Precision Machining Technology Curriculum Guide and Course Descriptions

The Precision Machining Technology program is designed to give students the skills necessary to become gainfully employed in the manufacturing industry. Industry provides many jobs for machinists who operate machine tools that use different metals to form specific products through the use of drills, lathes, milling, grinding and Computerized Numeric Controls (CNC). Selecting the proper materials and tools, planning the project sequence according to the blueprints or written specifications, and forming the metal product while holding accuracies to within thousandths of an inch are skills obtained through the understanding of dimensions, units of measure and measuring instruments that are necessary for proficiency in machine technology.
