Abstract

The material-removal process plays an important role in manufacturing industry. A thorough understanding of the complex action in chip formation is essential in order to lead to optimum selection of tools and machining parameters. This papers describes the development of a quick stop device (QSD) for use on a CNC lathe, that can be set up conveniently for experimental investigations. Using this device a cutting process and stopped as quickly as possible so that the observed deformation is close to that while actually machining. The device is based on the shear-pin concept of resisting the cutting forces during normal machining and freezing the cutting action when the shear pin is broken by the impact of a hammer. The material contained within the zones of chip and workpiece surface generation constitutes the "chip root". In order that the chip root should faithfully represent the geometrical and metallurgical configuration that exists under normal cutting conditions, instantaneous separation of the tool and workpiece should take place. As instantaneous separation requires infinite acceleration ( or deceleration) of ither the tool or the workpiece, this performance is physically impossible to achieve and some measure of deviation from the ideal must be tolerated.
