Complex curved surface robot abrasive belt variable feeding self-adaptive grinding method and equipment

Abstract

The invention discloses a complex curved surface robot abrasive belt variable feeding self-adaptive grinding method. The method comprises the following steps that a model of a to-be-machined curved surface is reconstructed; data of cutter contact points are acquired; the robot feeding speed of machining point positions is obtained according to the cutter contact data; and a machining code is generated and machining is conducted according to the machining code. The invention further discloses complex curved surface robot abrasive belt variable feeding self-adaptive grinding equipment applying the complex curved surface robot abrasive belt variable feeding self-adaptive grinding method. According to the complex curved surface robot abrasive belt variable feeding self-adaptive grinding method, a robot contact wheel can be attached to the blade profile in the optimal posture, different robot feeding speeds can be further distributed according to the allowance value information of all the machining point positions, and therefore the accurate removal amount of the allowance of all the machining point positions can be guaranteed, and therefore, the self-adaptive grinding machining precision and quality of the complex curved surface part robot can be comprehensively improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for self-adaptive grinding of complex curved surface robotic abrasive belts with variable feed. The present invention also relates to a device applied to the above-mentioned method for adaptively grinding complex curved surface robotic abrasive belts with variable feed. Background technique [0002] High-performance components in the aerospace field mostly involve common features such as difficult materials to process, complex curved surface structures, and high processing quality requirements. Taking the machining of the blisk as an example, the curvature of the thin-walled complex surface changes drastically and the machining allowance is unevenly distributed. Due to the characteristics of the elastic contact of the abrasive belt grinding, if the trajectory planning based on the allowance distribution is not carried out, after grinding The cross-sectiona...
