HSMWorks provides a toolpath filleting function, which is useful for avoiding sharp corners in 3D finishing toolpaths. With fillets applied, sharp turns in the toolpath can be reduced so that the CNC control can maintain a higher feed rate and/or prevent overshooting.
The Fillets group and Fillet Radius parameter is located on the
Passes tab between Stock to Leave and Smoothing.
The following screenshots show an example of a Parallel Finishing toolpath using a 10mm ball end mill.
Fillets enabled. Fillet radius is 10mm - twice the tool radius.
Fillets disabled, but the model has fillet geometry features applied.
