- Abstract
Cubic boron nitride (CBN) and synthetic diamond (SD) belong to the hardest materials known. Materials of such hardness cannot be machined by conventional machining technologies. Therefore, advanced machining methods were designed. Advanced method of rotary ultrasonic machining (RUM) is especially suitable for machining the hard and brittle materials such as glass and ceramics. RUM is based on the abrasive removing mechanism of an ultrasonic vibrating tool with diamond particles on active part. The current contribution investigates machining of CBN and SD by the above-mentioned advanced machining method. Different types of machine tool loads are evaluated. The results are compared with the machine loads obtained in the machining of alumina ceramics, which is considered as one of the hardest ceramic materials. It is machined also by RUM. This is one of the first papers dealing with machine loads in the processing of ultra-hard materials.
