OPERATIONS PERFORMED ON MILLING MACHINE

- Jul 04, 2018 -

Face milling: •Machining is done by the teeth on the flat surface of the cutter, Finished surface is perpendicular to the axis of the cutter. Side and face milling: •Machining is done by the teeth on the flat as well as cylindrical surface of the cutter, finished surfaces are perpendicular as well as parallel to the axis of the cutter. Side milling: •Machining is done by the teeth on the cylindrical surface the cutter, Finished surface is parallel to the axis of the cutter.

OPERATIONS PERFORMED ON MILLING MACHINE : Profile milling: •The cutter has outline same as that of the shape of the profile. It is used for gear teeth manufacturing. End milling: •The machining is done by the cutter teeth on the end as well as periphery of the cutter. It is used for machining of complicated profiles. Gang milling: •Two or more milling cutters are mounted on the arbor. Horizontal and vertical surfaces are machined simultaneously.

OPERATIONS PERFORMED ON MILLING MACHINE : Saw milling( Slitting): •The thickness of cutter is small.(0.75 to 5 mm) It is used for cutting deep slots or for cutting off operations. Keyway milling: •Keyways can be prepared by using side and face milling cutter on horizontal milling machine or end milling cutter on vertical milling machine.

TURNING OPERATIONS INTRODUCTION : •This operation is one of the most basic machining processes. That is, the part is rotated while a single point cutting tool is moved parallel to the axis of rotation. •Turning can be done on the external surface of the part as well as internally (boring). •The tool's axes of movement may be literally a straight line, or they may be along some set of curves or angles, but they are essentially linear. •Performed on a machine tool called a lathe.

PRINCIPLE OF TURNING MACHINE: •Turning is a form of machining, a material removal process, which is used to create rotational parts by cutting away unwanted material. •The turning process requires a turning machine or lathe, work piece, fixture, and cutting tool. •Here the cutting tool remains constant and the work piece is in rotating motion.
