Kneel for the difference between the blade and the edge of the blade.
It is. Damping along the cutting edge is in the knife surface grinding width is small, the Angle ? o1 < 0 ? chamfer surface, enhances the tool squeeze damping effect, help to eliminate the low frequency vibration in the process of cutting. Negative chamfer width ? 1 b is associated with cutting thickness ? c, b ? usually 1 = f (0.3 ~ 0.8), take larger value when rough machining, finish machining of small value. The carbide cutting tools, take ? ? ~ o = - 5-10 ?. Vibration free edge width b ? 1 = 0.1 ~ 0.3 mm, ? o1 ? ~ = - 5-10 ?.
Negative chamfer is in front of the positive rake Angle along the cutting knife surface grinding width is small, anterior horn ? o1 to 0 or less ? chamfer surface, its role is to enhance a cutting edge, especially to the poor impact toughness of the cutting tool material, can reduce the tool breakage.
Negative chamfer is in front of the positive rake Angle along the cutting knife surface grinding width is small, the forefoot gamma 08 or less chamfer surface, its role is to enhance a cutting edge, especially to the poor impact toughness of props material, reduces the props along the cutting vibration free edges is broken in the blade surface grinding width is small, the Angle of alpha < 08 chamfer surface, enhances the tool squeeze damping effect, help to eliminate the low frequency vibration in the process of cutting.
