Using Toolpath Fillets

Enabling fillets on a parallel finishing toolpath will primarily affect corners perpendicular to passes:

Parallel toolpath with fillets, radius = 4.0mm.

HSMWorks allows for creation of smoother toolpaths by filleting the surfaces automatically. This prevents the machine control from slowing down in sharp corners, at the expense of leaving a bit of extra material in these corners.

To use the fillet feature, enable it in the property page, and specify the filleting radius:

The fillets option is available on all surface based 3D strategies, with the exception of Adaptive Clearing, where the minimum cutting radius parameter (as explained in the previous tip) provide a similar feature.

For a contour finishing operation, the fillets vertical corners:

Note, that smoothening in this way will leave more stock than specified by the Radial Stock To Leave and Axial Stock To Leave parameters. Therefore you should never choose a fillet radius larger than necessary, and be aware that you may need to remove the left material with an extra operation using a smaller tool.
