Project 2

Students are required to machine to specifications the attached part as noted. The project will require milling, drilling and reaming. A drawing, a piece of aluminum, and a Quality Assurance Traveler (QAT), will be provided for the completion of this project. The work piece will be machined to the specifications illustrated on the drawing. Each dimension listed on the QAT must be checked by the student and written on the QAT. Each student's work piece and QAT will be randomly checked by the instructor. If a dimension is "out of print", the student may elect to lose the points and continue to complete the project or, start over.

In addition, a CNC program should be written and attached to the completed part. The program should be written only for drilling the four holes indicated and will be graded on its format, completeness, correctness, quality and safety as discussed in class. You must show your own drawing or sketch, tool origination point, tool path, operation sequencing, and completed program. The program is worth 25 points and will be factored into your total score on the machining portion.
