C axis - Axis Substitution

[Ryandavidson]

Hi, 

I have a Doosan DVF5000 and have a ring that overhangs the table and need to drill holes at a PCD of about 600mm while rotating the C axis between holes. The machine travel in x is +250mm -350mm, so i need to to travel in X-. I've tried a few things, but it always want to go X+ and will over travel, if i select holes in the X- direction in mastercam, the C axis just rotates 180 and the head moves X+.

Any ideas?

 

Cheers

Have you tried just drilling one hole and doing a transform rotate operation for the remaining holes?

I've given it a try. Dont see any axis substitution in he transform toolpath so have to do it in the first hole. When i do this, it just rotates C axis 180 and starts at X+ again.

Without a file it is hard to make suggestions.

I've attached a zip2go file.

A few years ago i made a copy of a 4 axis machine and changed the rotary for z centerline. then in axis control you can change to the substitution. 

if you have camplete it easier.
