MAZAK LIVE TOOLING WOES

[PODDNO]

GOT A MAZAK 250 WITH Y AXIS, PROGRAMING WITH X6 WHEN I USE LIVE TOOLING AND GO TO TURNING AGAIN IT SEEM LIKE ITS KEEPING TO LIVE TOOL OFFSET. CAN RESET AND REMODLE RESTART WORKS FINE.

DON'T KNOW IF POST IS LEAVING SOMETHING OUT OR MACHINE PROBLEMS.

Look for the Cancel Calls at the end of the cycle. Are they T010000 for say tool 1 and such and are the correct G and M codes being called to end the cycle?

AT THE END OF THE MILLIING CYLCE IT HAS G30 U0. V0. H0. M205 AND AT THE START OF TURN CYCLE IT HAS G53.1 T1212 G18 G99 M202 G97 S1000 M3 R1

ONLY TIME I HAVE THIS PROBLEM IS IF I DO TURNING AFTER MILLING, IF I CAN DO ALL THE MILLING AT THE END OF PROGRAM AND READS THE M30 WORKS FINE.

Okay well the post needs to have the correct codes called to active the turning cycles when doing the turning and life you be good. No book in front of me right now. Who provided you with the post?

I believe inhouse is the name of the supplier of our post.

Okay then it should handle that machine nicely. Have you been in touch with your dealer with your specific problems? Can you post up sample code of what you are getting and what you need? Got a screen shot of your Misc real for milling and for turning?

I'm having a hard time understanding but it seems as though you don't have a "Y" shift after tool change, without one you won't pick up the offset.

G18 G99

M202

G97 S1000 M3

G54

G0 Y0.

using a G30 U0 V0 H0 M205 SEEM LIKE THE Y AXIS IS GOING TO HOME.

This is an offset cancellation problem.

 

Try using a G28 instead of the G30 for the Y (V).

G30 is the Second Reference Return Point.

 

Make sure you are explicitly cancelling the live tool offset and not depending upon the G28/G30 to do it.

This is a shot in the dark but M212 to unclamp the "C" axis. Its been a long time but I think thats what solved the problem for me.

[crazy^millman]

I think the M211 and M311 might also help using the brake. Unless doing indexing then the M210 and M310 might come into play, but that depends on the control. Some controls are more lathe based than mill base and then it become a different set of codes.
