MILLING OPERATIONS TYPES OF MILLING MACHINES

Plain milling cutters that are more than 3/4 inch in width are usually made with spiral or helical teeth. A plain spiral-tooth milling cutter produces a better and smoother finish and requires less power to operate. A plain helical-tooth milling cutter is especially desirable when milling an uneven surface or one with holes in it. Types of Teeth

Sheet Metal Cutting - Manufacturing Process

Clearance is an important factor in the design of a sheet metal cutting process. As discussed earlier, cutting clearance is the straight line, lateral distance between the edge of the punch and the edge of the die hole. The way the metal separates, hence the cut, will be largely determined by the clearance.

Metal Cutting: Meaning, History and Principles | Metallurgy

Basically, the milling process is used to produce a plane or straight surface. The cutting tool used has multiple cutting edges. The speed motion is provided by the rotating milling cutter. The direction of the feed motion is perpendicular to the tool's axis of rotation. (v) Cutting-Off: Cutting-off is used to cut the metal into two parts.
