Lathe and Vertical Milling Machining II

Techniques and procedures taught in MACH 118 are enhanced
and reinforced. This course introduces students to more advanced
techniques and procedures used on the lathe and the vertical
milling machine.
Prerequisites: MACH 106 and MACH 118

MACH 161 (2 credits)
Metallurgy

Covering the basic principles of metallurgy, this course clarifies
many industrial processes. Students gain an understanding
of quenching, annealing, case hardening, tempering, and
crystallization.

MACH 168 (3 credits)
Machine Skills Lab

This is a lab intensive course which provides students with
extensive hands-on training. Assigned projects aid students
in gaining critical experience contributing to a well-rounded
machining education.
Prerequisites: MACH 112, MACH 118, MACH 123, and MACH
158

MACH 172 (3 credits)
Computer Numerical Control (CNC) I

Introducing students to basic CNC concepts, this course explains
and exercises Cartesian coordinates, codes, positioning systems,
tooling, and word address programming.
Prerequisite: MACH 118

MACH 222 (3 credits)
Computer-Aided Design
Machining (CAD/CAM) I

and

Computer-Aided

This course introduces the use of MasterCAM® as a tool for
defining part geometry and generating CNC machine code. Two
axis and three axis applications are demonstrated, along with the
use of the CAD/CAM applications. The AutoCAD® system is
introduced as a drafting system to be linked with MasterCAM®.

MACH 227 (3 credits)
Computer Numerical Control II

This course expands upon introductory concepts learned in CNC
I and provides for increased hands-on application of learned
material. Some advanced programming techniques include
circular interpolation, cutter, compensation, and subroutines.
Students learn how to inspect precision parts with the coordinate
measuring machine and are required to complete specific
laboratory work to gain confidence in working with the CNC
machines.
Prerequisite: MACH 172
