operation time estimate in setup sheet ?

[andy55]

Hi, In my old install of mastercam I got an accurate time estimate for the current operation in the setup sheet.

Now I don't get anything... If I do NCUtils/Backplot mastercam gives me a time estimate but I have the feeling it is way off (too long).

Any ideas on what settings I need to input or change ?

Also, for surface/parallell operations, where is the axis along which the parallell cuts are made defined ?

thanks,

Andy

On parameters tab, machining angle. Defualt is 0 degrees - parallel in X axis. Change to 90/-90 to be parallel in Y. Or by whatever angle you wish.

OK, so by playing around with the feed, plunge and retract rate I am now getting acceptable time estimates with backplot.

One question: what feed does backplot assume for rapids (g0) ? can I set this parameter somewhere ?

thanks,

For backplotting, I think it comes from the post that is active at the time. For setup sheet times, it is definately in the post.

Look for this...
