3D Contour

The Contour strategy is designed to give you an optimal finish for steep regions in your geometry. It is typically applied to areas where the slope exceeds an angle of 30 degrees. The Contour algorithm virtually slices the geometry into horizontal layers. At every layer, the toolpath then machines along the edge of the two-dimensional geometry thus created. You can control the vertical distance between the toolpath layers with the stepdown parameter.

In addition, to traditional Contour cuts at constant depth, HSM Performance Pack supports the so-called spiral Contour, which continuously ramps down along the geometry. This completely removes transition marks from the surface of the final part.

As with all strategies in HSM Performance Pack, Contour is optimized for High Speed Machining by assuring maximum smoothness of the toolpath in particular at sharp corners of the geometry.

Full Control Over all Parameters

You can control exactly in which region of your geometry the Contour strategy should be applied by selecting a range of slope angles. Furthermore, Contour supports rest machining such that you only machine regions which were not machined by previous operations. You can freely configure the lead-in and lead-out moves of the operation. HSM Performance Pack generates lead arcs with optimal smoothness to minimize the tool wear. In addition, both the ramping and linking moves are freely configurable to match your tool, machine and part.
