Five-coordinate numerical control machining cutter path changing method

Abstract

The invention relates to a five-coordinate numerical control machining cutter path changing method, which comprises the following steps: firstly establishing a table of device data before and after change, then constructing post-processing methods of the two devices for each machine tool before and after the change between a cutter path described in a cutter position document and a machining cutter path based on the characteristics of the devices, carrying out inverse computation on the input machining cutter paths to obtain a linear shaft programming cutter position point, necessarily constructing an anti-tracking rotation processing method, constructing a corresponding relationship between coordinate systems of the devices before and after the change, constructing a method for mutually changing the machining cutter paths between the two machine tools based on the corresponding relationship between the coordinate systems, and finishing the change of the machining cutter paths based on the constructed method for changing the machining cutter paths of the machine tools. The method improves the preparation efficiency of the machining cutter paths in the process of changing components / devices, and reduces the workload.

Description

technical field [0001] The invention relates to numerical control machining technology, in particular to a numerical control machining tool path construction method for a specific machine tool. Background technique [0002] The fans, compressors, and turbines of new high-thrust ratio high-performance aeroengines generally adopt the integral blisk structure. Compared with the traditional blade and disc assembly structure, the integral blisk saves the tenons, tenons and locking devices, avoiding the airflow loss of the tenons; at the same time, it greatly reduces the number of parts and reduces the weight of the structure. The integral casing is the key technology for weight reduction of high-performance aero-engines. The use of the integral casing structure can greatly reduce the number of parts, reduce the structural weight, and improve engine efficiency. The overall blisk is similar to some impeller parts. Because of its openness, the open blisk is open, and the traditiona...
