Course Outline for Machine Tool Technology 60A
Catalog Description:
60A – Machine Tool Technology I
(May be repeated 3 times)
4 units
Introduction to machine tool operations relating to precision measuring tools, layout methods, screw
threads, benchwork, drill presses, bandsaws, optical and manual inspection techniques, basic lathe
and vertical milling operations, and evaluation of manufacturing job opportunities. Emphasis on safe
and correct use of hand and machine tools. 2 hours lecture, 6 hours laboratory.
[Typical contact hours: lecture 35, laboratory 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, vernier height gauge, dial
test indicator, and various types of micrometers, also optical / video measuring machines;
2. perform common bench operations, such as filing, sawing, deburring and hand threading;
3. set up and perform basic drill press, bandsaw, lathe and vertical milling machine operations;
4. make precision layouts on the surface plate using precision layout tools, such as the vernier
height gauge, angle plates, parallels, and V-blocks;
5. apply basic mathematical formulas for calculating correct speeds, feeds, and data required
for precision part layout;
6. evaluate a blueprint to make a manufacturing plan to produce the desired machine part;
7. safely setup and operate a manual lathe to make a 60 Degree threaded shaft;
8. safely setup and operate a manual milling machine to make a prismatic part manufactured
within the part drawing tolerances and geometrically shaped part;
9. offhand grind a High Speed Steel Toolbit to a tolerance of +/- 1 degree for each of the tool’s
six major cutting or clearance angles as described in the Machine Tool Laboratory Manual;
10. measure the parts manufactured and evaluate whether the piece part is acceptable to the
print tolerance, geometries and published machining standards like ANSI Y14.5M.
Course Content (Lecture):
1. Precision measuring tools, standards, micrometers, calipers height gages, precision pins
2. Identity of benchworking tools such as the combination square set, trammel points, center /
prick punches, wrenches and hammers
3. Layout methods, blueprint interpretation and part layout techniques
4. Screw threads types, styles and dimension standards
5. Drill presses, includes chuck and tapered drills and speeds and power feeds
6. Explanation and examples of bandsaw operations, including safely setting speeds and
welding new blades
7. Basic lathe operations, including turning, facing, drilling, tool and machine setup & beginning
8. Basic vertical milling machine operations, speeds and feeds, identifying parts components
and accessories, setup clamping and indicating methods and techniques
9. Evaluate and inspect parts produced in class and prepare Laboratory Inspection Reports
10. Manufacturing / fabrication Job opportunities, specialties and trends

Course Content (Laboratory):
1. Typical Techniques
a. Set tool Height and angles
b. Set chuck parameters indicate to .001” TIR
c. Face Cut the parts to Blueprint specifications
d. Turn each of the steps of the “Step Turn Project” to +/- .001” per Blueprint
e. Cut the 45 Degree Chamfer X 1/16” by compound Rest Setup and Operations, Inspect to
published tolerances
f. Set Milling Machine to Proper cutting parameters
g. Cut the ID Slot ¼” X .020 Deep 1.00” Long
h. Edge finding and indicating part stock and vices
i. Create part plans from engineering drawings; have your instructor signoff
j. Inspect parts produced and write a Laboratory Report on machining successes and
failures analyzing why problems were encountered and what remedies where developed
and implemented for remediation of the scrap part
2. Safety
a. Safe operation of the Lathe / Milling Machines and Grinders, including all tools used to
cut form or inspect the project parts
b. Develop safe skills and habits while following posted machining procedures
Methods of Presentation:
1. Lecture, informal with student questions encouraged
2. PowerPoint presentations, videos, safety and application movies, and overhead
3. Hands-on Demonstrations and interactive participation while in lecture
4. Field Trips / on-site manufacturing visits
Assignments and Methods of Evaluating Student Progress:
1. Typical Assignments
a. Homework: 1-2 worksheets each week on the material covered in the texts and in lecture.
Example: Sketch the C-Clamp project, draw in the tool and cutting locations, and
calculate their X - Y coordinate positions.
b. Laboratory assignment: Manufacture a complete C-Clamp project and all 6 of the detail
parts of the C-Clamp Assembly to published blueprint standards and practices. Verify the
thread sizes to a class 3A published in the Machinery Handbook. Maximum Pitch
Diameter .3344” and Minimum .3311” Minimum. Inspect the other parts on the Video
measuring machine and recreate a “first article” inspection report. Did the part pass
inspection? Why?
2. Methods of Evaluating Student Progress
a. Homework
b. Quizzes
c. Written laboratory inspection report on each part project
d. Fabricated parts checked to be accurate size and shape
e. Midterm examinations
f. Final examination

Textbook(s) (Typical):
Machine and CNC Technology, Fitzpatrick, Career Education; 2004*
*Rationale: This book more completely covers the subject matter taught in Chabot's Machine Tool
Technology program than any other text book we have found. The new edition is due out in
the first quarter of 2010. We will adopt that edition if, after review, we feel it continues to
meet our needs.
Operations Manual for Machine Tool Technology, Clifford Oliver, Chabot Bookstore*
*Rationale: 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.
Machinist Ready Reference, Weingartner, Prakken Pubn; 2007
Special Student Materials:
Machine shop approved safety goggles
Sharp EL-531W scientific calculator
Plastic circle template, 6” rule, protractor, compass
USB drive – 1gb minimum
Combination or keyed padlock
Students are encouraged to purchase tools, a list given by the instructor, to use in class as a
start to entering the work world, but are not required to do so.
