CNC07002 2015 Computer Aided Manufacture (CAM/CNC) 301
This module is designed to enhance a students skills in the area of Computer Aided Manufacture (CAM) and CNC machining. The aim of this module is to give the student the skills to manufacture precision components using CAD/CAM software and be able to setup and operate CNC machines. The main focus of this module is 2D programming on CNC mills and 2 axis programming on CNC lathes.
Learning Outcomes
On completion of this module the learner will/should be able to;
Interpret engineering drawings and select appropiate machinining processes.
