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

  • CSLO #1: Demonstrate safety standards for both a learning lab environment and worksite environment for metal working including cutting, machining, forming and assembly.
  • CSLO #2: Apply the terms used in this industry: chip hook, coolant, geometric control, burrs, height gage, indicators, toolpath and clearance.
  • CSLO #3: Operate various types of machines in performance of construction of assigned project(s).

            Methods of Instruction

            • Laboratory
            • Lecture/Discussion
            • Distance Learning

            Lab:

            1. The instructor will demonstrate how to align the vise to the X & Y axis of the milling machine, followed by the student demonstrating the process safely.

            Lecture:

            1. Instructor lecture on creation of CAD drawings followed by students outlining the steps to creating a CAD drawing.

            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.
