    Notes: The finite element modeling and experimental validation of three-dimensional precisioncutting of 3J33 maraging are presented. The commercial software MARC applied for the finiteelement modeling is studied the effect of tool nose radii considering tool edge radius on theprincipal cutting forces and the temperature fields. The model employs an updated Lagrangianformulation. The friction between the tool and the chip is assumed to follow a modified Coulombfriction law and the adaptive remeshing technique is using for the formation of chip. The tool edgeradius significantly affects the cutting forces and the maximum temperature of the chip. Thesimulation results for tool with nose radius considering tool edge radius are compared withexperimentally measured data and found to be in good agreement

    Surface Roughness Prediction Based on Cutting Parameters and Nose Radius in Precision Turning (2007)

    Notes: In precision turning, the quality of surface finish is an important requirement formachined workpiece. Thus, the choice of optimal cutting parameters is very important forcontrolling the required surface quality. The focus of the present study is to find a correlationbetween surface roughness and cutting parameters (feed rate, depth of cut) and nose radius inturning 3J33 maraging steel, and to derive mathematical models for the predicted surface roughnessbased on both of cutting parameters and nose radius. The experimental design is carried out usingthe quadratic rotary combination design. The regression analysis shows feed rate and nose radiusinfluence surface roughness significantly. With F-ratio test the proposed model is adequate. Themethod could be useful in predicting roughness parameters as a function of cutting parameters andnose radius
