Predictive modeling of surface roughness and tool wear in hard turning using regression and neural networks
In machining of parts, surface quality is one of the most specified customer requirements. Major indication of surface quality on machined parts is surface roughness. Finish hard turning using Cubic Boron Nitride (CBN) tools allows manufacturers to simplify their processes and still achieve the desired surface roughness. There are various machining parameters have an effect on the surface rough...

Abstract: Formation of a hybrid coating by the use of plasma nitriding and hard chromium electroplating on the surface of H11 hot work tool steel was investigated. Firstly, specimens were plasma nitrided at a temperature of 550 °C for 5 hours in an atmosphere of 25 vol. % H2: 75 vol. % N2. Secondly, electroplating was carried out in a solution containing 250 g/L chromic acid and 2.5 g/L sulp...
متن کاملTool Life, Wear Rates, and Surface Quality in Hard Turning
An on-going comparative study of wear rates and tool lives under varying cutting parameters is presented in this paper, along with results indicating the abilities and limitations of the hard turning process to produce finished surfaces with acceptable roughness and integrity. To date, the study has consisted of thirteen combinations of machining conditions. The tests were performed with four d...
