Problems solved by technology

Although these methods can evaluate the kinematic characteristics of the machine tool, there are the following problems: 1. The test method is single. Since the dynamic characteristics of the machine tool are often coupled by multiple factors, it is difficult to separate errors with a single detection method; Test machine dynamics during machining
These problems have brought difficulties to the test and analysis of the dynamic characteristics of the machine tool.

Abstract

Disclosed is a dynamic characteristic test analysis system of a numerically-controlled machine tool. The system includes two parts: a hardware part and a software part and is of a structure of a four-layer system. The four-layer system includes a hardware layer, a hardware management layer (PC), a machine tool test analysis layer (PC) and a database layer (work station). The hardware layer is connected with input of the hardware management layer (PC). Output of the hardware management layer (PC) is connected with input of the machine tool test analysis layer (PC). Output of the machine tool test analysis layer (PC) is connected with input of the database layer (work station). The hardware layer belongs to the hardware part. The hardware management layer (PC), the machine tool test analysis layer (PC) and the database layer (work station) belong to the software part. A plurality of test methods are provided so that construction of a test platform is facilitated, test error is reduced and test precision is improved.

Description

technical field [0001] The present invention relates to the technical field of performance evaluation of numerical control machine tools, in particular to a dynamic characteristic test and analysis system of numerical control machine tools Background technique [0002] Due to its high degree of automation and advanced technology, CNC machine tools have become key equipment in production, especially for processing parts with many varieties and small batches, complex structures and high precision requirements, CNC machine tools play an irreplaceable role. As the mother machine of industrial equipment, the dynamic characteristics of CNC machine tools will directly affect the quality of processed workpieces and the performance of industrial products. Therefore, the evaluation of the dynamic characteristics of CNC machine tools has always been the focus of machine tool manufacturers. [0003] So far, many machine tool manufacturers and users have used circular motion such as bal...
