AutoCAD Training Overview
In NC Milling, users learn the techniques involved in the creation of NC Operations using up to 3-axis milling machines. This hands-on course contains extensive practice exercises to provide users with real-world experience in creating NC manufacturing models. This course takes users from the initial steps of setting up the manufacturing environment to the end goal of producing G-code.
AutoCAD Training Topics
- Creation of the manufacturing assembly
- Definition of the operation and workcell components
- Definition of mill volumes, windows and surfaces
- Tool setup
- Logical procedure for creating NC sequences for hole making, facing, volume, local, pocket, profile, trajectory and surface geometry
- Toolpath verification
- Duplication of toolpaths
- Generation of CL data files
- Post processing CL data files to create G-code
- Cutter compensation adjustments
- Create manufacturing process drawings
