How to calibrate HAAS TRT without calling HAAS?

We had an insert tool blow up while running a part on the TRT. It seems that our DWO is now off from the test run we did. We machined a square part and cut a slot .01 deep on at A0 C0, C90, C180, and C270. It was .06 deep on one side , and barely touched on another.

Anyone have a way of calibrating the HAAS TRT without calling HAAS for a repair?

byulax, your thread title will get more responses if you edit it (go to "Advanced" to do so) to more accurately say "How to calibrate HAAS TRT without calling HAAS?".

Good luck, sounds like the machine took quite a hit.

Sounds like you shifted the trunnion on the table. You'll need to realign it and re-find your center of rotation.

first, if the hit was hard enough, inspect the casting for cracks, then check for straightness of the rotary along a machined surface.

If those two are fine, then put the rotary axes at B0 C0 and check tram of the platen with a test indicator.

If it's off, adjust the position to indicate 0, and then in settings -> rotary, you'll need to set the tool change offset for each axis of the active rotary (F2, i think) Re-zero the axes.

Also, you'll need to check the MRZP location using VPS. It's pretty self-explanitory with the prompts. call up the probe (make sure the probe is calibrated and running true, of course), and I think the trunnions have a fancy quick-check where it checks the center bore, and then rotates the tilt axis 90 degrees and checks another point.

This should pass some values to the macros tab (10120 or 10150 or so). write these down. go back to settings, and compare your new values to the ones already in the settings. Populate these values into the MRZP settings (354-356?). It might use master / slave values, in which case it's the next set of values down.
