Abstract

The invention provides a CNC (Computerized Numerical Control) machine tool temperature error compensation estimation method and device. The method comprises the following steps of obtaining the cumulative movement amount of a target work table corresponding to a target shaft in a (n+1)th period, wherein the n is a positive integer; determining a cumulative heating value in the (n+1)th period according to the cumulative movement amount; determining a current deformation error according to the cumulative heating value and a deformation error coefficient calibrated in advance; performing positionerror compensation on the current deformation error on the basis of the current first position of the target work table and the second position of the target work table during the calibration of thedeformation error coefficient; and obtaining an error value used for temperature error compensation. By using the method and device provided by the embodiment, the cost of the CNC machine tool is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for estimating temperature error compensation of a numerically controlled machine tool. Background technique [0002] As we all know, the temperature compensation algorithm of CNC (Computerized Numerical Control, CNC) machine tools has always been a difficult problem for the manufacturing industry to improve the machining accuracy. This is because ambient temperature or heat buildup from machining can cause parts of the machine to expand. The expansion range depends on the temperature, thermal conductivity, etc. of each machine part. Different temperatures can lead to changes in the actual position of the individual axes, which can negatively affect the accuracy of the workpiece being machined. These actual value changes can be counteracted by temperature compensation in order to always correctly compensate errors due to thermal expansion. In the pri...
