Dimensional Metrology Measurement and inspection of machining parts in accordance with current ANSI Y14.5m geometric dimensioning and tolerancing standard. Includes use of comparators, coordinate measuring machine, surface plates, hardness testing and quality control techniques. Precision Machining I and II Use of hand tools to produce layouts and objects. Theory and practice of grinding tool bits, turning, facing, taper turning, boring and threadcutting on lathe, drill sharpening, drill jigs. Operation and setup of lathes, grinders, mills, drill presses.
Second semester focuses on more advanced theory and projects.
Displacement, velocity and acceleration are calculated for various linkages. Cams, gears, and gear trains are analyzed. Manual and CAD techniques used. The design, selection, and practical application of machine elements such as fasteners, power screws, keys, couplings, springs, chain and belt drives, and bearings. Practical design problems with the aid of CAD, industrial catalogs and recent technological developments considered.
