2011 - 2012 Student Calendar - Helena College of Technology

Course DescriptionsMACH125 Blueprint Reading for the MachinistCredits: 2Prerequisites: MACH110Blueprint reading covers orthographic projection, lineidentification, auxiliary and sectional views, dimensioning ofdrawings, common abbreviations, tolerancing, and sketchingtechniques.MACH132 Advanced LathesCredits: 5Prerequisites: noneThe Advanced Lathe course will use engine lathes to manufactureindustrial parts. The use of assorted cutting tools and supporttooling, such as form tools, carbide inserts, taper attachments,follower, and steady rests. Close tolerance machining required.Actual customer projects will be incorporated into the coursework. Safety concerns for both machines will be reviewed.MACH137 Advanced MillsCredits: 5Prerequisites: noneThe Advanced Mills course will utilize the horizontal andvertical mills in the lab. The use and care of rotary tables,indexing heads, end mills, slab mills, gear cutters, carbidecutters, criterion, and line boring will be covered. The variouswork holding methods, location methods, process planning andoperations will be discussed. Safety concerns for both machineswill be reviewed. Actual customer projects will be incorporatedinto the course work.MACH140 Grinding ApplicationsCredits: 2Prerequisites: noneThe course covers setup, use, and safety requirementsof grinding machines. Hands-on use of machines will beemphasized.MACH205 Tooling and Fixtures Used in CNCCredits: 2Prerequisites: noneTooling and fixtures used in CNC are discussed in a classroomenvironment. These topics, for both mill and lathe, will bediscussed in order to facilitate the students’ ability to selectproper work holding devices and cutting tools for various typesof machining operations that may be performed. Cutting toolinformation is one of the most multifaceted areas of study fordeveloping machinists and programmers. Both must be able todiscern proper set-ups based on part and tool geometry whileproviding proper speed and feed data. The use of formulas andreference materials will be studied as a necessary facet of themanufacturing process.MACH210 CNC Turning Operations Level 1Credits: 3Co-requistes: MACH205Prerequisites: Completion of 1st SemesterThis course is an introduction to CNC Turning Centers and thesafe operation of common operating procedeures, set-up andmaintenance of the machine and control panel, which will bediscussed and implemented. The student will become aquaintedwith the ways in which various companies utilize CNC machinetools and personnel while learning methods for the installationof tools, establishing machine, fixture and part zero referenceoffsets. The students will also be introduced to the methods andreasons behind the modification of these reference offsets andother geometry offsets used to machine parts to demandinggeometric tolerances.MACH212 CNC Turning Programming and Operations Level 2Credits: 3Prerequisites: MACH210This class introduces students to word address programming (Gand M code) for CNC Turning Centers. The student will writeformatted programs, set-up, and run their programs on the CNCTurning Center. Students will use basic and intermediate “G”codes with coordinates to create common part features such ascontours, shoulders, bores, grooves, and chamfers. Studentswill learn to apply geometry offsets for machining their partsto exacting geometric tolerances. The goal will be to prepare,plan, then write safe, effective, and efficient CNC programs.Students will then use key concepts for part set-up, programverification, editing, and documentation.MACH218 CNC Turning Programming and Operations Level 3Credits: 3Prerequisites: MACH210 and MACH212This class enhances a student’s ability to program, set up, verifyand operate CNC Turning Centers. The student will write wellformatted CNC programs, utilizing strategic programming andlogic techniques and CAD / CAM generated files, then set-upand run their programs on various CNC Turning Machines.Students will use “canned cycles” and intermediate level “Gand M” codes to create common part features such as contours,grooves, bores, holes and threads, with an emphasis placed onInternal Diameter (ID) operations. The goal will be to prepare,plan manufacturing process, then write safe, effective, andefficient CNC programs. Students will then use key concepts forpart set up, program verification, editing, and documentationof process.112 2011 - 2012 Academic Catalog UM-Helena College of Technology
