Method for correcting machined workpiece angles

Abstract

The invention discloses a method for correcting machined workpiece angles. The method includes the following steps that (1), a machined workpiece is preliminarily set right at the position of a working table-board, and the workpiece is tightly clamped; and (2), a machine tool controller controls a measuring head to detect, (2.1), a coordinate system is established, and an X-axis and a Y-axis of a working table of the machine tool are rapidly positioned to a first alignment point; (2.2) measuring head length compensation is executed, and a Z-axis is positioned to a position which is 30mm away from the workpiece; (2.3) the Z-axis approaches to a position which is 7mm away from the workpiece at a low speed, the first alignment point measurement is started, and when the alignment returns to a safety point, alignment data is automatically recorded in a Z compensation of the coordinate system; (2.4) the Z-axis is rapidly movably positioned to a second alignment point; (2.5), the Z-axis approaches to a position which is 7mm away from the workpiece at the low speed, the second alignment point measurement is started, and when the alignment returns to a safety point, the alignment data is automatically recorded in a Z compensation of the coordinate system; and (2.6), the Z-axis returns to a tool changing point, a distance difference is converted to angles to be compensated to the coordinate system, and the correction is finished. The method for correcting the machined workpiece angles is convenient, rapid and high in accuracy.

Description

technical field [0001] The invention relates to a method for correcting the angle of a workpiece. Background technique [0002] The workshop needs to correct the angle of each workpiece when processing many products. The traditional processing method is to manually use the dial gauge to correct: [0003] 1. The operation needs to move back and forth to compare the distance between the two ends in the depth direction, and turn the rotating shaft to make the distance between the two ends gradually approach until the readings of the dial indicator at both ends are consistent. [0004] 2. After calibration, manually enter the corresponding calibration value in the coordinate system. [0005] 3. Start the processing program to process the workpiece. [0006] Manual correction has several disadvantages: [0007] 1. Manual calibration is a waste of time, and it takes 3 to 5 minutes to correct a workpiece on average. (The time for unskilled ones is longer, which affects the sta...
