vise jaw within .001 of an inch and preset all the
tooling. Tools will then be loaded into the appropriate
holders and the preset values will be recorded
in the height offsets. The program reference
zero will be picked up and recorded in the
work offset. The program will then be loaded to
the Fanuc control and the setup will begin. Each
tool will be cycled through and offset adjustments
will be made. Once the part is finished a
fi rst piece inspection will be completed to make
sure the part is to print specifi cations. A short
production run will occur after the first piece inspection.
Numerical control machine orientation
and safe work practices will be covered. Each
student will setup and operate two CNC lathes
and two CNC machining centers.
PMT 121 Introduction to Threading
Processes
2 Credits (.5 Lecture 1 Lab .5 Shop)
4 Hrs/Wk (.5 Hr. Lecture 2 Hrs. Lab 1.5 Hrs.
Shop) *15 wks
This course covers the principles of single point
threading on the lathe. Methods of producing
both external and internal sixty degree screw
thread forms will be demon strated. Methods
of measuring screw threads utilizing the 3 wire
method and thread gages will be taught. Prerequisite:
PMT 111 or instructor permission.
PMT 122 Work Holding Methods for Milling
2 Credits (.5 Lecture 1 Lab .5 Shop)
4 Hrs/Wk (.5 Hr. Lecture 2 Hrs. Lab 1.5 Hrs.
Shop) *15 wks
Students will use different types of work holding
devices including vises, vee blocks, angle plates
and table setups. Machine maintenance schedules
are explored and practiced. The students
will use a variety of carbide and high speed
tooling to make parts that will be assembled as
a complete component. Students will be using
quality control techniques to check squareness,
parallelism, and hole to hole locations of their
manufactured parts. Prerequisite: PMT 116 or
instructor permission.
PMT 123 Intermediate Grinding
2 Credits (.5 Lecture 1 Lab .5 Shop)
4 Hrs/Wk (.5 Hr. Lecture 2 Hrs. Lab 1.5 Hrs.
Shop) *15 wks
This course is designed to expand upon the
grinding skills and technical knowledge acquired
in Grinding I. Students will learn to grind parallel,
square and to specifi c dimensions with +/- .001
tolerance. Stu dents will make projects from tool
steel that will be hardened and precision ground
to a fine finish. This course will include the introduction
of the Blanchard grinder and its use.
Instruction on radial Drill will be given along with
instruction on precision gage blocks and reaming
and tapping of holes. Prerequisite: PMT 113
or instructor permission.
PMT 124 Applied Computer Numerical
Control
2 Credits (.5 Lecture 1 Lab .5 Shop)
4 Hrs/Wk (.5 Hr. Lecture 2 Hrs. Lab 1.5 Hrs.
Shop) *15 wks
Students will build upon the PMT 115 and 117
courses taken in the fall. Programs written by
the students in the 115 class will be set-up,
proved out, and run in PMT 124. Students will
be introduced to more programming techniques
which will give them the skills to try the NIMS
level 1 CNC Milling and level 1 CNC Turning
parts. Students will also be introduced to editing
programs for errors, daily up keep of machines,
along with other basic shop activities that happen
during a normal shop day. Prerequisite:
PMT 115 and 117 or instructor permission.
PMT 204 Geometric Dimensioning and
Tolerancing
1 Credit (1 Lecture 0 Lab 0 Shop)
1 Hr/Wk (1 Hr. Lecture) *15 wks
This course is designed to introduce the students
to the basic principles of geometry dimensioning
& tolerancing related to the machine tool
industry. The content of this course is based on
the current standards set by the American National
Standards Institute (ANSI) 14.5 M-1994.
Prerequisite: PMT 103.
PMT 205 Intro to Master Cam
3 Credits (3 Lecture 0 Lab 0 Shop)
3 Hrs/Wk (3 Hrs. Lecture) *15 wks
This course is designed to introduce the basic
aspects of CNC milling and lathe programming
using Master Cam. Students will start by drawing
2-D models from a print and applying tool
paths to the model. Students will then move into
3-D modeling within Master Cam. Students will
then use the 3-D models they created to apply
advanced tool paths to. These advanced 3-D
tool paths will be applied to 3 and 4 axis CNC
milling centers. Students will also choose an
area of interest in machine programming to use
as an in-depth final project to share with the
class. Prerequisites: MTT 115, MTT 117, and
MTT 124 or instructor permission.
PMT 211 Advanced Threading Processes
2 Credits (.5 Lecture 1 Lab .5 Shop) 4 Hrs/Wk
(.5 Hr. Lecture 2 Hrs. Lab 1.5 Hrs. Shop) *15 wks
This course covers methods of machining 29
degree Acme single and multiple start screw
threads, methods of machining and measuring
tapers, and the use of the steady rest will be
demonstrated. The use of soft jaws will be emphasized
during this course. Prerequisite: PMT
121 or instructor permission.
PMT 212 Circular Milling Processes
2 Credits (.5 Lecture 1 Lab .5 Shop)
4 Hrs/Wk (.5 Hr. Lecture 2 Hrs. Lab 1.5 Hrs.
Shop) *15 wks
This course introduces the student to machine
maintenance and care. The student will be responsible
for machine maintenance and care.
The student will perform more complex milling
setups including dividing head and rotary table
work. The students will face mill parts using carbide
shell mills. The setup and broaching of a
keyway to print specifications will be covered.
An introduction to Lean Manufacturing will be
applied. Prerequisite: PMT 122 or instructor permission.
PMT 214 Advanced Computer Numerical
Control
2 Credits (.5 Lecture 1 Lab .5 Shop)
4 Hrs/Wk (.5 Hr. Lecture 2 Hrs. Lab 1.5 Hrs.
Shop) *15 wks
This course covers computer numerical control
programming with the aid of a computer using
Mastercam software. The student will input information
into the computer that will generate code
for the computer numerical control machines.
Circular interpolation, canned cycles, thread
codes and tool library data will be introduced to
the student. When the students complete their
program, they will manufacture complex parts
on the computer numerical control machining
centers and lathes. Prerequisite: PMT 115, 117
and 124 or instructor permission.
PMT 217 Introduction to Toolmaking
2 Credits (.5 Lecture 1 Lab .5 Shop)
4 Hrs/Wk (.5 Hr. Lecture 2 Hrs. Lab 1.5 Hrs.
Shop) *15 wks
This course will introduce the student to the
