Remachining is not generating toolpaths — Examine your part and make sure there are really regions where the previous tool diameter would not fit. A fillet is specified by its radius and a tool is specified by its diameter.
Calculating the regions takes too long — Use a stock boundary on the
Remachine tab to limit the search for remachining regions or create a separate feature with only the surfaces of interest.
Regions that are exactly the same diameter as the previous tool are being ignored — If there is a region that you would like to remachine that the previous tool exactly fits into it is best to slightly overstate the
Previous
tool diameter to ensure that the region is properly remachined. For example if you have a pocket with a 0.25 radius corner fillet, you should set the
Previous tool diameter to
0.51 inches. The region is larger than necessary, but the remachining boundaries are more predictable. Increasing the overcut percentage can also help with this issue.
