These are the points of operation, power transmission apparatus, and operating controls: 1. Point of Operation - points where machine tasks are performed (e.g. shaping, boring, cutting) 2. Power Transmission Apparatus - All components that transmit energy (e.g. gears, cranks, flywheels, belts, pulleys, chains, cams, spindles, couplings, connecting rods) 3. Operating Controls - Other moving parts like transverse, reciprocating, and rotating parts including auxiliary and feed mechanisms
