2D Adaptive Clearing is a milling process that removes the "bulk" of the stock from the raw part and roughs it into a shape that is close to the size of the model. The 2D Adaptive toolpath strategy is commonly referred to as High Speed Machining (HSM).
High Speed Machining involves taking a lighter width of cut (side cut), a longer depth of cut and creating toolpath motion that flows. There are no radical changes in direction on an HSM toolpath. As a default, all toolpath motion is in a climbing cut, rather than a conventional cut. Instead of making right angle moves off of the work piece, Fusion calculates arc motion that blends onto and off of, the part. The result is smooth fluid motion that keeps the machine from jerking between moves. This reduces tool wear and tool breakage, due to the NC paths consistent cut volume.
Benefits of HSM Toolpaths
- Reduced Spindle Load
- Reduced Tool Load
- Better Tool Utilization
- Smoother Machine Motion
- Reduced Machine Wear
- Faster Material Removal Rates
- Shorter Cycle Times
