INDS 220 - Basic Machine Operation3 Credit: (1 lecture, 3 lab, 0 clinical) 4 Contact Hours: [(INDS 122 or Math Level 3 ) and TDSN 105 ]
This course focuses on the theory and practice in the basic operations of typical machine tools such as lathes, mills, drills, and grinders and the use of precision bench tools and layout equipment. The course provides the definition, history, operation, modern development and application of the various tool room machines, practical knowledge of machine processes, and basic machine shop skills. The machinist handbook will be reviewed and used as a reference throughout the course and can either be purchased or downloaded to a personal device.
