Assignments and Methods of Evaluating Student Progress:
1.
Typical Assignments
a.
Homework: 1-2 worksheets each week on the material covered in the laboratory and
laboratory manual. Example: Sketch the proper tool position on a mill for end milling and
facing operations. Show the orientation of the tool to the workpiece. Show whether the
operation is climb milling or conventional milling. Write down the tool speed (RPM)
settings and feedrates (IPM) at which the cut would need resetting for the “1.5” parallel
Project”.
b.
Laboratory assignment: Using a Milling Machine center drill, drill and ream the holes for
the 1.0” parallel Project, as shown in the Engineering drawing. Test run each tool
operation checking for accuracy and proper tool cutting direction. Center drill only the
first hole and measure the center drilled location per the print. Continue to machine the
balance of the holes to fabricate the part. Inspect the part with a dial caliper “in process”
and create a “first article” inspection report. Did the part pass inspection? If not, why?
