Abstract
PURPOSE: To reduce the roughness of the worked surface of a workpiece to the minimum degree be detecting the repulsive force in cutting which operates onto a tool and permitting the tool to be set automatically at the angle in which the cutting edge angle before operation is nearly zero, on the basis of the repulsive force in cutting.
CONSTITUTION: As the surface roughness IV becomes the minimum when the cutting edge angle before operation is nearly zero, the cutting angle before operation in close to zero is detected by obtaining the points P1 and P2 at which the main force component cutting resistancesIa and IIa accord with the back force component cutting resistancesIa and IIb or by obtaining the cutting edge angle before operation at which the degree of variation of the back force component cutting resistances IIa, IIb and IIIb becomes the maximum. The revolution angle of a rotary table 11 which guides and holds the holding base 13 of a tool 15 is controlled by said detection signal. Thus, the tool can be set automatically to the angle at which the cutting edge angle before operation becomes nearly zero.
