Catia Post Processing
Catia Post Processing
(OP)
Just curious as to how other NC programmers are creating their code. At my shop, we use Catia to post aptsource files and then we run that through P-works to create the NC program in G-code format. This is very innefficient and there are numerous problems associated with it.
For instance, Catia sometimes posts a code "INTOF" in its aptsource files which causes bad NC code in arcs using circular interpolation over 180 degrees. Our programs are a mile long, partly due to Feedrate commands being repeated unnecesarily with each retract, approach, and machining moves and due to having to post entire programs point-to-point since I cannot trust p-works' circular interpolation. (Though I post all 5-axis programs point-to-point anyways, I would use g02,g03 in 3 axis machining)
My question is how are most Catia NC programmers creating their NC codes and does Catia's post work cleanly. I program 5-axis SNK's and various 3 axis machines all using Fanuc controls or aptsource files. Thanks for all opinions.
