point of operation safeguarding of milling machines to the employer/user. Therefore, to prevent seri-ous injury resulting from the rotating cutter, flying chips, or splashing coolant, point of operation safe-guarding should be used on milling machines to the greatest extent practicable.
Milling Machines are used for machining solid materials, including metal, plastic and wood, and commonly used to machine irregular and flat surfaces. The cutter is designed to rotate during the operation as opposed to a lathe, where the part itself rotates during the cutting operation.
SAFEGUARDING: When safeguarding the point of operation on a cutting or turning machine, shields (barriers) can be installed between the hazard and the operator. These shields can also deflect chips, sparks, and coolant that are generated at the point of operation.
