Abstract

PURPOSE: To provide an automatic cutting control device for tool on a double eccentrical shaft designed capable of relatively turning inner and outer shafts, which constitute a machine tool's main shafts, by a required angle θ simply by giving an instruction directly to a tape as to an amount of cutting of a tool T.
CONSTITUTION: An outside main shaft So and an inside main shaft Si with their respective rotation centers O1, O2 given eccentricity by e are supported on the shafts, and the shaft Si is provided with a tool fit-in hole H. When the blade tip of a tool T is signified by P1 and the main shaft Si is rotated by an angle θ, an amount of change of the blade tip P in the radial direction, which is an amount of cutting T, is expressed as a difference between O1P1 and O1P2. This difference is detected and used as a control signal for controlling a relative angle θ of the inner and outer main shafts of the dual eccentricity mechanism. In this manner, a machine tool becomes able to be utilized for plural processing stages without tooling change.
