CAD 235 - Introduction to Mastercam

Credits: 4
Focuses on rapid prototyping and basic toolpaths using Mastercam software. Includes creation and editing of 2-D geometry, 3-D wire-frame modeling, 3-D solid modeling, and 3-D surface modeling. Students use programming 3-D toolpaths from 3-D wire-frame models and 3-D derived and composite surface and solid models. Covers toolpath editing including project and trim functions, as well as production of prototype model using the milling machine. Discusses the verification and editing of toolpath programs using rendered backplots. Previously D T 237.

Enrollment Requirement: Instructor consent.

Course Outcomes:
Students who successfully complete this class will be able to:

Create and edit surface and solid models in Auto CAD and Mastercam.
Create compiled files for the 2 different CNC cutting machines.
Trouble shoot files within the software to verify compliance
Load and “Zero” out the machine in preparation for running the program
Use Matercam to create the cutting paths for described projects.

Program Outcomes

Apply computer and engineering office software for documentation, communication and approval within an engineering office environment.
Apply current ASME Y14.5, machining and AWS symbology for industry production and documentation.
Create accurate solid model computer files to output designs to 2-D documentation, 3-D printing, and CNC machines, using feature based solid modeling or Boolean based construction methods.

College-wide Outcomes

Critical Thinking -Critical thinking finds expression in all disciplines and everyday life. It is characterized by an ability to reflect upon thinking patterns, including the role of emotions on thoughts, and to rigorously assess the quality of thought through its work products. Critical thinkers routinely evaluate thinking processes and alter them, as necessary, to facilitate an improvement in their thinking and potentially foster certain dispositions or intellectual traits over time.
Responsibility - Responsibility encompasses those behaviors and dispositions necessary for students to be effective members of a community. This outcome is designed to help students recognize the value of a commitment to those responsibilities which will enable them to work successfully individually and with others.
Quantitative and Symbolic Reasoning - Quantitative Reasoning encompasses abilities necessary for a student to become literate in today’s technological world. Quantitative reasoning begins with basic skills and extends to problem solving.
