One method for creating broken chips in turning processes involves oscillating the cutting tool in the feed direction utilizing the CNC machine axes. Using computer simulations it is possible to combine the motion of the axes with the geometry of the

The use of oscillating CNC toolpaths has been shown to provide a reliable chip breaking alternative to conventional methods. This paper builds on that work by assessing the effect of the oscillating toolpaths on the temperature during the cutting pro

Machine-tool manufacturers have traditionally used position-feedback devices such as resolvers, encoders, Inductosyns, etc, to provide slide-displacement data to the control servo system. The location of the cutting tool and workpiece are thereby inf
