Can I convert points of a plane into individual points

我能從多點組成的面中分離出單獨的點嗎?

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.在工件坐標系中需要整理每一個面，
這將很容易將 1, 5 點分離出,同時調出一個單獨的點坐標就可以得到我的z軸距離.我不能得到一個循環是因為每一個點和面都需要一個獨立的名字.為了cmm更容易的輸出科學的計

算值.在每個孔的地步我取了25個點以描述每個圓輪廓

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

為什么你不測量點要素，然后你可以將點云組合成平面，同時你依然擁有點要素做進一步的分析

--------------------------------------------------------------------------------
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，我已經那樣做了, 但是我想能不能從平面上抓一點,而不是想手動的測量平面點.

--------------------------------------------------------------------------------
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

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

一個個單獨的點要素

注意，這些點是沒有探針補償。我已經嘗試附上一個程序例子(.CAB and ._PI files),你可以從程序入口導入
點擊這里為了平面點。＿PI

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

--------------------------------------------------------------------------------
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 .

當你抓取測量點的時候，你同樣能夠到也減去探針半徑值得到一個無補償點。

當然如果你的探針運動軌跡垂直與工件表面... 我個人看法。

先亂帖吧,等最后整理下,然后再附加上個人觀點可能會更好點

翻譯溫澤英文網站上,三坐標發展歷史
-------------------------------------------------------
istory of CMM
三坐標的歷史
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.
三坐標測量機最早誕生于60年代,同時測量機工業也馬上誕生.最早的三坐標測量機是一個有著三軸驅動和簡單命令顯示xyz坐標值的機器

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.
關于三坐標的發明者現在有很多的爭論.三坐標已經被縮寫到 CMM 或CMM's已經有些年頭了.這個命名為cmm的機械已經成為工業上3d測量的標準.第一個三坐標設備可能是意大利的DEA(Digital Electronic Automation Spa 數顯電子自動設備)公司生產.因為它生產一個擁有硬測頭的龍門式三坐標.不久 Ferranti (now International Metrology Systems or IMS 現在的國際計量系統公司IMS)可能生產了第一臺顯示式三坐標(計算機協助)同時DEA公司聲稱生產了第一臺自動懸臂式三坐標.英國的LK公司很早就聲稱身產了第一臺橋式三坐標.在過去的一段時間里,橋式三坐標變成了標準三坐標的結構.懸臂式,橋式,臺架式,水平臂式.接口三坐標,臺面移動三坐標,固定橋式三坐標和關機式三坐標已經全部變成通用三坐標結構.三坐標行業每年生產超過6000臺；分為手動三坐標,操作員用手動測量檢驗或者自動三坐標,根據三坐標程序自動驅動運行. 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.
世界上每一個工業化工業都產生了本國的三坐標設備廠,最大的拓展的公司來自英國. Ferranti開始生產英國三坐標設備,同時授權他們技術到美國Bendix公司.短期內Bendix公司就作為美國一家Ferranti三坐標銷售代理公司.在60年代到70年代末Bendix公司變成了一個優勢的三坐標供應商.其產品為Corda三坐標.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成為現實,Cordax and Sheffield同樣將計算機作為顯示設備引入三坐標技術
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.
IMS 機器包括以下型號:Impact CMM, Merlin CMM和Umpire CMM (一個有柔性的空間測量)。LK CMMs系列是G80,G90,G80C,G90C和使用 LK DMIS 或Cameo三坐標軟件。
