ABSTRACT: Increasing the productivity and the quality of the machined parts are the main challenges of manufacturing industries. This objective requires better management of the machining system. Increasing the productivity and surface quality of the machined parts are the important challenges of different manufacturing industries. The manufacturing industries are trying to decrease the cutting costs, increase the quality of the machined parts those are manufacture by different methods and machine more hard and difficult materials. Machining efficiency is improved by reducing the machining time with high speed machining. In this literature authors have to analyzed machining of hard and soft materials, and soft and abrasive materials used in turning, coating materials for cutting tools, wear observed during turning operations, surface finish of the machined work piece, cutting force and temperature measurement between tool and work piece. Optimization of cutting parameters is valuable in terms of providing high precision and efficient machining. So an attempt is made to optimize machining parameters using coated tools and uncoated tool inserts. This study will help machining professionals cutting parameters in order to minimize cutting time, and produce better surface finish under stable conditions.

Keywords: Hard materials, machining, tool inserts, CVD and PVD coating methods, optimize parameters.
