Problems solved by technology

By smoothing the curved surface, the occurrence of the folded tool path can be effectively avoided, but the surface smoothing operation is complicated, difficult, and difficult to realize; by reducing the tool radius, the generation of the folded tool path section can also be avoided, but the processing efficiency will be reduced

Abstract

The invention provides a tool path fairing method for aircraft engine blade machining, equipment and a readable storage medium. The method comprises the steps of recognizing feature points of an inflection tool path segment in the process of aircraft engine blade machining; and deleting the feature points of the inflection tool path segment after the recognition of the feature points of the inflection tool path segment is completed. According to the invention, post-processing of inflection can be automatically recognized and processed, and the inflection tool path segment is automatically deleted, smoothened and the like before the tool path generated by the CAM is converted into an NC code. The manufacturing efficiency and quality of the tool path are greatly improved, and the problems that the machine tool shakes in the operation process of the machine tool, the stability of the machining state is affected, and the machining quality is reduced are solved. The machining stability andthe machining quality are improved, the processes of manually and carefully checking the tool path, judging the inflection tool path segment and deleting the inflection tool path segment are reduced or not needed any more, and the situation that the omission is caused due to the fact that the inflection tool path area is too small is completely eradicated.

Description

technical field [0001] The invention relates to the technical field of aircraft engine blade processing, and relates to a tool track smoothing method for aircraft engine blade processing, equipment and a readable storage medium. Background technique [0002] Aircraft engine blades have complex surface characteristics. Foreign advanced multi-coordinate CNC machine tool manufacturers and professional impeller and blade manufacturers have also launched professional software packages dedicated to impeller and blade CNC machining, such as the STARRAG program of the American STARRAG company, the American Concepts NREC's MAX-PAC software package (including MAX-5, MAX-AB and MAX-SI impeller processing software) and CCAD / comig impeller design software, Swiss LIECHTI TurboSoft software, Italian "C.B.Ferrari" (Ferrari) company TECNOSOFT (TS30, TS50, TS80 series) software, Swiss Starragheckert (starrag-heckert, Starragheckert) RCS software, etc., these special software make full use of ...
