回复: 【转帖】TP measurement - can someone explain this to me?

OK, lets see, in the instance you posted, that IS how it works out:

2 X SQRT(.599^2+.017^2) = 1.1984

and when rounding to 3 places, 1.198 so it is correct

Idea #2: are the correct axis being disp…

回复: 【转帖】runoutx2 = concentricity right?

got this from GDT GUYS fourm (aerospace)

Concentricity is categorized as a tolerance of location, not form. However, surface variations of the controlled diameter can have a direct impact on the en…

回复: 【转帖】Runout conflict

haven't we concluded that using the CMM to check runout isn't your best option?

You are correct......both runout and concentricity are dynamic (rotational) checks. The CMM checks parts staticall…

回复: 【转帖】Runout conflict

If you are using runout as your dimension, then what you are seeing is the form error (roundness) factored in with the amount of position error of the first feature selected (no form error is figure…

回复: 【转帖】Runout conflict

It has to do with the LENGTH of the feature and which one is datum. You should be getting the lowest results when using the LONGEST feature as the datum. Think of it this way....

This example will …

【转帖】Runout conflict

Runout conflict
When measuring runout of 2 concentric circles I get 2 different numbers depending on which circle I put in first. When I enter the inside circle to the outside circle I get .0019. W…

回复: 【转帖】runoutx2 = concentricity right?

Concentricity:

The first feature must be a sphere (3D concentricity) or a slot, cylinder, cone, or circle
(2D concentricity). The second feature is used as a datum feature and must be a
cylinder, c…

【转帖】runoutx2 = concentricity right?

Roughly speaking: runoutx2 = concentricity right?


Example. round part. I am chucking on the OD checking the runout of the ID

I get .0008 so the concent. roughly .0015?

PCDMIS软件与DATAPAGE关系

Q: PCDMIS软件与DATAPAGE关系
A: 1、PCDMIS软件为基本测量软件;
2、DATAPAGE为统计分析软件;
3、二者为独立的软件,PCDMIS软件本身不包含统计分析功能,它将测量数据传输到DATA…

为什么安装完pc-dmis后,打开联机程序后,接口选项只有脱机而没有联机的选项呢??请教!!!

你的情况可能的原因如下:
1、已经打开过一个零件程序了;
2、一个pcdmis进程未关闭,又打开了现在这个PC-DMIS窗口;
解决办法:
在“任务管理器”里结束该进程后,重新打开PC-DMIS软件即可。
