Rotary Axis WCS incrementing

Recommended Posts

Trying to learn to use our new indexer and having some trouble getting good code. I'm milling 2 wrench flats on a cylinder and trying to use the rotary to spin the part. I have tried several different stratagies in mastercam but i cannot for the life of me get mastercam to output g54 consistently. No matter how i approach the part it is generating a g55 offset for the second flat, like this:

N120 (FLAT 1)

N130 (COMPENSATION TYPE - WEAR COMP)

N140 T1 M06 ( 1/2 FLAT ENDMILL)

N150 (MAX - Z.325)

N160 (MIN - Z.1545)

N170 M08

N180 G00 G17 G90 G54 A0. X.475 Y-.4965 S1000 M03

N190 G43 H1 Z.325

Removed to save space

N260 (FLAT 2)

N270 G00 G90 G55 A-180. X.475 Y-.4965

N280 G43 H1 Z.325

N290 Z.1545

 

I have tried transforming (rotate) around the x axis and using a tool plane (located on the second flat) but both output g55 for the second flat

I am using bone stock mpmaster and mastercam x4 MU3

thanks for your help

Go to your Misc Values page in the first operation

and put a 1 in

"Lock on First WCS"

 

I set this as a default and set it to 1 for ALL operations..

If you post your whole file and its just set in the first OP, the whole file will be OK..

but if its only set in thefirst OP and you post from the middle, you will get burned..

so I make sure its set in all OPs for safety

When using transform click "Maintain Source Operation's" under Work offset numbering.
