Surface cutting parameters for improved surface finish by roughness of a material after turning is measured using acquiring minimum surface roughness in turning process portable surface roughness tester. Surface roughness is and to present various methodologies and practices that an important criterion to find the quality of a surface. It are being employed for the prediction of surface is an important response parameter. Surface finish can roughness. Surface roughness is one of the most be measured using simple surface roughness tester [3, commonly used criteria to determine quality of a turned 4]. surface. This literature review compiles different work In machining process various parameters are: presented on optimization of process parameters and Input Parameters: Cutting speed, Feed rate, Depth of concludes the most significant cutting parameters and cut, Insert radius, Cutting fluid, etc most frequently used optimization techniques for Output Parameters: Surface roughness, MRR, Tool improving surface finish The cutting parameters like wear, Cutting forces, MAZ, etc. Cutting speed, Feed rate, Depth of cut, Insert radius and Cutting fluid are taken into consideration. Surface engineering aims to achieve desired properties or characteristics of surface-engineered components Key Words: Turning process, Optimization Techniques, including: Surface Roughness, Taguchi Method Improved wear resistance; 1. INTRODUCTION Reduced friction energy losses; Improved mechanical properties, for example, Turning is a machining process used to obtain the enhanced fatigue life, hardness or toughness; desired dimension of round metal. The main target in Improved aesthetic appearance, etc. present industrial era is to produce low cost quality product with required dimensions in an optimum time. Therefore, the optimum cutting parameters are to be recognized first. In turning, the metal is in rotational motion (axially) and a cutting tool is used to shear away the undesired metals. This process requires lathe or turning machine, cutting tool, work piece and fixture [1]. The work piece is fixed in the machine chuck and is rotated at high speed. The cutting tool (insert) is fed in parallel to the axis of rotation as shown in Fig. 1. During this machining process the cutting parameters highly depends upon the work piece, cutting tool material, etc. These are determined by experience or machine catalogue. Surface roughness is a widely used attribute of product quality and in most cases a technical necessity for mechanical products. Achieving the desirable surface quality is of great importance for the functional behaviour of a part [2]. Thus the optimum selection of cutting parameters such as feed © 2017, IRJET

Factors influencing surface roughness in turning:
Cutting parameters i.e. feed, cutting speed and depth of cut
Vibration
Material of work piece
Rigidity of the system consisting of machine tool, fixture cutting tool and work
Type, form, material and sharpness of cutting tool
Type of coolant used
