What is the function of the side angles of the lathe? How to choose
Deputy Angle mainly is to reduce the effect of friction between tool and machined surface, cylindrical cutting conditions, reduce pair of Angle, can significantly reduce the residual area after turning, improve workpiece surface finish.
The surface roughness is affected by the Angle between the subcutting plane and the assumed direction of the motion. According to the roughness requirement and tool strength of the machined surface. Reducing the subangle can improve the strength of the tool and improve the cooling condition, but may increase the friction and cause the vibration.
But the sub-deflection is too small to cause the vibration, and only when the rigidity of the tool tool of the machine tool is sufficient to take the smaller subangle. Generally use 3 ~ 10. When cutting in the middle, the Angle of the auxiliary Angle is 60, and the side Angle of cutting off the knife is 1 ~ 2.
