Five-axis numerical control machine tool open-angle and close-angle area machining capacity detecting test pieces and method

Abstract

The invention discloses five-axis numerical control machine tool open-angle and close-angle area machining capacity detecting test pieces and method. The test pieces include the test piece A and the test piece B. The test piece A and the test piece B each comprise a rectangular base and a conical ring arranged at the center of the upper surface of the rectangular base. The rectangular bases of the test piece A and the test piece B are the same in size, and the conical rings of the test piece A and the test piece B are the same in size. The end, larger in end face area, of the conical ring of the test piece A is connected with the corresponding rectangular base, and the end, smaller in end face area, of the conical ring of the test piece B is connected with the corresponding rectangular base. Compared with NAS979 test pieces in the prior art, an open-angle machining area is added to a close-angle machining area; compared with S-shaped detecting test pieces, the test pieces are simple in structure and convenient to apply and popularize; due to the fact that the machining track is a circular track, the programming requirement can be met by achieving postposition through universal CAM programming software; the machining performance of a machine tool for machining open-angle and close-angle areas can be better reflected.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools, and in particular relates to a test piece and a detection method for the processing capability of the opening and closing angle area of ​​a five-axis numerical control machine tool. Background technique [0002] Five-axis CNC machine tools are mainly used in the processing and manufacturing of complex surface parts such as molds and aerospace. The accuracy of CNC machine tools determines the machining accuracy of parts, so detecting error sources and improving the machining accuracy of machine tools are the key links in machine tool acceptance. The existing technology is mainly aimed at the geometric accuracy, positioning accuracy and repeat positioning accuracy of the machine tool, and the detection items are single, and the detection process is static detection. In the dynamic accuracy inspection of machine tools, the standard test piece test cutting method is usually u...
