New User here ,
I'm using a 8-axis PMAC machine controller with G/M code gui. I have been using the machine for quite some time indexing into position and static drilling aerospace parts , (5-axis motion) XYZBC rotary tilt
(B) being the 4th axis and (C ) being the 5th axis. My problem is that I have developed a post that is using all 5-axis motion to laser cut a profile
or contour but the controller is treating the radial axis in degrees p/minute and the linear axis in feedrate mode G94 "cutting mode" I need to maintain constant surface speed. When executing just a linear move x,y,z the machine traverses in the programmed feedrate , but when there is a B or C move associated in the same line its feedrate is a fraction of the programmed speed.
Best Regards.
