List any other operation in milling process. a) Peripheral milling Slab Milling-Cutter width extends beyond the work piece on both sides. Slot Milling-Cutter width is less than the work piece width, creating a slot. If the cutter is very thin, it can be used to cut a work part into two, called saw milling.
اقرأ أكثرGroove or slot milling is an operation in which side and face milling is often preferred to end milling. Slots or grooves can be short or long, closed or open, straight or non-straight, deep or shallow, wide or narrow. Tool selection is normally determined by the width and depth of the groove and, to some extent, length.
اقرأ أكثرMilling machines may be manually operated, mechanically automated, or digitally automated via computer numerical control. Milling machines can perform a vast number of operations, from simple (e.g; slot and keyway cutting, planning, drilling) to complex (e.g; contouring,diesinking).
