V-shaped groove forming machine and its control method

DETAILED DESCRIPTION With these problems in mind, therefore, it is the primary object of the present invention is to provide a V-shaped groove forming machine which can easily form V-shaped grooves on one surface of a plate material and its control method.
The second object of the present invention is to provide a V-shaped groove forming machine which can start and end V-shaped groove forming operation from or at any given position, and its control method.
To achieve the above-mentioned object, the V-shaped groove forming machine according to the present invention basically comprises: (a) an X-axis slider disposed opposing one surface of a plate material mounted on a work table and reciprocably movable in an X-axis direction; (b) a Z-axis slider supported by said X-axis slider and reciprocably movable in a Z-axis direction; and (c) a cutting tool mounted on said Z-axis slider to form a V-shaped groove on one surface of the plate material.
Further, the method of controlling a V-shaped groove forming machine according to the present invention basically comprises: (a) controlling an X-axis direction stroke of an X-axis slider disposed over a work table for supporting a plate material so as to be reciprocably movable in an X-axis direction; (b) providing a cutting tool for forming a V-shaped groove on one surface of the plate material; (c) controlling a Z-axis direction stroke of a Z-axis slider supported by said X-axis slider so as to be movable up and down; and (d) controlling a cutting start position, a cutting end position, and a cutting depth of the cutting tool relative to the plate material in order to form a V-shaped groove on the plate material in the X-axis direction.
