TME 210 - CNC Operation and Manual Programming
This course provides an introduction to the operation and manual programming of Computerized Numerically Controlled (CNC) machine tools including fundamental concepts, terminology and applications. The capabilities, advantages and disadvantages of numerically controlled equipment will be covered. Mathematical applications for definition of location, set-up, positioning and movement within specific coordinate systems will be presented. Various aspects of manual programming (G and M codes) and computerized conversational graphics modeling will be included. Criteria and practices basic to effective preventative maintenance, accident prevention practices and procedures, process planning, tooling, machine set-up and operation (dry-run, first and production runs) will be addressed also.
Upon successful completion of this course, students should be able to:
- Develop an appreciation for the aspects of Numerical Control (NC) and for production enhancement capabilities of Computerized Numerically Controlled (CNC) machine tools.
- Via manual methods, interpret and convert basic part drawings to procedural manufacturing process/operation, tooling and job plans for a CNC mill or a CNC lathe.
- Apply principles of mathematics, engineering piece-part print interpretation and geometric analysis techniques to describe a manufactured part’s datum points and planes, surfaces and feature locations in terms of two dimensional, interpolated machine axes and tooling positions.
- Utilize the concepts and techniques of manual programming to prepare and proof a written manuscript for the production of a manufactured part on a CNC mill and a CNC lathe.
- Demonstrate the ability to use concepts, techniques, hardware, software menus and computer system practices associated with a Computer Aided Machining/Distributed Numerical Control (DNC) system to write, save, retrieve and transfer CNC machine tool programs.
- Conduct CNC mill and lathe set-up, dry run, first run, inspection and adjustment techniques, and production run procedures and practices.
Prerequisite: Machining Technology (TME 111) or documented and demonstrable proficiency and competency developed from appropriate work/life experiences. (Contact program coordinator.)
