Fuzzy Linguistic Optimization on Surface Roughness for CNC Turning
Surface roughness is often considered the main purpose in contemporary computer numerical controlled CNC machining industry. Most existing optimization researches for CNC finish turning were either accomplished within certain manufacturing circumstances or achieved through numerous equipment operations. Therefore, a general deduction optimization scheme is deemed to be necessary for the industr...
متن کاملSimulation Approach for Surface Roughness Interval Prediction in Finish Turning
Existing simulation models used in predicting the surface roughness of a workpiece in finish turning are based on an ideal circular cutting tool nose profile. This leads to a single predicted roughness value for a given set of input parameters. In this paper, a simulation approach that considers the random tool nose profile micro-deviations as well as the tool chatter vibration to predict a rou...

This experimental workanalysis the influence of cutting conditions on surface roughness of EN-8during machining by CNC turning. Analysis of variance (ANOVA) is employed to investigate the influence of cutting speed, feed rate, and depth of cut and coolant type on surface roughness height Ra. The influence of the interaction of cutting speed, feed rate, depth of cut and coolant type on surface r...
متن کاملPrediction of surface roughness in ultraprecision turning using fuzzy logic
Ultraprecision turning is a manufacturing process used to generate a high surface roughness in precision components, and its input-output relationships are highly nonlinear. Surface roughness of a turned surface depends on the selection of cutting variables, such as cutting speed, feed and depth of cut. Realizing the fact that fuzzy logic controller (FLC) is a powerful tool for dealing with imp...
متن کاملAnn Based Prediction of Surface Roughness in Turning
Surface roughness, an indicator of surface quality is one of the most specified customer requirements in a machining process. For efficient use of machine tools, optimum cutting parameters (speed, feed and depth of cut) are required. Therefore it is necessary to find a suitable optimization method which can find optimum values of cutting parameters for minimizing surface roughness. The turning ...
