View Full Version : Arcs rather than point to point?

10-31-2010, 10:22 PM
I am machining a bunch of small "pedistals" with rounded edges. When the code is generated it autoamtically does point to point using the Z-Finish, is there any way to make it use arcs?

If I do a 2D Contour and just step it down like I want I get Arcs (i's and j's) which cuts nice, unlike the point to point, let alone the over all size of the program.

You can use the Arc Filter in the operation manager - but I don't trust it. The new V5.1 has new tool path engines for Z finish and there is an integrated Arcfilter. Although I haven't used them enough to trust them yet

I use a surface tolerance of .0001-.0002" for my finishing toolpaths and just live with large programs.

I have the same setup Motion Master 5 axis Router with Fagor 8050 controller.

I use the arc filter option when I post but sometimes when the circles require the machine to be in G18 XZ or G19 YZ circular plane the 8050 control generates errors. I never tried to figure out what the errors mean, so I only use it in G17 XY circlular mode.

The larger error tolerance that you set the smaller the program is, use the largest setting that you can get away with...
