Giritharan - Gary's suggestion is excellent. We use the same reference manual as required by our automotive customers. I'm afraid I can't offer any help with the canned cycles. I recommend that you visit this site:
http://www.brownandsharpe.com
or speak with a local Brown & Sharpe rep in your area.
I've attached an ASCII text file that explains how to suspend DCC mode of the CMM while your operators load/reload parts for the GR&R. If you have any questions about the code, don't hesitate to post back or email me direct.
