Abstract

There are provided a first machining method in which a tool (TL) is fed a predetermined amount (d) in a center direction of a blank to cut into the blank, after which the tool is fed in a cutting mode by an amount (W) corresponding to groove width longitudinally of the blank to perform grooving, and a second machining method in which the tool (TL) is fed in the center direction of the blank to perform machining down to the groove bottom (GB), after which the tool is raised to perform grooving. Based on data indicative of the shape of the tool used, it is decided whether to perform grooving down to the designated groove bottom (GB) by repeating the first machining method or perform grooving to a designated groove width by repeating the second machining method.

Claims2

Dependent claims

An automatic programming method for creating an NC program for machining a blank, comprising the steps of:

storing a plurality of machining methods;
storing tool data identifying a tool to be used and including identification data which specifies one of said plurality of machining methods;
selecting a tool to be used;
selecting one of said machining methods based on said identification data;
creating data defining a tool path based on said selected machining method;
storing said tooling data as a collection of tool data for a number of tools in a tooling file including identification data;
and
in a case where grooving is performed by a predetermined grooving tool by repeating a first one of the machining methods, cutter angle AC and nose angle AN contained in tool shape data of said tool are both set to zero;
and
in a case where grooving is performed by a predetermined grooving tool by repeating a second one of the machining methods, cutter angle AC and nose angle AN contained in tool shape data of said tool are both set to non-zero, with the cutter angle and nose angle serving as said identification data.
