Abstract

Abstract: How to generate the 5-axis onsite inspection path of the enclosed impeller with global-fairing advantage is a difficult task, due to its enclosed structure, long-narrow runner and high-bending blades. This paper defines four kinds of accessibility cones, and constructs the objective function of 5-axis onsite inspection path based on the spring model of adjacent inspection axes. The forward Euler-difference method is used to calculate the inspection directions. An enclosed impeller with 5 blades is used to calculate the accessibility cone, optimize the inspection directions and generate the global-fairing inspection paths without interference. The experiments demonstrate the feasibility and validity of the proposed method.

Key words: enclosed impeller, onsite inspection, accessibility cone, inspection-axis direction, elastic potential energy
