  3. the thumb picture did not show the slot frame line clearly, so I attached another one in which I draw the slot section lines, now you can see the slot side surfaces are tapered, not parallel. thanks Eric
  4. thank you Columbo! the parallel issue, please see the attached picture. no chamfer, I got it, I chosen a 120deg spotdrill instead of a 90deg chamfer. adjust the precision to the highest, the finish still not smooth. see the attached picture. but in Dwain Dyer's file, the verification finish is very smooth, even the precision setup in the middle. the link is Dwain Dyer's video and post. http://www.emastercam.com/board/index.php?showtopic=77157 thanks again Eric
  5. Hi, there, I follow Dwain Dyer's method to practice rotary peel mill. I build a solid model in soildworks, then opened it in Mastercam7, Xform-Roll it at 270deg with a dia of 50mm, then do the peel slot toolpath. the problem is below: the slot the not "parallel", instead with a angle in the verification. no chamfer appear on the verification the finish is not as smooth as I did with Dwain Dyer's file. can anyone tell me what the problems are? how to do it right? thanks in advance.
