General Mach Discussion / Re: Wrapper and toolpath view
« on: March 09, 2009, 09:10:01 AM »
Thanks for all your help on this people. I think I'm finally getting the picture.
I hadn't noticed that setting the diameter in the settings page, in addition to making the toolpath display proper, does affect the feed rate for the A axis. Perhaps I didn't have all the settings applied at the same time in the various places.
I have only looked at the tool path display but the speed of X and A now appear about the same. I'll have to see what it actually does on the machine.
So - I presume what Mach is doing when applying the diameter factor, is managing the feed of A by inches per minute based on calculating the circumference of the part in inches rather than applying the feedate number as the usual degrees per minute. Is that what's going on?? Seems so.
This looks more manageable by a single feed rate in the code.
I'll have to try it out on the machine later and see what the movements look like.
Sorry for being so dense on this issue. It was difficult to see how all the pieces fit together.
Very cool !!
