Fanuc OT controller

[kantaras]

Anyone using Mastercam ( lathe) to program Fanuc OT model B controller ? Machine requires a secondary tool change position at a given distance from z zero. This controller does not have geometric offsets. So I am between a rock and a hard spot. I do not know how to do this. Mastercam rep. says I will need to purchase a customized post processor. I can not believe I am the only one using this type of machine. (Takisawa TX-2 / Fanuc OT model B controller). Any help would be appreciated.ed help.

I have a post I use for my Fanuc 10t. I can give you a copy. It uses a sub call for every tool change. Different sub call for drill then for turning. So you can put what you want in the two separate programs that are used for the toolchanges. Then just m99 back to the program.

Send me a pm and I will send you a copy.

What Version Of Mastercam?

There are some tool change options on the Toolpath Parameter page that will cvhange the output of the standard MPFan post.

Always help to know what version you have.

On the Toolpath parameter page... Set Home Position to User Defined. You can pick a position if you want.

In Misc. Values. Uncheck the box "Automatically set to Post values...."
Then set Misc Integer #1 to 1 or 0 (you might want to try both).

Regen and rePost the code.

You should get something like this....

(TOOL - 1 OFFSET - 1)
(OD ROUGH RIGHT - 80 DEG. INSERT - CNMG-432)
G0 X10. Y0. Z10.
G0 T0101
G18
G97 S691 M03

Pick Machine Type "Lathe 2X Slant Bed" to get rid of the "Y" axis output.
