Students identify the major parts and accessories of the tool and cutter grinder, sharpen two flute end mills, four flute end mills, slab mills and form cutters, and work within a plus or minus .001 tolerance. Students use the control functions and the letter address system and the program format to set up and operate the machines. Students write process sheets, estimate machining time, perform final inspection on the finished parts, and use any machine in the shop to produce the part. Students use the principles of grinding wheel selection and do form, cutter surface, and cylindrical grinding within a tolerance of .0001. Students identify metallurgical terms and definitions and interpret data from handbooks on selection, heat treatments, machining, and welding of metals.
Students learn how to sketch, build, set, and operate a simple punch die.
Students identify different types of lubricants, oil machines, and disassemble, repair, and reassemble machine slides and gear boxes to manufacturer s specifications. All types of dimensioning, symbols, notes, and tolerances are interpreted. This course introduces the student to the concepts of numerical control. They write NC lathe programs which contain linear and circular interpolation, threading, drilling, turning, and boring. Students proof the programs, punch NC tapes, and run the programs on the NC Lathe.
