Abstract

This research is primarily aimed at the investigation of ultra precision cutting for the electroless nickel plating process. The electroless nickel plating process and subsequent heat treatment were adjust so that samples with three different phosphorus contents (5.5, 8.5 and 12.0 wt%); therefore, different microstructures and hardnesses were obtained. All samples were treated by the heat treatment conditions at 373, 473, 573 and 673K from 1to 3 hours. The conclusion drawn from this work is that electroless nickel plating for ultra precision cutting should contain at least an amorphous structure to obtain a high quality machined surface. Also, the nickel phosphorus plating material in heat treatment at 473K for 2hours is lightest damage for machined surface layer. The chip profile of ultra precision cutting appeared to have a lamellar structure for an amorphous structure
