Title: Method for determining working standard point of workpiece and method for carrying out work by use of said standard point
Inventor: YAMAMOTO YUZO
IPC: B23C3/12
Filed: 1990-10-09
Abstract: PURPOSE:To enable automatic cutting by the use of specified working standard points by using as the working standard points a specified range among closed ranges formed by an X axis as well as the curved line of data calculated based on the measurement data of Y axis on the X axis at a surface position of a workpiece, both of which being cross with each other. CONSTITUTION:A tube 1 made from a steel plate and bent circular in section is provided with a welded bead part 2 and small projection parts 3 formed by sputtering. Working standard points are determined in the shape of this surface. Namely, the surface position of a workpiece is measured in three axes X, Y, Z, and smoothening data is obtained based on the measurement data of Y axis on an X axis. The smoothening data is then subtracted from the measurement data of the Y axis, and the range with the maximum area is specified by determination among those on the plus side on the X-Y plane formed by the X axis and the curved line of data obtained by subtracting the smoothening data from the measurement data of the Y axis, both of which being cross with each other. Furthermore, extremely small points on both sides of the specified range are determined and used as the working standard points. It is thus possible to carry out automatic cutting by the use of determined working standard points.
