Intelligent five-axis control system and method thereof

Abstract

The invention discloses an intelligent five-axis control system and a method thereof, and belongs to the technical field of machine tools. The intelligent five-axis control system comprises an upper computer, a lower computer, an execution system, a power supply system module and a manual operation control panel, the upper computer controls the execution system to work through the lower computer, the upper computer receives coordinate points, measured by the in-situ measurement system, of the surface of a workpiece through the lower computer, the coordinate points are reconstructed into a workpiece model in the current state through a built-in program, the workpiece model in the current state is compared with a workpiece design model before machining, the machining deviation and the machining allowance of the workpiece in the current machining state are obtained according to the comparison result, compensation machining or stopping machining is conducted according to the machining deviation, and a manual operation control panel is used for controlling start and stop of a minimum quantity lubrication system and an ultrasonic longitudinal torsion milling system of the five-axis machine tool. According to the intelligent five-axis control system and the method, the five-axis linkage motion control function is achieved, and the system and method have the remarkable advantages of openness, expandability and portability.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to an intelligent five-axis control system and method. Background technique [0002] At present, for the high-precision machining of complex thin-walled parts in the aerospace field, multi-axis milling is mostly used, which puts forward higher requirements for the comprehensive performance of multi-axis milling equipment. The most important thing is to realize the automation, precision and integration of processing and manufacturing. In the application process of the existing CNC system, the tool trajectory path planning of the parts to be processed is generally adopted offline, and the tool position is post-processed into a processing program code that the machine tool can recognize, and then the processing program is imported into the CNC system. .

Problems solved by technology

[0003] When complex thin-walled parts in the aviation field are processed by multi-axis milling, it is difficult to guarantee the processing quality and processing efficiency. When the processing environment requirements of the existing five-axis CNC machining center system change, such as data acquisition and signal monitoring during processing, etc. , it is difficult for researchers to carry out follow-up function development, which leads to poor processing adaptability of machine tools, and the inability to perform functional integration under specific processing requirements in specific occasions, resulting in cumbersome processing technology, increased time costs and reduced production capacity

[0004] In addition, the patent CN 201810440487.3 discloses a multi-axis linkage embedded numerical control system, which is difficult to realize online programming and post-processing of parts to be processed

Patent CN 201510831343.7 discloses a soft bus-based collaborative numerical control system, which cannot be integrated with multi-functions and cannot meet complex and changeable processing requirements
