These iMachining operations perform cutting of the outside shape. An end mill of Ø12.5 mm (0.5") is used. Two chains are defined, with the first being the Stock boundary and the second being the profile around the part. The Stock chain is marked as open, which specifies the tool should start machining from this chain. iRough has a 0.25 mm (0.01") allowance on the wall, and the iFinish operation finishes the profile. Both operations have a -0.63 mm (-0.025") delta depth, so the tool machines deeper than the part.
