Testing method for machining capability of five-axis CNC machine tool in opening and closing corner area

Abstract

The invention discloses a test piece and a detection method for the processing ability of the opening and closing angle area of ​​a five-axis numerical control machine tool. The conical ring at the center of the upper surface of the rectangular base; the rectangular base and the conical ring of specimen A and specimen B are the same size, but the end of the conical ring of specimen A with a larger end surface area is connected to the rectangular base, The end of the conical ring of specimen B with the smaller end surface area is connected to the rectangular base. Compared with the NAS979 test piece of the prior art, only closed-angle processing area exists, and the open-angle processing area is increased; compared with the "S"-shaped test piece, the present invention has a simple configuration and is easy to popularize and apply, because the processing track is circular The trajectory can meet the programming requirements by using the general CAM programming software; and it can better reflect the processing performance of the opening and closing angle area of ​​the machine tool.

Description

Technical field [0001] The invention belongs to the technical field of numerical control machine tools, and specifically 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 the CNC machine tool determines the machining accuracy of the parts, so detecting the source of error and improving the machining accuracy of the machine tool are the key aspects of machine tool acceptance. The prior art mainly aims at the geometric accuracy, positioning accuracy, and repeated positioning accuracy of the machine tool. The inspection item is single, and the inspection process is static inspection. In the machine tool dynamic accuracy acceptance, the standard test piece trial cutting method is usually used f...
