Abstract

The invention provides a workpiece machining method and system based on on-machine measurement. The workpiece machining method comprises the following steps that geometric data of the machining surface of a workpiece are measured in an on-machine measurement mode, according to the geometric data and a preset ideal workpiece model, registration adjustment is carried out on the geometric data to obtain geometric registration data of the machining surface, compensation correction is carried out on a numerical control machining program of the workpiece according to the geometric registration data,and the workpiece is machined by utilizing the numerical control machining program which is subjected to compensation correction. According to the scheme, the workpiece can be subjected to self-adaptive machining on the basis of workpiece geometric dimension data measured on-machine, so that the qualified rate and the machining efficiency of the machined workpiece are improved.

Description

technical field [0001] The invention relates to the field of numerical control machining, in particular to a workpiece processing method and system based on on-machine measurement. Background technique [0002] At present, there are a large number of large, complex and difficult-to-process parts in aerospace, automobile, ship and other fields. During the processing of such parts, due to factors such as processing deformation, imprecise clamping, tool wear, uneven allowance, and changes in equipment load, the pass rate and processing efficiency of the parts are often low. With the rapid development of digital measurement technology, the three-dimensional digital information of the processing state of the workpiece (that is, the part) can be obtained by using certain on-machine measurement technology, and the machine tool can adaptively change the processing state according to the measured processing state of the workpiece through adaptive processing technology. Compared with...
