Measurable Student Learning Outcomes
1. (Comprehension Level) Describe the history, objectives and function of CNC controlled machines, and explain the advantages of CNC (I)
2. (Knowledge Level) Define the Cartesian Coordinate System, X, Y, Z axis nomenclature, incremental and absolute programming, including the ASCII (American Standard Code for Information Interchange) programming format for Word Address Language. (II)
3. (Synthesis Level) Write a CNC program to control CNC machine functions, multi-axis coordinate path and miscellaneous CNC machine functions. (III)
4. (Synthesis Level) Write, edit, save and retrieve a CNC program with an ASCII text editor. (IV)
5. (Application Level) Employ tool path verification with back plot software and CNC machine control verify mode. (IV)
6. (Synthesis Level) Use the multi-axis CNC machine to verify the CNC program. (V)
7. (Application Level) Prepare sequence of operation, determine necessary tooling, set tool length offset, and diameter offset variables to produce a CNC machined part from a dimensional annotated document. (VI)
8. (Application Level) Use linear and/or circular interpolation, apply a coordinate system, canned cycles, and miscellaneous functions, and all control variables to produce a CNC machined part from a dimensional annotated document. (VI)
