SIMPLE PLOTTER
Document Type and Number:
Japanese Patent JPH04237304
Kind Code:
A
Abstract:
PURPOSE:To simplify the positioning work of an object to be worked on the working orgin of a working program in a simple plotter. CONSTITUTION:A control device 3 for controlling a table 1 and a tool spindle 2 based upon a working program and a displacement variable calculating device 4 are connected to a working machine provided with the table 1 for mounting a base A and the tool spindle 2 opposed to the table 1. The device 4 finds out the center (working origin) O2 of the base A from the positions of two points P1, P2, on the base A mounted on the table 1 and then finds out the displacement distances x3, y3 of the base A from the center O1 of the table 1 based upon the positions of respective points. The plotting shape of the working program can be allowed to coincide with the working face of the base A by currecting the working origin of the working program by the found displacement distances.
