The Ultimate Undercut Trick in PowerMill | Surface Projection Finishing (Part 1)

Описание: Unlock the ultimate trick for finishing complex, wavy undercut surfaces in PowerMill! In Part 1 of this advanced series, we dive deep into the powerful Surface Projection Finishing strategy. Discover how to machine seemingly impossible features by creating and using a custom "helper surface" designed in PowerShape.

If you've ever struggled to get a clean, consistent toolpath on a non-planar surface with a negative slope, this tutorial is your definitive solution. We'll guide you step-by-step, from designing the driving surface in PowerShape to configuring the perfect, collision-free toolpath for a T-cutter.

➡️ Key Techniques You Will Learn:

The core concept behind the Surface Projection Finishing strategy.

How to design an effective "helper surface" in PowerShape to drive the toolpath.

Step-by-step configuration of the strategy's parameters in PowerMill.

Advanced setup for Leads (Horizontal Arc) and Lead Extensions (Vertical Arc) for safe T-cutter motion.

Why is this method the perfect solution for finishing complex 3D undercuts.
