Machine continuously Engages/Disengages Table brake During 5 Axis machining

Anonymous — Wed, 23 Sep 2020 14:39:36 GMT

Hi everyone,

so i'm having an issue where my Haas umc1000ss likes to engages its rotary brakes when the tool moves linear and unlocks when actually making a 5 axis move. It happens every 3 seconds which kills a lot of time and fairly frustrating. I'm wondering if there is a way to eliminate any retract of the tool completely so that the whole time it is running in 5-axis.

Thanks in advance.

I had our reseller write our Haas post so anytime it post out 3+2 it uses the brake. Anytime the program post out as a 5axis toolpath, the brake is turned off at the beginning of the toolpath and back on at the end. It has worked out great for us.

@cory_marty So it isn't something that can be found in the powermill settings? It has to be part of the post processor?

Correct, the post will control all of that. I don't have a good enough understanding of post writing to tell you how to do it though. Maybe someone here has an explanation on how to do it.

We have a POC for any post-processor adjustments we need. I'll add this to the list of changes. Thanks!
