5 Total Credits
Introduction to Computer Numerical Control (CNC) focuses on, reading basic G&M code, XYZ coordinates, establishing tool length offsets (TLO) using manual entry methods and automatic machine functions, and cutter radius compensation (CRC). Concentration on the role of rapid and feed override, distance to go, single block, dry run, and reading the program for successful crash avoidance. Special emphasis is on CNC equipment theory, functions and processes, maintenance of the machines, and machine setup. Students will learn maintenance of spindles, taper, fluid, coolant system and tool changer. Machine setup concentrates on tramming surfaces, establishing squareness to spindle, dialing in holes and bosses, setting TLOs, establishing coordinates, problem solving 3- axis setups, all while monitoring and troubleshooting machine noises and behavior.
