MACH 241 CNC Machining I: CAD/CAM Geometry and Toolpaths6 credits
Students will learn to create geometry and toolpaths utilizing CAD/CAM software. They will utilize the Computer Aided Design (CAD) part of the software to develop geometry for manufacturing, such as wireframe and solid models. Students will utilize the Computer Aided Manufacturing (CAM) part of the software to create 2.5D toolpaths used in CNC machining to produce the geometry and models developed in CAD.
Prerequisites: MACH 143 , MACH 145 , MACH 162 , AND MACH 175
Corequisites: MACH 196
Course Outcomes
Upon successful completion of this course students will be able to:
- Utilize the CAD/CAM’s built in Help/Contents capability
- Create, modify, and manage basic 2D wireframe and 3D solid model geometry
- Create, modify, and manage Work Coordinates (WCS)
- Utilize different Construction Planes and Graphics Views
- Select the machine type and define the material type, material size, and various tool settings
- Organize multiple machining operations and their various toolpaths
- Create basic 2.5D toolpath while selecting the correct cutting tool and holder
- Determine tool cutter compensation and calculate the cutter speeds and feeds
- Verify 2.5D toolpath while checking for errors and crashes
- Generate the CNC code and Setup Information for manufacturing
- Create a program that includes the operations of: Slotting, Pocketing, Facing, Spotting, Chamfering, Drilling, Reaming, and Tapping
- Pass the CNC Machining test
