About course

In this course, we'll be taking a look at continuous 4-axis machining, using a semi-finished part that would be very difficult to achieve a good finish on using indexing techniques - a helical screw impeller.

  1. 1Rotary RoughingCutting a helical screw involves using rotary roughing techniques to efficiently mill the veins of a partially machined part. The process includes defining job assignments, setting axial positions, and adjusting parameters for remaining stock and tolerance. Simulation confirms the toolpath's effectiveness, ensuring a smooth operation and a desirable finish for subsequent machining steps.Video lesson
  2. 24D Surface FinishingThis section covers the implementation of a 4D surfacing operation for complex part geometries. It details the selection of a 2mm spherical mill, the definition of machining surfaces and curves, and the use of a morphing strategy to maintain surface curvature. The process concludes with generating and verifying the toolpath across the entire part.Video lesson
  3. 34D Morph DetailingThe finishing process focuses on using the Morph 4D operation for precise control over toolpath direction and conformity on helical veins. Participants select a 2mm spherical mill, define machining surfaces and curves, and generate a toolpath that enhances surface finish. The session concludes with transforming the toolpath to cover all veins, demonstrating techniques for machining complex curved surfaces.Video lesson
