This advanced course will introduce you to the latest 5 Axis technology available in Mastercam 2018. The ModuleWorks suite of toolpath utilities gives you unprecedented control over the cut strategy, approaches, retracts, and links within the toolpath itself. We will explore both surface (solid face) and wireframe based toolpaths. We will cover different methods of Tool Axis control, including 11 different tilting strategies. Special attention will be paid to Collision Control, and how multiple methods of Collision Control can be combined. We will explore new Roughing options, including an option for full 5 Axis Roughing, including Zig-Zag Adaptive; a whole new way to increase productivity beyond Dynamic motion. We will also cover the Linking parameters to show how you can precisely control your entry motion, exit motion, and the linking between moves in the cut.

Topics Covered

  1. Surface Patterns
    • Morph between two curves
    • Project curve
    • Parallel to curve
    • Cuts along curve
  2. Cutting Area, Sorting, Surface Quality, and Stepover
  3. Tool Axis Control
    • Tilting Strategies
    • Side Tilt
    • Contact Point Control
  4. Gouge Checking – Multiple methods of collision control, retraction, and tilting
  5. Triangle Mesh Toolpaths – New roughing and finishing paths explained
  6. Swarf Milling – Why there is a 2nd (and “better”) Swarf Toolpath in Mastercam
  7. Multi-Axis Roughing – Finally, an option for full 5 Axis roughing that isn’t just parallel
  8. Convert to 5 Axis – take your favorite 3 Axis path to the next level
