Course DescriptionsMACH220 CNC Milling Operations Level 1Credits: 3Co-requisites: MACH205Prerequisites: Completion of 1st SemesterThis course is an introduction to CNC Milling Centers. Thecommon operating procedures, set-up, and maintenanceof the machine and control panel will be discussed andimplemented. The student will become aquainted with theways in which various companies utilize CNC machine toolsand personnel while learning methods for the installation oftools, establishing machine, fixture, and part zero referenceoffsets. The students will also be introduced to the methodsand reasons behind the modification of these reference offsetsand other geometry offsets used to machine parts to demandinggeometric tolerances.MACH222 CNC Milling Programming and Operations Level 2Credits: 3Prerequisites: MACH220This class introduces students to word address programming(G and M code) for CNC Machining Centers. The student willwrite formatted programs, set up, and run their programson the CNC Machining Center. Students will use basic andintermediate “G” codes with coordinates to create commonpart features such as contours, slots, bores, holes and pockets.The goal will be to prepare, plan, then write safe, effective, andefficient CNC programs. Students will then use key concepts forpart set-up, program verification, editing, and documentation.MACH224 CNC Milling Programming and Operations Level 3Credits: 3Prerequisites: Completion of 1st YearCommon uses of the CNC Machining Center are discussed andimplemented. Canned cycles for pocketing, hole manufacturing,threading, cutter compensation, and other standard controllerfeatures will be utilized. Students will learn to use loops,multiple work offset programming techniques, subroutines,and subprograms to shorten and simplify programs. All theseprogramming approaches will be performed on 3 axis and 4 axismachining centers. Students will also learn advanced techniquesfor making programs run more efficiently.MACH241 CAD/CAM for the CNC Turning CenterCredits: 5Co-requisites: MACH218Prerequisites: Completion of 1st YearThis class introduces students to Mastercam X for Lathe / Turningapplication. Students will learn to navigate the program’s GUIinterface for the purpose of 1) creating part geometry as CADentities; 2) defining cutting tools and machining operations; 3)generating CAM type tool paths; 4) graphically render theirmachining operations for verification purposes; and 5) postprocess their work. Students will then have the opportunity toload their programs into a CNC Turning Center and performall necessary tasks to complete the manufacturing process fortheir piece part. This class will walk a student through theentire creative process of part design, manufacturing processdevelopment, and machining a finished product.MACH242 CAD/CAM for the CNC Machining CenterCredits: 5Co-requisites: MACH224Prerequisites: Completion of 1st YearThis class introduces students to Mastercam X for CNC Millingapplication. Students will learn to navigate the program’s GUIinterface for the purpose of 1) creating part geometry as CADentities; 2) defining cutting tools and machining operations; 3)Generating CAM type tool paths; 4) graphically rendering theirmachining operations for verification purposes; and 5) postprocessing their work. Students will then have the opportunityto load their programs into a CNC Milling Center and performall necessary tasks to complete the manufacturing process fortheir piece part. This class will walk a student through theentire creative process of part design, manufacturing processdevelopment, and machining a finished product.MACH245 MetallurgyCredits: 1Prerequisites: MACH110The student will learn about types of ferrous and nonferrousmetals and their applications. Metal numbering systems andthe types of heat-treating will also be covered.MACH250 Shop PracticesCredits: 2Prerequisites: MACH110, MACH115, MACH120 andMACH125This is an on going semester course during normally scheduledshop hours. It is intended to match spring semester studentswith live, practical shop experiences involving subject matterpreviously covered in other courses. Emphasis will be onproductivity.MACH260 Project ManagementCredits: 2Prerequisites: MACH140 and MACH245During the final semester of course work, the student will workwith an assigned advisor from the machine shop. This twocreditcourse will be the capstone project and will demonstratea comprehensive knowledge of topics and concepts covered inthe Metals Technology program.MECH205 Small EnginesCredits: 2Prerequisites: noneThis course concentrates on small gasoline engines as used inthe Outdoor Power Equipment industry (less than 20 horsepower). Emphasis will be on the four major theories of smallengines-compression, ignition, carburetion, and governing.Students will disassemble, familiarize, inspect, reassemble, andoperate a school-owned small engine.NASX105 Introduction to Native American StudiesCredits: 3 Offered Spring SemesterPrerequisites: noneStudy of cultural makeup of Native Americans in Montana andsubsequently in the United States. Education, historical, legal,and social aspects will be analyzed for their influence on themodern Indian culture.UM-Helena College of Technology 2011 - 2012 Academic Catalog 113
