Problems solved by technology

The positioning accuracy of five-axis CNC machine tools needs to be corrected and compensated regularly. Laser interferometers are generally used for calibration and compensation. It is very simple to use laser interferometers to check the positioning accuracy of linear axes, and no additional fixtures are required. However, laser interferometers are used for rotation It is extremely difficult to check and correct the axis positioning accuracy
Most of the current zero point calibration schemes can only achieve the calibration of linear axes, but cannot achieve the calibration of rotary axes

Abstract

The invention discloses a zero calibration method of a five-axis numerical control machine tool. The method can be used for completing calibration through three steps that first, a return-to-zero calibration tool is installed; second, a linear shaft is subjected to return-to-zero calibration; and third, a rotating shaft is subjected to return-to-zero calibration. The calibration tool is simple instructural design, the linear shaft and the rotating shaft of the five-axis numerical control machine tool can be subjected to return-to-zero calibration, an actual rotating angle value of a C shaft is calculated according to the moving track so as to complete calibration, and in a similar way, return-to-zero calibration of an A shaft is achieved by utilizing a calibration surface c. The zero calibration method is simple in tool structure and simple in calibration step, a related calculating method is simple, and the problems in the prior art are well solved.

Description

technical field [0001] The invention relates to a method for calibrating a numerically controlled machine tool, in particular to a method for calibrating a zero point of a five-axis numerically controlled machine tool. Background technique [0002] A five-axis CNC machine tool means that there are at least five coordinate axes (three linear coordinates and two rotational coordinates) on a machine tool, and can be processed simultaneously under the control of a computer numerical control (CNC) system. Five-axis CNC machine tool is a kind of high-tech and high-precision machine tool specially used for processing complex curved surfaces. This machine tool system has great significance for a country's aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment and other industries. Heavily influential. [0003] However, accurate zero return of five-axis CNC machine tools is an important measure to ensure the machining accuracy of ...
