Course Learning Outcomes:

Students will demonstrate an advanced understanding of the personal and equipment safety considerations that are necessary for complex CNC machine tool programming and operation.
Given a CNC Mill, students will demonstrate an ability to write, simulate, and debug a part program utilizing advanced programming techniques such as cutter compensation, sub-programs, and canned cycles.
Given a CNC Lathe, students will demonstrate an ability to write, simulate, and debug a part program utilizing advanced programming techniques such as cutter compensation, sub-programs, and canned cycles.
Given a CNC Mill, students will prepare the machine to execute a program by applying advanced fixturing, tooling, and work-offsets techniques.
Given a CNC Lathe, students will prepare the machine to execute a program by applying advanced fixturing, tooling, and work-offsets techniques.
Given a part assembly, students will demonstrate an ability to write the required programs, manufacture and/or procure required fixturing, organize and assemble required tooling, and manufacture separate details to complete the assembly.
When communicating, use language that is appropriate to the audience.
Identify the best solution to a problem or issue.
