2026 02 25 Mastercam Unified Toolpath - Stop Cutting the Wall

This uses the Unified Toolpath to discuss the difference between Parallel and Guide mode (surface based vs. Geodesic algorithms from the ModuleWorks toolpaths) The part comes from Emastercam.com: https://www.emastercam.com/forums/top... Other toolpaths & topics discussed are: 2d Area Mill, Surface Extend, tool geometry vs. part geometry. 01:05 Creating a 2d Area Mill - Desired path? 02:14 Side view the shape is a radius(!) with Analyze Dynamic 03:10 Solving the problem - my own constraints - Using the same tool and no additional geometry 03:30 Dissecting the original toolpath 05:20 Regen in new version - seeing the problem why it gouged 06:45 Reset to defaults 07:00 Discussion of the goal of my toolpath & selecting geometry 09:00 Following a curve and getting with Extend Edge Curve 10:00 Margins 11:20 Extend/Trim to adjust cuts 13:00 Tool Axis Control 14:50 Swarf Milling toolpath to finish walls 16:00 Geodesic toolpath using Guides and solving the following the curve issue 18:00 Geodesic extend open input curves and how to extend the mesh in the background 19:30 Guide Curves behaving 21:00 Guide vs Parallel and Reverse Cut Order
