ROBOT ASSISTED STABILIZATION FOR FLEXIBLE WORKPIECES SUBJECTED TO HIGHLY INTERRUPTED CUTTING

Abstract

In many facets of industry, slender workpieces are formed by means of milling processes. These workpieces are especially prone to experience harmful chatter vibrations, which limits quality and productivity. In this paper, a novel solution is proposed where a robotic arm is used to support the workpiece, improving its modal properties and reducing the occurrence of chatter. The paper presents some numerical, analytical and limited experimental results for improving the material removal rate using the robot assisted milling method for low radial immersion processes, such as finishing operations.
