Catalog Description
Hours: 81 (27 lecture, 54 laboratory)
Description: Introduction to CAD/CAM using Fusion 360. Covers practical on-the-job skills needed for precision machining. Students will learn skills needed to read and understand detailed drawings, create a process plan for machining parts, create 3D CAD files from 2D drawings, create 2D drawings from 3D models, plan and create CNC toolpaths and export G-code for manufacturing. (not transferable)
Course Student Learning Outcomes

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.
