Hey Guys,
Trying to face mill a 'D' slot feature into an existing bore on a Tsugami Mori sliding head with Fanuc programming. (See attached sketch).
I have the part/stock in the main spindle and my milling cutter in the 'b'axis / sub spindle power tool holder.
I cant work out how to program this, there is no Y axis so having to use essentially a G12.1 function but machine wont read this, neither will it read M233 which according to programing manual is "X1/X2,Z1/Z2 axis recomposition control on).
Obviously to machine this feature i need the C axis on head 1 to be moving at the same time as the X axis on the sub tooling but cant work out how.
Any help or ideas would be very much appreciated.

Thanks.

Your milling code should be in head 2, under the T2323 call. That's the tool you're using, the control will calculate the X2/C1 moves from there.
 
Ah, ok that makes sense, thanks.

If I put the C moves under head 2 will it automatically move the main spindle or do I still need to apply the M233 or whatever code it should be?
