Problem- Trunion table - brake engagement

[flashno]

Hi all,

We have a TR-110 (really small trunion!), and have been successful in working through learning 5-axis positioning setup & programming. We're moving on to 5-axis simultaneous stuff, and are seeing this problem:

The A and/or B axis brakes engage and disengage when cutting a swarfed wall, producing pauses in the cut, not a smooth motion. Our CAM (MasterCAM X2) is not outputting the brake codes (M10 thru M13), rather, the machine (VF-5) is doing this itself whenever the A or B aren't moving for a second or 2.

Any parameters to look at here, maybe to lockout or delay brake engagement when doing 5-axis simultaneous?

Thanks,

Ed

You need to set up your post to output the brake command M codes before and after simultaneous 5 axis movement. For indexing or positional moves just let the control do it for you. This it what we have done and it worked well.

Turn your brakes off. You do not use them when cutting 5 axis simultaneous.

Thanks, Andrew & Mike, as usual, I was looking too deep - a simple brake off code before the toolpath did the trick.
