Sažetak
Machining system VBS was constructed and built at the Faculty of Mechanical Engineering in Sarajevo, for investigations of the phenomena in high speed milling. Since the requests for high speeds and accelerations of the main spindles and the transmitters for the feed motions require specific design and mechatronic solutions, this paper presents the selection of optimal design variety of components integrated in machining system VBS. The investigation of the effect of the cutting parameters on the cutting forces during high speed face milling (range of cutting speed from 750 m/min to 3000 m/min) was conducted on the machining system VBS. Investigations were carried out on hardened alloy steel EN 10083-3 (41Cr4). The results show that cutting force FR decreases by increasing cutting speed. Also the investigations show that the feed per tooth has significant effect upon the values of cutting forces. This paper further presents the mathematical model for calculating cutting force in high speed cutting. Experimental results are compared with calculation results.
