Field trips
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 lab
manual Example: Sketch the proper tool position on a lathe turn and facing operation.
Show the orientation of the tool to the workpiece. Write down the tool speed (RPM)
settings and diameters which the speed would need resetting for the “step Turn Project”.
b. Laboratory assignment: Using a Milling Machine center drill and drill the holes for the
1.5” 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?
2. Methods of Evaluating Student Progress
a. Homework
b. Manipulative quizzes
c. Written laboratory inspection report on each part project
d. Fabricated parts checked to be accurate size and shape
e. Midterm manipulative examinations
f. Final identification and manipulative examination
Textbook(s) (Typical):
Operations Manual for Machine Tool Technology, Oliver, Chabot College Bookstore
This book was written by a former Chabot College Machine Tool instructor and is an exact
match for the projects, equipment, and operations that are taught in Chabot’s Machine Tool
Program.
