Ultra-High-speed Micro Machined Surface Integrity of Plastic Strain in Magnetic Abrasive Machining

Rui Wang, Joo Hyun Park, Lida Heng, Jae Won Choi, and Sang Don Mun
Abstract—An ultra-high-speed micro machining process is a micro-machining technique, which is used to minimize the surface roughness and change the precision morphology of the difficult-to-machined materials. Surface integrity is a very important process, which is used to evaluate the highly stress and the loaded components. It is important to evaluate the plastically deformed layers in the precision machined surface process. However, the typical plastic strains in the precision machined surface are significantly difficult to measure. In this paper, the ultra-high-speed micro machining equipment and the critical magnetic abrasive tool were applied in magnetic abrasive machining process. SUS 304 bars which are widely used in many applications were used as the cylindrical workpiece. The aim of this research is to explore a new technique for measuring the plastic strain in magnetic abrasive machining process and for investigating the effects of ultra-high-speed micro machined surface on the plastic strains and strain energy and to determine the residual strain in plastically deformed materials by analyzing the plastically deformed layer. The results concluded that the best improvements in the precision dimensional accuracy and precision surface accuracy were achieved at the ultra-high-speed of 80000 min-1 and the ultra-high-speed machining was not caused the impact of plastically deformed.

Index Terms—Ultra-high-speed, magnetic abrasive machining, recrystallization technique, surface integrity, plastic strain, surface accuracy, dimensional accuracy.
