Method for automatically calculating coordinates of workpiece symcenter of numerically-controlled machine tool

Abstract

The invention relates to a method for automatically calculating coordinates of a workpiece symcenter of a numerically-controlled machine tool. The method comprises the following steps of step 1, fixing a workpiece symmetric axis in the manner of being parallel to the X axis or the Y axis of machine tool coordinates; step 2, mounting a photoelectric edge finder on a main shaft of the machine tool; step 3, respectively finding the coordinate positions O1, O2, O3 and O4 of a workpiece on symmetric position boundary points in the directions of the X axis or the Y axis by the edge finder; step 4, calculating a central point coordinate value OX which is equal to (X1+X2) / 2 and a central point coordinate value OY which is equal to (Y3+Y4) / 2, and taking the OX value and the OY value as the X value and the Y value of the original point of a workpiece coordinate system. The coordinates of the workpiece on symmetric position boundary points are automatically found by using the edge finder arranged on a main shaft of the machine tool, intelligent calculation on the workpiece symcenter is realized by a machine tool operation system, the setup of the original point of the workpiece coordinate system in the XY plane is finished, and the occurrence of numerical value reading error, calculation error and input error caused by human factors is avoided.

Description

technical field [0001] The invention relates to a method for automatically calculating the symmetrical center coordinates of a workpiece by a numerically controlled machine tool. Background technique [0002] CNC machine tools must first establish a correct workpiece coordinate system before processing parts to process qualified products. Among them, the symmetrical center point of the workpiece is often used as the origin of the workpiece coordinates. At present, for CNC machine tools without the function of intelligently calculating the symmetry center of the part to establish the workpiece coordinate system, in the operation process of setting the workpiece symmetry center as the origin of the workpiece coordinates on the XY plane, it is necessary to manually read the coordinate data, calculate and input the data, etc. operate. It is easy to cause numerical reading errors, calculation errors, and input errors caused by human factors, and it is difficult to find in the ea...

Problems solved by technology

It is easy to cause numerical reading errors, calculation errors, and input errors caused by human factors, and it is difficult to find in the early stage of processing. It needs to be detected after semi-finishing or finishing processing. For complex structures, conventional detection tools cannot detect , unable to find errors, resulting in unqualified processed products
