訓(xùn)練而且得到許可的,？小車還好,，所有的工作都一樣！操作員僅僅是湊湊熱鬧

hi,

嗨,，
我認(rèn)為,，你們是從我這郁悶.我真的抱歉。但是還是感激幫助者,。

my machine is measuring a standard ring gage 3 microns less.is there any option in the metrolog to compensate it manually or i have to add up in the results

at the end?
我的機(jī)器測量一個標(biāo)準(zhǔn)環(huán)規(guī)小了3微米.是不是有選項(xiàng)去手動補(bǔ)償或我不得不在最后把它加入到結(jié)果,？

Is that 3um less than nominal, or 3um less than the calibrated result for the gauge ?
3微米是不是小于名義值，或3微米小于環(huán)規(guī)的校準(zhǔn)結(jié)果,？

its the nominal.As its has been engrved on the standard for example 10 mm (+9 microns).cmm is reading it as 10.06 mm.
正常,。如果已經(jīng)被標(biāo)定例如10mm（+9mm）。那么cmm 讀數(shù)為10.06mm,。

10.06 is plus sixty microns. Six microns is .006.

Perhaps you meant 10.006?

Is your cmm nc or manual? If it's manual, my advice would be to give up and buy a real cmm. If it's nc then make sure you have a program to calibrate the

stylus. Make sure the measurements on the masterball are taken properly. Make sure the points are properly spaced and contacting the masterball at the

optimal "attack angle".

Once you have a program for probe calibration then you should do some testing. Calibrate the stylus and inspect the ring gage several times. Re-position the

ring gage between runs. You may want to re-clean it between runs but be careful not to affect the temperature. Then, repeat this whole process several times

(including re-calibrating the stylus). If the variance you see here is more than .003mm (i expect it will be), then the 3 microns you are seeing is noise. If

it's more than .03mm then there's probably something wrong.

If it's somewhere in between and you need better, if possible, try a shorter stylus.

10.06是60個微米,。六個微米是.006 。

可能你認(rèn)為是10.006?
你的cmm是自動還是手動,？如果它是手動,，我的建議是放棄它同時再買臺真正的cmm 。如果它是自動, 那么確信你有建議一個探針校正程序,。確定在標(biāo)準(zhǔn)球上的測量正確的,。確

定點(diǎn)是以正確的位置和最佳的法線角度去接觸標(biāo)準(zhǔn)球.

一旦你有一個校準(zhǔn)測頭的程序,你應(yīng)該做一些測試.校準(zhǔn)探針和檢查環(huán)規(guī)多次。測量中重新調(diào)整環(huán)規(guī)位置,。在測量中你可能想重復(fù)調(diào)整它但是小心不要影響它的溫度

然后,，重復(fù)這整個程序多次（包括重復(fù)校準(zhǔn)探針）如果在這里你見到的差異超過.003mm(我預(yù)計它會）, 那么你看到的這3個微米是噪音。如果它是超過.03mm, 那么那些地方可能

有錯誤,。

如果它處于中間,，同時你想更要的效果.如果可能的，試一個較短的測針,。

Agreed Ken,
The biggest ball dia with the shortest shank length is always the way to go. A TP200 instead of a TP2 or 20 would reduce the lobing effect also, but I

realise the choice is not always there.

I always set my alignment plane through the centerline of the ring ( cylinder measurement ) as , although these gauges are usually square from the cylinder

to the outer surfaces, you just never know for sure.

The other matters to add up are,
the uncertainty of measurement of the machine :
the actual calibration result for the ring gauge ( not the engraved size ):
the algorithm used for the dia result :
room conditions ( temp humidity cleanliness ) :

Good luck G.P. in finding your 3 microns. They're in there somewhere.
同意肯恩，
這個方法最好是用最大的球莖和最短的探針長度,。用TP200代替TP2或tp20會也減小效果,，但是我認(rèn)為問題并不在那里。

我總是通過環(huán)規(guī)的中心設(shè)置我的基準(zhǔn)面(測量圓柱),雖然這些環(huán)規(guī)從圓柱到外圓面是非常一致的,單你僅僅是不確

其他因素加起來是,，
機(jī)器的測量的不確定：
環(huán)規(guī)實(shí)際的校準(zhǔn)結(jié)果（不是被標(biāo)的值）:
結(jié)果圓的運(yùn)算法則：
房間環(huán)境（臨時濕度） :

G.P找到的3微米誤差就在里面,祝你幸運(yùn)!

Is it necessary to align a ring gage beofre the dia measurement.I have read somewhere that we dun need to make alignment for dia measurements.is it right?

在直徑測量之前有必要定位環(huán)規(guī),。我已經(jīng)某處讀我們需要制造對準(zhǔn)直徑測量.是嗎,？

It's only my opinion G.P. , but if your trying to find your 3 microns,

then use all means at your disposal to measure each point perpendicular to the surface.

That includes aligning the ring gauge before measuring for dia.

As a matter of interest, what size does the calibration certificate say the ring gauge is ?
它只是我個人的意見 G.P. ，如果你想嘗試達(dá)到3個微米,，

使用所有的方法(盡力而為),在測量任意一個點(diǎn)都要垂直于表面,。

那包括在測量直徑之前排校準(zhǔn)環(huán)規(guī)。

稍微有點(diǎn)好奇,，環(huán)規(guī)校準(zhǔn)報告說環(huán)規(guī)尺寸是所少,？

I would measure it as a cylinder. Set my coordinate to that cyl. & measure circles incrementally in the ring gage.

我會把它作為一個圓柱來測量。設(shè)定我的坐標(biāo)系為圓柱坐標(biāo)系同時在環(huán)規(guī)中逐漸提高測量圓

You are chasing 3um error in a diameter measurement?!

What type of machine? Manual or CNC
What type of touch probe? TP20, TP2, SP25, TP200
What length is the stylus? 10mm 20mm 100mm
What is the temperature in the room?
What diameter is the ring gauge?

Let's face it... 3um (0.003) is not a significant error, if you have 1 person standing near the machine breathing really heavy and the next day there are 5

people breathing heavy it can effect your measurement.

你試圖測量一個直徑只有3微米的偏差,？,！

哪類機(jī)器？手動或自動
哪類探頭,？TP20,TP2,SP25, TP200
探針長度為多少,？ 20 毫米 10 毫米 100 毫米
房間中，溫度多少,？
環(huán)規(guī)直徑為多少,？

讓我們正視它。3 um（0.003) 并不重要,，如果機(jī)器的附近站立的1個人呼吸真和明天5個人呼吸都能影響你的測量,。

Renishaw styli tip cleaning for probe calibration
為探針校準(zhǔn),清潔Renishaw探針紅寶石球

Obviously before probe calibration, the cal sphere and Styli should be clean and free from debree, which would effect the results of the calibration.
When i first joined my company a simple wipe with the fingers or peice of rag had sufficed.
However I noticed while inpecting the styli under a microscope, the ruby styli was littered with debree such as small peices of aluminium, cast iron, small hairs etc.
Because of this I started to clean the styli and cal sphere with solvent based liquids such as Geneclean, SBP2 & currently Amberklene.
Any thoughts on my process, is a solvent likley to have a detremental effect on the ruby,any alternatives, what do you do at your company?

顯然在探針校準(zhǔn)前,標(biāo)準(zhǔn)球和探針應(yīng)該被清潔,，灰塵有可能導(dǎo)致校準(zhǔn)結(jié)果的偏差。
當(dāng)我剛加入公司的時候,只是簡單的用手或者碎布擦拭就可以了,。
但當(dāng)我在顯微鏡下觀察探針時,，紅寶石探針沾滿灰塵,例如微小的鋁屑,鑄鐵屑，頭發(fā)屑等等
以此我開始用液體溶劑清潔標(biāo)探針和標(biāo)準(zhǔn)球,SBP2或Amberklene,。
在我的理解中,，溶劑有可能對紅寶石產(chǎn)生不良效果，有沒有其他選擇,你的公司怎么做的�,�,？

I generally use a lens cleaning cloth or one of the cloths supplied for cleaning Gauge block sets, although I tend to keep the cloths bespoke for each use ( one for styli only etc ).
我通常使用鏡頭清潔布或者量塊清潔布，盡管我傾向?yàn)槊總€提高一份清潔布,。（為探針專門準(zhǔn)備一個)

Can I convert points of a plane into individual points

我能從多點(diǎn)組成的面中分離出單獨(dú)的點(diǎn)嗎?

I'm sorry, I have not played around to find out for myself due to work load but, I have a disc with 20 pockets, each pocket has 3 recesses. I need to check

the "Z" distance between 2 planes and since I need to referance / align each plane later in the PPG, it would be much easier to pull 1, 5 points out from the

plane and call it an individual point to get my "Z" distance. I can not due a loop due to each point and plane needs a seperate name and for the scientists

to be able to figure out the CMM output easily and at the bottom of each pocket I take 25 pt's so tghey can determin contour of each pocket.

對不起，我不是為了好玩而是真的工作需要,，我有一個圓盤工件,上面分布20個輪廓,，每個輪廓有3個凸行。我需要檢查兩個面之間的z軸距離.在工件坐標(biāo)系中需要整理每一個面,，
這將很容易將 1, 5 點(diǎn)分離出,同時調(diào)出一個單獨(dú)的點(diǎn)坐標(biāo)就可以得到我的z軸距離.我不能得到一個循環(huán)是因?yàn)槊恳粋€點(diǎn)和面都需要一個獨(dú)立的名字.為了cmm更容易的輸出科學(xué)的計

算值.在每個孔的地步我取了25個點(diǎn)以描述每個圓輪廓

--------------------------------------------------------------------------------
why don't you measure as points, then you can connect the sets of points together as planes, but you will still have the points to do any further analysis

with

為什么你不測量點(diǎn)要素,，然后你可以將點(diǎn)云組合成平面，同時你依然擁有點(diǎn)要素做進(jìn)一步的分析

--------------------------------------------------------------------------------
Thanks for the input, I've done that before but just thought I could grab a point of a plane rather than having to manually take my plane points.

謝謝回復(fù),，我已經(jīng)那樣做了, 但是我想能不能從平面上抓一點(diǎn),而不是想手動的測量平面點(diǎn).

--------------------------------------------------------------------------------
If you have measured the plane(s) as auto planes, then you can get hold of the individual measured points using the formula calculation tokens
- for example 'PL[1].MP[1].X' would return the value in X of the first point in plane memory 1. So you could just process a simple loop after the measurement

of each plane to grab hold of the X,Y & Z vals of each point and transfer them into individual element points.
Be aware that the points are uncompensated. I have attempted to attach the example prog (.CAB and ._PI files) which you can import from the part manager
Click here for plane points._PI

如果你已經(jīng)測量平面為自動平面,，那么你能得到一個單獨(dú)的點(diǎn)通過變量計算
－舉例來說 'PL[1].MP[1].X'將會返回平面第一個點(diǎn)的x軸坐標(biāo)值. 因此你僅僅需要做一個簡單的循環(huán)從每一個面的測量結(jié)果中分離出它每一個點(diǎn)的xyz坐標(biāo)值.然后把他們組合成

一個個單獨(dú)的點(diǎn)要素

注意，這些點(diǎn)是沒有探針補(bǔ)償,。我已經(jīng)嘗試附上一個程序例子(.CAB and ._PI files),你可以從程序入口導(dǎo)入
點(diǎn)擊這里為了平面點(diǎn),。＿PI

flyfish - send me your email and I will send the program to you
flyfish －把你的電子郵件發(fā)給我和我把程序發(fā)給你

--------------------------------------------------------------------------------
When you grab the points in formula calculation, you should be able to
also deduct the probe radius result to equate to a compensaed point.

Obviously only if you probed perpendicular to the surface. . . I think .

當(dāng)你抓取測量點(diǎn)的時候，你同樣能夠到也減去探針半徑值得到一個無補(bǔ)償點(diǎn),。

當(dāng)然如果你的探針運(yùn)動軌跡垂直與工件表面... 我個人看法,。

翻譯溫澤英文網(wǎng)站上,三坐標(biāo)發(fā)展歷史
-------------------------------------------------------
istory of CMM
三坐標(biāo)的歷史
The Coordinate Measuring Machine first appeared in the early 60's and the Coordinate-Measuring-Machine industry was immediately born. The earliest Coordinate Measuring Machine was a 3D devices with a simple DRO displaying the XYZ position of the X Y Z Machine.
三坐標(biāo)測量機(jī)最早誕生于60年代,同時測量機(jī)工業(yè)也馬上誕生.最早的三坐標(biāo)測量機(jī)是一個有著三軸驅(qū)動和簡單命令顯示xyz坐標(biāo)值的機(jī)器

There has been much dispute over the years concerning the original inventor of the Co-ordinate Measuring Machine, which has been abbreviated to CMM or CMM's over the years; the nomenclature CMM Machine has now become the industry standard term for 3D Measuring Machines. The first CMM Devices were probably introduced by the Italian company DEA (Digital Electronic Automation Spa) which introduced a Portal Frame CMM with Hard Probe, shortly after Ferranti Metrology from Scotland introduced its Cantilever CMM with D R O and Fixed Probes. DEA introduced their C.M.M. just a few months prior to Ferranti. Ferranti (now International Metrology Systems or IMS ) probably introduced the first DCC CMM (Direct Computer Assist) while DEA claim to have introduced the first CNC CMM. LK Tool, also from the UK have long claimed to produce the first Bridge CMM that has become the standard configuration for CMM Machines in past years. Cantilever CMM, Bridge CMM, Gantry CMM, Horizontal Arm CMM, Portal CMM, Moving Table CMM, Fixed Bridge CMM and Articulated Arm CMM have all become other common configurations for CMMs. The C.M.M. industry today produces over 6000 CMMs annually; C.M.M's come either as a Manual CMM where the CMM Operator manually guides the ManualCMM around the part to undertake CMM Inspection or as a CNC CMM where the CMM is driven automatically from the CMM Part Program.
關(guān)于三坐標(biāo)的發(fā)明者現(xiàn)在有很多的爭論.三坐標(biāo)已經(jīng)被縮寫到 CMM 或CMM's已經(jīng)有些年頭了.這個命名為cmm的機(jī)械已經(jīng)成為工業(yè)上3d測量的標(biāo)準(zhǔn).第一個三坐標(biāo)設(shè)備可能是意大利的DEA(Digital Electronic Automation Spa 數(shù)顯電子自動設(shè)備)公司生產(chǎn).因?yàn)樗a(chǎn)一個擁有硬測頭的龍門式三坐標(biāo).不久 Ferranti (now International Metrology Systems or IMS 現(xiàn)在的國際計量系統(tǒng)公司IMS)可能生產(chǎn)了第一臺顯示式三坐標(biāo)(計算機(jī)協(xié)助)同時DEA公司聲稱生產(chǎn)了第一臺自動懸臂式三坐標(biāo).英國的LK公司很早就聲稱身產(chǎn)了第一臺橋式三坐標(biāo).在過去的一段時間里,橋式三坐標(biāo)變成了標(biāo)準(zhǔn)三坐標(biāo)的結(jié)構(gòu).懸臂式,橋式,臺架式,水平臂式.接口三坐標(biāo),臺面移動三坐標(biāo),固定橋式三坐標(biāo)和關(guān)機(jī)式三坐標(biāo)已經(jīng)全部變成通用三坐標(biāo)結(jié)構(gòu).三坐標(biāo)行業(yè)每年生產(chǎn)超過6000臺；分為手動三坐標(biāo),操作員用手動測量檢驗(yàn)或者自動三坐標(biāo),根據(jù)三坐標(biāo)程序自動驅(qū)動運(yùn)行. C.M.M,。
Each industrialized country of the world has created a domestic CMM Industry. The largest proliferation of CMM Companies have come from the UK. Ferranti Metrology started the UK CMM Industry and licensed their technology to Bendix Corporation in the U.S after a short period where Bendix acted as CMM Sales Agents in the US for the Ferranti CMM. Bendix CMM became the dominant CMM Supplier with its Cordax CMM during the 60's and 70' later becoming known as the Sheffield CMM or Sheffield Company. The Cordax CMM was primarily a Cantilever Style Manual CMM with Hard Probes migrating to Touch Probes from Renishaw as the technology became available. DCC CMMs from Cordax and Sheffield also became popular as computers entered the field of CMM Metrology.
世界上每一個工業(yè)化工業(yè)都產(chǎn)生了本國的三坐標(biāo)設(shè)備廠,最大的拓展的公司來自英國. Ferranti開始生產(chǎn)英國三坐標(biāo)設(shè)備,同時授權(quán)他們技術(shù)到美國Bendix公司.短期內(nèi)Bendix公司就作為美國一家Ferranti三坐標(biāo)銷售代理公司.在60年代到70年代末Bendix公司變成了一個優(yōu)勢的三坐標(biāo)供應(yīng)商.其產(chǎn)品為Corda三坐標(biāo).Bendix公司就是后來知名的Sheffield公司Cordax CMM是首先將采用從Renishaw公司采購的垂直硬探針的三坐標(biāo)成為現(xiàn)實(shí),Cordax and Sheffield同樣將計算機(jī)作為顯示設(shè)備引入三坐標(biāo)技術(shù)
IMS machines include the Impact CMM, Merlin CMM, and the Umpire CMM a flexible shop-floor gage. LK CMMs are the G80 CMM, G90 CMM, G80C CMM, G90C CMM and use LK DMIS or Cameo CMM software.
