Title: How to set up Mach3 so that B Axis controls rotation of the mill head
Post by: DonV on January 04, 2015, 03:59:39 PM

Hi all,
  I'm new to Mach 3.
  I'm trying to set up the program so that the program understands that "B" axis controls partial rotation of the milling head through 120 degrees (30 degrees CW and 90 degrees CCW), instead of controlling a rotary table that rotates the part to be machined along the B axis.  How do I do that so that the center of rotation is correct while also getting machine tool length compensation adjusted for etc.?
  Is this something I should be trying to solve in Mach3? in the SmoothStepper motion controller? or in whatever CAM program I am using to generate G code?

Respectfully,
DonV

Mach3 does not do kenematics so you do NOT have world point jogging of the B axis. As to the setup to generate Gcode that would be UP TO the CAM program You would have to have a 4/5 axis CAM and setup the axis offset there so it KNOWS how to generate the proper geometry for the part and tool  offsetting.

Just a thought, (;-) TP
