Abstract: The scratches produced by single abrasive grains in overcut fly milling show that the transverse shape of a grain is closely approximated by an arc of a circle. This radius of curvature is ...

Abstract: The deformation mode of a thin tube subjected to an arbitrary time varying pressure pulse is in two phases: (i) during positive radial acceleration a zone of zero axial strain sweeps outwards ...

Abstract: The paper presents a theoretical analysis for estimating the abrasive particle velocity in air-abrasive jet using continuum approach applied to two-phase flow system. Subsequently a theoretical ...

Abstract: It is shown that the wear of single abrasive grains in a simulated grinding operation (over-cut fly milling) is governed by a thermally activated mechanism. The model adopted in this theoretical ...

Abstract: A simple model for tool (cathode) design for plane parallel electrochemical machining and electrochemical drilling has been proposed. Assuming the initial tool shape to be complementary to required ...

Abstract: It has been found that the shear strain acceleration governs the machining parameters like tool-chip interface temperature, shear angle, tool wear, etc. It is therefore speculated that microhardness ...

Abstract: A simple criterion for predicting the initiation of central burst in extrusion is proposed. The geometric conditions to avoid central bursting are predicted by using the proposed criterion under ...

Abstract: A viscoplastic model for extrusion is discussed which simultaneously predicts the deformation field, optimal die geometry, and plastic boundaries. The die geometry and plastic boundaries are ...

Abstract: A process analysis model to determine the limiting drawing ratio for the first draw as well as for redraws is presented considering the effects of normal anisotropy, co-efficient of friction, ...

Abstract: The paper presents a feature-based analysis of cold extrusion process for non re-entry shapes. Part drawing of the shape to be extruded is drawn using line, arc, circle, polyline and ellipse ...
