Design and Application of Macro and Micro-combined Mechanism for Textured Surface Machining

Abstract

Textured surfaces with excellent tribological properties have attracted extensive attention. However, it is very challenging to machine textured surfaces on ultra-smooth surfaces due to the difficulty of tool setting. In this paper, a macro and micro-combined mechanism is designed for machining micro-textures on ultra-smooth surfaces. A compliant tool holder is designed to solve the problem of precise tool setting. The static characteristics of the tool holder are evaluated by the compliance matrix method and finite element analysis. Then, the modals of tool holder are further analyzed by finite element analysis. Finally, the machining paths are simulated and four typical textured surfaces are machined on the developed prototype.
