Mastercam will give you volume of solids If you hit analyze entity, click on the solid for the part or stock, then hit the properties box. Then its just math from there.

you can use the "mill toolpath" drilling as well for face or cross drilling if you have mill license. that has always been my go to, as some of the c axis toolpaths have been iffy in different versions of mcam. you will have to have the proper tool plane and just select the correct rotation type as AHarrison1 suggested. combine with a transform op for hole patterns.

i believe Iscar is also doing some of these tools now.

you might try adding the P480 to each G195 line and see if the machine likes that better

in most fanuc mill turns (mori) that I have been around the feeds in any line with a c axis move command, feed was in degrees per minute, unless using something like G112

under the tolerance tab there is a option to use one way filtering wich i think would probably help, also if your machine has room try using a smaller tolerance value wich should make the facets smaller, but a larger nc file in general

i assume you are talking about a lathe. g50 is normally called before using constant surface feet.

ie:

g50 s2000 = 2000 max rpm

g96 s500 = 500 surface feet

on some fanuc g50 can give unexpected results, like movement of x or z axis. something like a reference retrn. dont remember its been a long time.

David have u tried a transform opp for your drilling toolpath yet? also might try copying your drilling opp and changing the c/t plane for each additional hole. (not fun, but works good.)

on face tools i just set the c/t plane to side then, c/t plane-rotate and rotate it at the correct angle. for cross tools i use a line defining the centerline of hole and set the c/t plane normal to this line. you may need to flip or rotate. just a note in face work: z+ should always be AWAY from the chuck. in cross work: the x+ axis will be TOWARDS chuck end.

on a bolt circle i always used the c and t plane for the first hole then a transform-rotate opp. never could seem to get the c-axis toolpaths to work right. always used mill toolpaths for drilling and milling.

i think u need to use a seperate cplane/tplane for each c rotation. this should force the c rotation. when doing this make sure to check the c plane that z and y are in correct directions according how tool will be aproching part at c rotation

i would make a bachup of your file first. just so you can go back to the way it was. do a search for operation defaults, i think there are more topics on this subj.

if making second opp on same mc file, use: misc ops-stock flip.
