Research on Partition Segment Grinding Path Method of Aero-Engine Blade Based on Robot Group

Abstract

In this paper, the contour of aero-engine blade is fitted with spline curve, and the surface of the blade is segmented according to the fitted curve curvature. The mathematical model of continuous precession of blade surface grinding is established, and the algorithm of grinding path is studied. A program capable of simulating the surface grinding path of the blade was developed. 3-D reconstruction of the blade using the blade contour fitting curve was established. The experiments in this paper were performed on a system consisting of two robots, one of which was responsible for the blade space adjustment for its partition segment, and another robot responsible for the path of the grinding. This paper presents the experimental results data, analyzes the data, and selects some experimental condition parameters that can obtain better results.
