As a CMM programmer, I would like to know how long real measurement will last from offline programme. Part program already includes move speed, touch speed, etc all kind of info. So it should also give an estimated time before real execute.
An actual offline timer that can be fine tune for your specific preference would be a nice feature. Wait, everyone has been waiting for years for multiple print commands to work. And they are still waiting. Well at that rate of development, you might be retired before its release. That is if they even do develop it.
Thank you for this request and comments. We are currently reviewing this request, though it is not planned for the 2022.2 or 2023.1 Release. We wil post our proposals here for feedback once ready, Thanks, Neil
This is an eLearning supplemental course to PC-DMIS for CMM 101, with a focus on offline programming. Helpful offline programming tools are explained to simplify and expedite the programming process. Topics covered include: transformations, Clearance Cube, Probe Path Animation, and collision detection.
We are having a company machine 3 impellers for us currently. They use PC-DMIS at this machine shop. Their programmer was able to export all the points throughout the CMM program. He has created a program that has 934 points. The one impeller has 3 blades that curve from top all the way to the bottom base of the impeller and 3 "splitter" blades.
My boss and our lead SQE are adamant that he and I are "apples to apples" when it comes to the points he uses and I use, which is fine. I am just creating a point and copy/pasting XYZ, IJK. Just a lot of ctrl c, ctrl v action....lol! 5604 times!
If I understood him correctly, he won't report each point individually, rather collect them all as a group and it would "in the background" get high/low deviation and he said that it will add those two results together. So it wont do max deviation x2 "profile". I will ask him about this just to re-verify.
-Question #1 What can I do in Calypso to match something like this? I have 19 points pulled into a plane (recall feature points) then selected it in a Profile characteristic and did two results min/max. This result won't be "apples to apples" on a report like my team wants and expects to see. I may need to have the other programmer change what and how his program reports.
-Question #2 (for those who have PC-DMIS knowledge) With myself and the PC-DMIS programmer are using the same inspection fixture, the same alignment points per CAD model points, will this result in these two different CMM software's give the same data? Is it possible for Calypso and PC-DMIS to report the same data, at least within a few tenths? When the most important items needed are present, i.e. fixture, datum scheme, and the same exact points.
When I got to a certain point in the program after copy/pasting the nominal XYZ, IJK the PC-DMIS programmer was able to supply me I decided to create a few characteristics and run the program. This is being ran on my offline seat so what should have happened was to basically populate nominal data. Well, when I did this, I got big deviations on the 3 profile char. I made in the program. I have no idea what is causing this. Then I added a point using Calypso and I got what I would expect, zero deviation. There must be some sort of disconnect from PC-DMIS nominals/vectors and Calypso.
In my humble opinion, by far the biggest influence is the lack of proper design tolerancing. Almost everything I see is more or less incomplete, ambiguous, illogical, or impossible. Yet all vested parties insist on moving forward with dimensional inspections so that they can see "where we're at". And from then on, it's garbage in garbage out. Improper design tolerancing forces the inspection programmer to fill in the missing information, or patch over impossible tasks. Each programmer will interpret and perform this effort differently, leading to a variety of unstable possible outcomes.
