Little help from mazak users using EIA/ISO programing

[ntcnc]

Hello all

I have been a member for many years I can usually search and find what I am looking for but couldn't this time so here is my first post!

I am trying to help out a nearby shop that purchased a Mazak V-20. It is a 1985 vintage with the M-2 control. They bought it to run somewhat complicated casting on it. They have asked me to help program and get them going. I have not been on a Mazak for almost 10 years and would rather program on Mastercam than Mazatrol. I am writing a post for Mastercam and would like a little info from some users. This is what I need. Basically it is so I can get the tool changes right.

How is the tool changes called out? from what I seen in the manuals they gave me Txxx and M06 can not be called in the same block. How do you set up next tool? Can I use G91 G28 Z0. call before the tool change? Do I need to send X and Y too?

This is the way I was setting up but would like to verify before I run on machine

(First tool change)
T10
G91 G28 Z0.
M06
T11 (next tool)

(all other tool changes)
G91 G28 Z0.
M06
T12 (next tool)

Any input would be appreciated.

Thanks

Jerry

Some machines need to load the tool into the "Pod" first. Although I can't be positive I would try calling up the tool first.

T#(should get tool ready in changer)

Then M6 to perform the change.

You should then be able to call up the next tool to be used later in the program.

The G91 G28 Z0 may not be the tool change position either.

Below are two examples for M+ or M32, M2 should be similar. First one uses G28 second one uses G30. Sometimes M06 needs to be on the same line others it is on a separate line. Try them until you find one that works. (note: these programs are for using Mazatrol Tool Data for offsets! no G43 D-H is used)

M06 (TOOL CHANGE)
G00 G90 G55 X? Y? M03 S????(POSITION TOOL TO START OP)
