| Abstract in different language: | Poly-crystalline cubic boron nitride (PCBN) is the hardest material beside diamonds. Generally, so hard materials could not be machined by conventional machining technologies. For this purpose, advanced machining methods have been designed. Rotary ultrasonic machining (RUM) and laser beam machining (LBM) are included among them. This contribution investigate and compare these advanced methods during machining of PCBN. In experi-ments, a tool for friction stir welding (FSW) was manufactured. The main evaluated attributes was shape accuracy and dimension precision. When shape accuracy is not sufficient, welding process is negatively affected (lower tool life, improper weld parameters). And when dimensions of welding tool are different, it cannot be used for demanded sheet thickness. According to the performed experiments, RUM achieved good enough shape accuracy, but inadequate dimension properties. For LBM it was vice versa. |
