Hey y'all, I'm an untrained inexperienced PC-DMIS user. I started learning on my own a week and a half ago at the request of my boss at my internship for GE. I am working on a OPTIV optical CMM. We are measuring several radii on notches on the part as well as angles and distances for chamfers.
I am having a tough time with repeatability for some of these radii. There are two in particular that have a 30 degree arc to measure from and a 40 degree arc to measure from. This is too small to be reliable with my current method. Originally it just took the measurements and printed the report. Now, I inserted IF statements if OUTTOL <> 0 etc. in order to rerun that peice of the program. Even still I am hoping there is a better way to assure accuracy in this case. Maybe a combination of runs and then create a radius of best fit? Any ideas are welcome!
I hope I provided enough information. Also thanks to everyone who has posted so much useful information on other posts that have helped advance my learning curve. Also I have to use my office computer as the shop computer(with PC-DMIS) is not connected to the internet. So it is not convenient for me to copy and paste my own code.
