Embodiment Construction
[0061] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0062] Such as Figure 1-5 shown.
[0063] A comprehensive detection method for dynamic and static errors of a five-axis linkage machine tool, the implementation process is as follows figure 1 As shown in Fig. 1, while the machining accuracy of the machine tool to be tested is tested, the position information of each axis in the machining process of the machine tool is obtained through the monitoring of the position loop signal, and the discrete position sequence that is only affected by the dynamic error in the machining process of the machine tool is obtained; through some matching algorithms The mapping set of the discrete position sequence on the theoretical machining trajectory is established, and then the tool position error and direction error caused by the dynamic error along the machining trajectory are analyzed and calculated. Detec...

The invention discloses a five-axis linkage machine tool dynamic and static error comprehensive detection method. The five-axis linkage machine tool dynamic and static error comprehensive detection method is characterized in that when accuracy detection is carried out on an accuracy detecting piece machined through a five-axis linkage machine tool, all feeding shaft actual movement positions of the machine tool in the machining process are monitored and analyzed, and dynamic errors are obtained; detection analysis is carried out on the actual molding outline face of the accuracy detecting piece, and actual errors are obtained; and the actual errors are coupling of the dynamic errors and static errors, the actual errors are decoupled, and static error distribution within the machining spacescope of the detecting piece is obtained. By means of the five-axis linkage machine tool dynamic and static error comprehensive detection method, through machining and detecting of the accuracy detecting piece, dynamic error and static error distribution along the processing track can be simultaneously obtained, five-axis linkage machine tool dynamic and static error comprehensive detection is achieved, and reference and basis are provided for error comprehensive compensation.
Description
technical field [0001] The invention belongs to the technical field of numerical control machine tools, in particular to a processing technology for free-form surfaces and complex cavities in high-end equipment such as aircrafts and precision molds, and in particular to a comprehensive detection method for dynamic and static errors of a five-axis linkage machine tool. Background technique [0002] Five-axis linkage machine tools are widely used in high-end manufacturing fields such as aerospace and precision molds due to their excellent performance in processing complex free-form surfaces and complex cavities. Machine tool errors can be divided into dynamic errors and static errors according to their time-varying characteristics. When the machine tool is running under stable conditions (temperature, load, etc.), the dynamic error is mainly the trajectory error caused by the single-axis following error coupling, and the static error mainly refers to the geometric error caused...
