Abstract

The invention discloses a test device for testing post-processing parts, which comprises a device body in the shape of a regular square prism, three sides of the device body are provided with inclined-plane holes, and the side surfaces not provided with the inclined-plane holes An inclined truncated cone is installed; the top surface of the device body is provided with a plane hole. Through the NC programming of different structural features in the test model, the corresponding tool position trajectory is obtained, and the NC program that can be recognized by the NC machine tool is formed after post-processing software processing and transformation. According to the comparison between the tool position trajectory of the NC program generated by the post-processing and the programming trajectory in the test model, the correctness of the conversion calculation results of the post-processing is verified.

Description

technical field [0001] The invention relates to the technical field of parts testing, in particular to a testing device and a testing method for post-processing parts testing. Background technique [0002] Post-processing is the process of converting the tool path file generated by the programming software into an executable NC file for the CNC machine tool, and it is an indispensable key process for connecting the machine tool and process programming. At present, the correctness of the post-processing results is mainly judged by comparing the conformity of the tool position trajectory in the processed NC file with the test model. Due to the lack of a standard test model to test and verify the post-processing, the usual test model contains incomplete structural features, and functions such as coordinate transformation, overtravel tool lifting, and cycle output cannot be fully verified during the post-processing process. Contents of the invention [0003] The purpose of th...
