Students demonstrate the ability to follow safety procedures, read simple shop drawings, use bench tools, layout tools, power saws, and taps, grind a general purpose lathe bit, sharpen a general purpose drill, and identify the major parts of the engine lathe. Students single point external and internal unified screw threads to a Class 3 fit, generate angles with the compound rest within one degree, ream holes concentric within .001 inches, determine cutting speeds, and perform facing and turning operations. Students learn to hold .0005 inch tolerance internally, use an arbor and a sine bar, and taper within one minute angular tolerance.
Students read blueprints and interpret symbols, notes, dimensions, and tolerances.
Students determine hole locations by coordinates and degrees, use a rotary table, use a jig bore to drill holes by the coordinate method, and work within plus or minus .001 inch tolerance. Students identify the major parts and accessories for the horizontal mill, select cutters, mill slots, slab mill, and square a workpiece, and work within a tolerance of plus or minus .002 inches. Students indicate the head of a vertical mill, bore holes, drill holes at an angle, and work with tolerances of .0008 inches location and diameter. Students learn how to identify major parts and accessories of the surface grinder and grind flat, vertical, and angular surfaces to a tolerance of .0002 position and size. 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.
