Block 20 defines the finish tool which a 1/4” diameter. Finishing
could be done with the same tool but for illustration purposes a
different tool is used.
Block 21 re-defines the island for the side-finish tool. This is
necessary for the finish cycle to work properly
Block 22 is the side-finish cycle. Note that it allows leaving stock
thus permitting multiple finish passes to be taken each with
different tool (if needed).
Block 23 re-defines the island for the bottom-finish tool. This is
necessary for the finish cycle to work properly.
Block 24 is the bottom-finish cycle. The bottom finish cycle will
remove bottom and side stock. If a bottom finish cycle is used first
it may not be necessary to use a side-finish cycle. They are both
used in this example for illustration purposes.
On the previous page is the rendering of the program after being ran
in Draw. The top view is the line draw, and the bottom view is the 3D
solid model.
Approximate machining time is 30 minutes.
