Occupations | Sets up swiss-type automatic screw-machines to perform series of machining operations, such as boring, threading, and facing metal wire, rod, or bar stock to specifications, to produce small, accurately turned parts for clocks, watches, and other timing devices: Studies blueprint and layout sheet to determine machining to be done, dimensions of parts, and permissible tolerances, and plans sequence of operations. Visualizes movements of machine parts, workpieces, and tools in each operation in relation to others and decides on station and timing of each operation to assure efficient use of tools and time. Selects cutting speeds, feed rates, depth of cuts and cutting tools to be used on basis of experience and knowledge of metal properties and shop mathematics, or by referring to tables, charts, or instructions on layout sheet. Installs stock feed pushers, collets, and bushings, using wrenches. Inserts stock into stock feed mechanism and sets stock stop to control length of stock fed. Installs spindle speed and feed change gears to obtain required spindle speeds and tool feeds. Installs cams that control movement of stock and tools. Mounts cutting tools in toolholders and mounts them on machine, using wrenches, verifying their position with gauges and other measuring instruments. Cranks machine through cycle, stopping machine and adjusting tool positions and machine controls to allow for such factors as timing and clearance between moving parts. Starts machine, observes operation, and verifies conformance of first-run and sample workpieces to specifications, using such instruments as micrometers, calipers, limit gauges, and scales. Replaces worn tools. May operate $T3bench grinder$T1 or cutter-grinding machine to sharpen tools. May set up and operate machine to machine first-run workpiece only. May be required to have experience with particular product, or machine of particular size, type, or trade name. (references) |
