Numerical analysis of surface integrity in parallel turning Part A: Influence of cutting tool nose radius

摘要: Abstract Nose radius of a cutting tool is an important factor in finding the surface integrity turned parts. The current research work deals with numerical analysis residual stress generated during parallel turning using finite element method based software. Appropriate material model was used for parting chip from material. vital process variable especially turning. main motive to estimate influence nose on axial and circumferential stresses retained by machined surfaces. results revealed that increment radius, compressive nature along feed direction increases front rear tool. For all radii, raised rise speed. 0.5 mm 250 m/min speed 0.2 mm/rev, highest second 1696 MPa 1838 MPa respectively. Higher causes larger dead metal stagnation zone which turn higher stresses.
