2D Adaptive Clearing Strategy

Theoretical Background & HSM Concept

2D Adaptive Clearing is a High-Speed Machining (HSM) roughing strategy designed to clear cavities, pockets, and open profiles. Traditional pocketing toolpaths utilize a constant offset strategy, which inevitably leads to tool overloading in corners and narrow slots. 2D Adaptive Clearing, however, computes toolpaths using dynamic algorithms that maintain a constant tool load and engagement.

The Constant Tool Engagement Angle (TEA)

The core physical parameter controlled by Adaptive Clearing is the Tool Engagement Angle (TEA), also referred to as the contact arc. TEA is the angle formed between the entry point of the cutter into the material and the exit point, measured from the tool center.
