MET127 - Manufacturing Processes

Course Description

The main purpose of this course is to familiarize the mechanical / manufacturing engineering technology student with the principles and operation of manual and numerically controlled milling machines. Additional topics covered are the gear shaper, indexing head, and grinding machines. Measuring instruments, as well as additional manufacturing processes are also covered. Laboratory projects will be assigned to reinforce the topics covered in the theory. Prerequisite: MET 117 (1,3) 2 credits



To give students hands-on experience in the use of milling machines, NC programming, etc
