CNC Router Mastercam Programming consists of the following modules:

CNC Router Level I - This module covers 2 ½ axis toolpaths for milling such as: Contour, Pocket, Drill and Point. Parameters relevant to these topics are covered in detail, as are C-hooks, tool and material libraries, toolpath verification utilities and editors.

CNC Router Level II - Students use Mastercam to program advanced three-dimensional models using Multi-surf and Flow-line programming techniques.  

PREREQUISITE SKILLS AND KNOWLEDGE:  
MCH 282  

The student will be able to understand the operational basics of Mastercam required to design parts, assign toolpaths to specific part features, and communicate the CNC program to a CNC machine tool.  

This course is based on performance outcomes. The following performance outcomes are based upon established industry standards. The student will demonstrate knowledge and understanding of the following:

• Fundamental concepts and techniques associated with Mastercam CAD/CAM software.
• Fundamental machining operations performed on CNC Routers.
• Graphics environment of Mastercam Computer Assisted Machining Software.
• Mastercam process and modeling for Computer Assisted Machining for CNC Routers.
• Techniques of 2-D geometry construction using Mastercam computer assisted machining software.
• Concepts and techniques of modifying existing geometry using Mastercam
• Mastercam computer assisted machining software material and tool library files.
• Tool path generation using existing geometry utilizing Mastercam.
• Concepts of generating tool paths using the combined (existing geometry) and direct (new geometry) methods utilizing Mastercam.
• Concepts of tool path editing using Mastercam.
• Concepts and techniques associated with process and tool path planning using.
• Customization of the code generator through modification of the machine and template files using Mastercam.
• Concepts and techniques associated with constructing 3-D Wireframe models using Mastercam
• Concepts and techniques associated with toolpath generation of 3-D meshes (surfaces) using Mastercam.
• Concepts and techniques associated with the construction of derived and composite meshes (surfaces) using Mastercam.
• Concepts and techniques associated with 3-D toolpath planning using Mastercam.
• Concepts and techniques associated with 4th and 5th axis programming using Mastercam.
• Concepts and techniques associated with code file translation for successful CAD/CAM integration using Mastercam.

MCH 283 – CNC Router Mastercam Programming will be presented by means of audio-visual presentations, demonstrations, lab experiences, and research activities. The course activities and design emphasize the development of skills and knowledge outcomes prescribed by established industry standards. The identified outcomes will be achieved by means of individual and team activities.

POLICY - Student performance measurements are based on established industry standards. The various areas of study during the course will be evaluated by a variety of activities. Typical of those activities are the following;

1. READING ASSIGNMENTS - Information sheets, textbooks, journal articles and the learning resource center are potential sources of information that the student will reference as directed in the modules identified in the introduction. 

2. PRACTICE - Completion of tasks and projects identified in the reading assignments, information sheets, journal articles and textbooks. Students are required to complete practice activities with 100% competency.

3. SELF-ASSESSMENT - Checking and evaluating the students understanding and knowledge gained through the reading assignments and practices typically done through a practice evaluation.

4. LAB ACTIVITIES - Participation in structured laboratory exercises with the emphasis on developing skills or increasing expertise in the areas of study identified in the module packets.

5. FINAL ASSESSMENT - An assessment in the form of a written exam and/or practical application that addresses the subject areas identified in the module packets. Students are required to complete final assessment activities with 85% competency.
