This document contains two units for an advanced course in computer numerical control (CNC) for computer-aided manufacturing. It is intended to familiarize students with the principles and techniques necessary to create proper CNC programs using computer software. Each unit consists of an introduction, instructional objectives, learning materials, learning activities, and assignments. The units cover the following topics: (1) EZ-MILL, a computer software program devoted to milling operations, that students use to describe a part and to use that description to write a CNC program; and (2) EZ-EDM, a software package designed to create parts programs for electrical discharge machining (EDM). Instructional materials are illustrated with line drawings. (KC)
