Machine Safety Precautions.
Milling Machines Use milling machines for shaping or dressing, cutting gear teeth, keyway slotting, splining, and similar work. These machines may be used for general purposes as well as special cutting operations. The following safety precautions shall be followed when using milling machines: Ensure that bed and work are clean prior to securing work to bed. Secure work to prevent movement during all phases of milling. Before setting up job, ensure that table, bore in spindle, arbor or cutter shank, and work is clean and free of chips, nicks, and burrs. Select a cutter of proper diameter. Do not change feed or speed while work is being cut. Lower table or raise spindle prior to moving or feeding work under a revolving cutter. Ensure that all clamps and bolts are low enough to pass under arbor and cutter. e. Shapers and Planers. Shapers and planers have a reciprocating, single-edge cutting tool, and are used for straight-line machining, surfacing, and similar work. The following safety precautions shall be followed when using shapers and planers: Be sure that work is tightly bolted to table or firmly held in vise and cutter raised above work before starting machine. Be sure that ram has adequate clearance before starting machine. Personnel operating shaper shall wear goggles. Stop machine completely when changing tools. f. Miscellaneous Machine Tools. Refer to the applicable machine maintenance manual for specific safety precautions. 2-3
