In a method of forming an offset configuration for a cutting tool which is used to machine a workpiece under the control of a numerical control device, both in the case where a cutting tool having first and second edges on both sides which have nose Rs, respectively, are used in such a manner that the cutting tool is moved horizontally and vertically with respect to a workpiece rotating, and the first edge is used when a machine configuration increases in vertical coordinate, and the second edge is used when a machining configuration decreases in vertical coordinate, and in the case where a cutting tool having first and second edges on both sides which have nose Rs, respectively, and provide a predetermined inclination angle .theta. is used in such a manner that the tool is moved horizontally and vertically with respect to a workpiece rotating, and the first edge is used when the inclination angle, in a vertical direction, of a machining configuration is smaller than the inclination angle .theta., and the second edge is used when the inclination angle, in a vertical direction, of a machining configuration is larger than the inclination angle .theta., the offset configuration is formed with the center of the tip of one of the edges of the cutting tool as the control center according to the final machining configuration, with the results that the machine tool operating under the control of a numerical control device can machine a workpiece with a cutting tool having right and left edges, with the machining time reduced as much.
A method of forming an offset configuration in the case where a tool having first and second edges on either side thereof, which have nose radii, respectively, are used in such a manner that the tool is moved horizontally and vertically with respect to a rotating workpiece, and said first edge is used when a machining configuration increases in vertical coordinate, and said second edge is used when a machining configuration decreases in vertical coordinate, wherein the method further comprises the steps of
A method of forming an offset configuration in the case where a tool having first and second edges on either side thereof, which have nose radii, respectively, and which define a predetermined inclination angle .THETA. is used in such a manner that said tool is moved horizontally and vertically with respect to a rotating workpiece, and said first edge is used when the inclination angle, in a vertical direction, of a machining configuration increases is smaller than said inclination angle .THETA., and said second edge is used when the inclination angle, in a vertical direction, of a machining configuration is larger than said inclination angle .THETA. wherein the method further comprises the steps of
