With these last three operations we will have completed the work on the cnc machining center.
This is op 8. All we are doing in this step is to finish cut the curve under the trunion.
OP 9 then goes in and cuts the top of the trunion.
These two pictures shows the top roughed out just prior to the finish pass.
This is how they look after the finish pass.
