Abstrakt: High-precision slot grinding was carried out on Mn-Zn ferrites to investigate the chipping mechanism and optimum slotting condition by measuring the chipping size at the slotted edges. The slot grinding was performed using a high-precision slicing machine with an air spindle and different type of 2mm wide diamond wheels. The size (width, length) of all chippings was measured by a specially designed form tracer with a knife edge pickup. Grinding forces were also measured. It is evident that chipping size depends on removal per grain and some ductile fracture modes are observed at lower removal rate ranges. Therefore, chipping size can be reduced largely by decreasing removal per grain.
