The main objective of this paper is to arrive at the optimum grinding conditions that will minimize surface roughness and maximize metal removal rate when grinding AISI 1040 steel materials. LITERATURE REVIEW

MoreGrinding is a material removal and surface generation process used to shape and finish components made of metals and other materials. The precision and surface finish obtained through grinding can be up to ten times better than with either turning or milling. Grinding employs an abrasive product, usually a rotating wheel brought into

MoreDec 09, 2005· If one of these curves turns to be a straight line, it must be the generatrix of the grinding cone. Thus, the grinding parameters are determined by a set of three generatrices. Then, the measurement method and data processing procedure are proposed. Its validity is assessed by measuring a sample with given parameters.

Moretakes the following input processes parameters namely work speed, number of passes, wheel speed and depth of cut. The main objective of this paper is to arrive at the optimum grinding conditions that will minimize surface roughness and maximize metal removal rate when grinding AISI 1040 steel materials. LITERATURE REVIEW

MoreNg et al. [7], [8] scaled the manual grinding parameters to robotic grinding platform by building a depth pixel model and a material removal model. Qi and Chen [3] designed a prediction model based on the average cutting depth of abrasive grains to predict the surface roughness for robotic grinding, where the grinding belt wa s fixed on the

MoreDec 08, 2016· 3. Grinding methods differ in how parts are fed through the machine. The primary difference between the two most commonly used methods of centerless grinding is in how the workpieces are fed through the machine. Through-feed grinding is typically used for parts with consistent roundness across the length of the part. In this method, the

MoreThe definition of grinding parameters such as infeed speeds and switch-over points requires considerable experience and ultimately decides the workpiece quality and the productivity of the machine. Ex-perience has shown that only a very few operators take the trouble to calculate grinding parameters based on standard formulas. The result

Moreemployed to analyze the influence of grinding parameters on material removal rate during grinding process. The purpose of the analysis of variance (ANOVA) is to investigate which design parameters significantly affect the quality characteristic. This procedure eliminates the need for repeated experiments, saves time and conserves the material
