MTT 210 - CNC Machine Tool Operations

Course Description

This course is designed to provide appropriately prepared conventional machine tool operators with an introduction to Computerized Numerical Control (CNC) machine tool set-up and operation. Theory will be practical in nature and relate directly to shop based applications. Lathe, and mill, operations will be stressed; however, the theory and concepts will be applicable to various CNC machine tools. Upon successful completion of this course, students should be able to: Conduct commonly assigned CNC machine tool operator cleanup and maintenance activities. Describe the various axes and coordinate systems associated with differing CNC machine tool types. Apply accident prevention practices and procedures while interacting with the Machine Control Unit (MCU), as well as during program proof-out; and, while performing maintenance. Discuss the types and principles of MCU offset registers, and their usage. Analyze rudimental program problems and perform basic editing operations to modify G-code programs via Manual Data Input (MDI) operations. Edit canned cycle functions utilizing calculations/data prepared by others to create simple G-code programs via conversational graphics as well as by typing on a personal computer. Demonstrate upload/downloading and other Distributed Networked Computer (DNC) functions on a shop floor computer network. Set-up, align, and zero-out workholding devices, tooling adapters, and toolholders. Perform dry/first/production runs and inspections, adjusting various register values to assure tool qualification, and part dimensionality. Communicate and apply piece-part set-up and inspection procedures commonly associated with, advanced Lathe and Milling Operations.
