Abstract
Polycrystalline cubic boron nitride (PCBN) cutting tools have enabled large-scale industrial hard machining owing to their high hot hardness and wear resistance. Experience clearly shows that tool requirements vary depending on the presence and severity of interrupts in the workpiece. The interrelationships between workpiece interruption parameters and tool wear and performance are assessed using a programme of continuous, semi-interrupted, and interrupted hard machining tests. A hypothesis for observed variations in wear behaviour between different PCBN grades and test conditions is developed on the basis of detailed tool wear scar analyses.
