Study Guide

Objective

Students will learn the functions of numerically controlled (NC) machines in today's field of engineering. They will understand NC programming and the manufacturing of products with an NC machine.

Content

- Types of NC machines and their functions
- Computerized production environment
- Using an NC machine and safety
- Attachment systems
- Tool systems
-Machining parametres
- G and M codes
- Machining co-ordinates
- CAM software and NC programming with a 3D model of a product

Students will do assignments using the CAM software.
