Catalog Description

Hours: 90 (36 lecture, 54 laboratory)
Description: Introduction to Computer Aided Design (CAD) parametric modeling and Computer Aided Manufacturing (CAM) using CAD/CAM software. Covers practical on-the-job parametric modeling skills needed for precision machining. Students will learn skills needed to read and understand detailed drawings, create 3D CAD model files, develop a process plan for machining parts, and create CNC tool paths for manufacturing processes. (not transferable)

            Methods of Instruction

            • Laboratory
            • Lecture/Discussion
            • Distance Learning

            Lab:

            1. The instructor will demonstrate how to align the coordinate system on a CAD model in the CAM software interface to the Work Coordinate System (WCS) of a milling machine work holding fixture, followed by the student practice.

            Lecture:

            1. The instructor will lecture on creating a fully defined CAD model from a technical drawing, followed by students outlining the steps to create a fully defined CAD model.

            Distance Learning

            1. Instructor provides how-to tutorial on creating a "lego block." Students are expected to follow steps to re-create the lego block using CAD software.

            Typical Out of Class Assignments

            Reading Assignments

            1. Read chapter from text on understanding chip development of central focus point called interference contact. (IX - rake, clearance, cutting angles). Be prepared to discuss in class. 2. Read chapter measurement and be able to identify three methods to measure the 1.75 inch diameter hole within 0.0005 tolerance. (XIII - Inspection methods).

            Writing, Problem Solving or Performance

            1. Experiment #1: Using modeling clay, try varying the rake angle comparing positive rake vs negative rake. (XI - define the shear line in a chip). 2. Machine center holding tooling, identify fixture and material holding.
