Abstract: A model for the plastic deformation that occurs in metal cutting, based on dislocation mechanics, is presented. The model explains the fundamental deformation structure that develops during ...

Abstract: The process of large strain plastic deformation, such as commonly found in the machining process, has been investigated by transmission and scanning electron microscopy techniques. The lamella-shear ...

Abstract: The examination of the surface morphology of copper, aluminum, and steel chips produced by standard shop machining processes through the use of scanning electron microscopy has led to a more ...

Abstract: Experimental studies of plastic deformation produced during metal cutting have shown that a dynamic equilibrium is established between strain hardening and recovery during chip formation. ...

Abstract: A quick stop device (QSD) was designed for use in orthogonal machining and rubbing experiments. QSD’s are used to obtain chip root samples that are representative of the deformation taking ...

Abstract: Different chip separation criteria for the FEM simulation of machining were examined. Criterion based on distance between the tool tip and the node located immediately ahead, criterion based on ...

Abstract: LINEX is a friction actuated, continuous extrusion process for metals. It is fundamentally a linear continuous extrusion process using two-sided gripping of feedstock with the opposed sides being ...

Abstract: This paper describes the use of decouplers within an integrated manufacturing cell operating in a Just-In-Time (JIT) environment. The operation of a cell and the function of decouplers are ...
