Chabot College Fall 2010 Course Outline for Machine Tool Technology 63B ADVANCED INDIVIDUAL PROJECTS

Catalog Description:

63B – Advanced Individual Projects 2 units (May be repeated 3 times)

Continuation of Machine Tool Technology 63A. Selected projects to provide certain specialized skills required for job updating, job advancement, or skill specialization. Strongly recommended: Machine Tool Technology 60A. 6 hours laboratory. [Typical contact hours: 105]

Prerequisite Skills:

Expected Outcome for Students:

Upon completion of the course, the student should be able to:

1. properly use precision measuring tools, such as the vernier caliper and height gauge, dial test indicator, and various types of micrometers; 2. set up and perform basic drill press, bandsaw, lathe, and vertical milling operations; 3. set up and do basic surface and cylindrical and grinding operations; 4. make precision layouts on the surface plate using precision layout tools; 5. apply basic mathematical formulae for calculating correct speeds, feeds, and values required for precision part layout; 6. inspect fabricated parts on a coordinate measuring machine; 7. write a “first article” inspection report for each assigned project.

Course Content:

This is a laboratory course only. Students are assigned selected projects to provide certain specialized skills they may require for job retraining, job advancement, or skill specialization.

1. Techniques: a. Set up lathe threading & cutting tools b. Clamp parts safely and securely in place for machining c. Set proper RPM’s and machine feedrates d. Edge finding and indicating vices, stock and partially machined parts e. Create part sketches from engineering drawings f. Proper tool usage and selection g. Proper cutting parameters and settings for milling machine tools h. Proper mounting and clamping of tools and parts i. Verification of size and Part Geometry with hand measuring tools j. Documentation techniques for part production k. Use of the single point flycutter for facing in the Milling Machine l. Identify and measure cutters, tools, video measuring tool, strap clamps and clamping techniques 2. Safety a. Safe operation of the machines and tools in the lab b. Safe workplace habits and procedures c. Safety test and safety evaluations Chabot College Course Outline for Machine Tool Technology 63B, Page 2 Fall 2010

Methods of Presentation:

1. Laboratory Manipulative skills instruction with informal student questions encouraged 2. Mockup and example presentations, safety movies, 3. Hands-on Demonstrations 4. 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 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?

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
