Mastercam lathe tool producing path flats on curves
I am machine some parts with a number of curves I get small flats not a smooth curve i can see these flats in the Mastercam X4 editor when doing a pre run in mastercam so the program is generating them how do i reduce the size of the flats ?
I have been into configuration but have not found any thing that makes a difference
Regards Ray

Re: Mastercam lathe tool producing path flats on curves
Hi
Thanks I am using spline and not sure if I can use arc I will give it a try tomorrow
What I would like it to be able to control the amount of flats it generates to make the spline I know this will make a lot more G Code but that ok there s only 1 spline but I need it to be smooth
there should be a tolerance setting in each toolpath op.Originally Posted by gtrxu1
.... lower number = smaller deviation from the spline (smaller flats)
nc code will still be point-to-point (no arcs except for cutter comp around the line segments )
Re: Mastercam lathe tool producing path flats on curves
make the Tolerance .001 (not .0001 it wont be needed with this method)
Turn on Arc Filtering
Push the slider to the right and make the arc to line %$ 30 - 5 %.
Make sure arcs are on in the G17 plane.
What will happen is you change all those line to line points with arcs and you will probably not see any transitions.
That will give you short code with G3 and G2 - the machine will not hesitate if its old.
er... it's a lathe... G17 is X/Y plane
Rookie mistake, I had mill on the brain. Next post will have a lathe sample pic.

Re: Mastercam lathe tool producing path flats on curves
In Lathe, click on filter on the second tab then create arcs button. Don't make the tolerance to tight unless you really need it. Experiment, but for most cases .001 works awesome.
