MTT 230 - Electrical Discharge Machining

Institution:

Delaware County Community College

Subject:

Machine Tool Technology

Description:

This course is designed to provide the student with the information and basic skills required to program and operate both ram (sinker), and 4-axis wire (EDM) Electrical Discharge Machining/machines. Instruction will address the fundamental principles of the EDM process, terms, capabilities, and machine tool system components. Aspects of programming and machining methodology, to include; work holding, tooling, electrode selection and operational characteristics, process variables, set-up and operation of ram and wire machines will be addressed. Upon successful completion of this course, students should be able to: Cite in writing, the principles of operation for the EDM process; Identify the function and the components, and operational characteristics, as well as the operation parameters, of typical ram and wire EDM machine tools; Compare and contrast requirements for ram and wire EDM machine maintenance, set-up and operation; Summarize the various types of electrode materials and designs, as well as their application; Explain the design and operational characteristics a ram type electrode must exhibit in order to perform appropriately; Interpret work order requirements and set-up a typical ram, and a wire EDM machine tool for production; Set-up and operate a ram and a wire EDM machine tool in order to achieve desired inspection/quality characteristics on a finished part; Analyze part geometry requirements and create Computer Numerically Controlled (CNC) piece-part programs, incorporating control of various processes and machining parameters for machining on a ram; and, a 4-axis wire EDM machine; Utilize CAM software programming options to modify cutting parameters and settings, part geometry at various points on a contour; Conduct service and maintenance functions typically assigned to an EDM machine tool operator.
