Transform/Rotate off-center form

I have a part that has a partial gear form that’s off-center from the back end that’s chucked on the indexing head (X+). I can’t figure out how to cut one tooth and transform/rotate for the rest of the teeth. With a gear form that’s on-center I can make a new WCS for the first tooth to rotate it to the top. On the operation I change the WCS to top and leave the tool plane and construction plane to the new WCS. I transform the operations to cut the rest of the teeth using left side for the rotation view. On this part with the gear form off-center I changed the center point on transform/rotate to the center of the gear form and the toolpath looks correct but when its posted the Z depths don’t change. I’ve tried several combinations but I’m not having any luck. Anyone have an idea how to get it to post right? Can Mastercam X7 do this without programing each tooth or holding the part off-center? If it can’t be done I will have to chuck on the off-center ID because we don’t have a 4 jaw and that’s going to take a lot longer to rough the rest of the part.

 

Thanks!

Jeff

J you need to use Coordiante as the method and check include origin and then it should produce the results you are after.

Yes I missed that and I did not see where you were using the T-C Plane with a shifted Value. What you have done is negated the point you picked in the Transform operation by using one in the T-C Plane that is the same place. The T-C Plane need to use the Origin then you pick the place in the transform where you want the rotations to come from. By making them the same you tell Mastercam they are the same place and then you would not see a changed value. I missed you wanted the index as well, so here is the file fixed and the posted code so you can see now it is doing everything you would expect. I also changed your depth to incermental since you had the absoulte vlaue it would be wrong

NP Crazy^Millman...I stripped the file so I could upload it to get across what I was trying to do...its 20 MB.

 

Its taking me a bit to wrap my head around this with cutting using a WCS that's not on the rotation axis. I have to go back to the original file with the solid and see if I can get the same results with roughing and surfacing the teeth. SO...I create the toolpaths using the offset WCS that puts the tooth on top, change the WCS to top in all 3 places in the operations, Transform/Rotate the toolpaths using the left side and center of the gear form...
