Abstract

The invention provides a numerical control machine tool data management method. The method comprises the steps of collecting a real-time detection result of a workpiece machining process of a numerical control machine tool; performing quality evaluation on the machined workpiece to obtain quality evaluation information of the workpiece; inputting a real-time detection result and a quality evaluation information into a numerical control machine tool model, and analyzing the form and location tolerance and the surface roughness of the workpiece to obtain a workpiece error; adjusting operating parameters, dynamic precision and cutter parameters in a digital control program of the numerical control machine tool according to the workpiece errors; and enabling the numerical control machine tool to carry out secondary machining on the surface with the workpiece error so as to compensate the workpiece error.

Description

technical field [0001] The present invention mainly relates to the field of numerical control machine tool manufacturing, in particular to a numerical control machine tool data management system and method. Background technique [0002] High bypass ratio turbofan aeroengine is the main driving force of civil aviation technology. It must strictly abide by the airworthiness requirements of civil aviation in all aspects of product design, testing and production. Its main key components such as fan blades, turbine discs, and overall blades The processing quality requirements of discs, casings, etc. are extremely strict. Therefore, the CNC machining machine tools for its components must also meet the requirements of high precision, high performance, and high stability. At present, domestic high-end CNC machine tools still have a big gap with the CNC processing equipment in Europe and the United States in terms of their own geometric accuracy, position accuracy, thermal stability...
