Metal hardware cutting tool materials and tools, knowledge structure

Cutting Angle

Although many types of cutting tools, but they are cutting part of structure elements and the geometrical angles have many common characters. As shown, all sorts of more complex tools, tools or gear its a knife, equivalent to a turning of the cutter.

Starting from the tool, below are analyzed and studied.

1 the cutting tool parts

Cutting tools is made up of three parts, namely, composed of knife knife, the former vice-president and cutters.

(1) the knife cutting tools before the surface flow. (2) after the blade with metal hardware tools on the surface of the cutting of the relative surface. After the knife knife before: the formation of the intersection of cutting edge cutters. After the knife: vice knife with former deputy cutting edge intersection formed after the blade. (3) the cutting edges

Before cutting edge cutting knife refers to the underlying surface with the blade, cutting the cutting edge cutting edge and vice.

Main cutting edge is cutting edge on the landform began to zero point, and at least a cutting edge in the workpiece to prove that the whole period of transition surface cutting edges. Cutting, the main cutting work by it to burden.

Vice is refers to a cutting edge cutting edge on the cutting edge of the outside, also begins the landform is zero point, but it to deviate from the direction of the cutting edge.

The cutting edges refers to the role in a particular moment, on the cutting edge in actual work, and in metal hardware cutting in transition surface and surface processing of blade already. For the difference in the Lord, respectively, before cutting edge dubbed "work" or "action" 2 words.

Tip: the main cutting edge and cutting edge is part of the joint point, as less.
