Measured Cutting Forces in the Turning of Prismatic Parts at Different Spindle Speeds and Side Cutting Edge Angles
Özet
This study attempted to measure three cutting force components simultaneously for prismatic parts and determine the force-time characteristics until face turning was finished. A calibrated dynamometer was used in the turning experiments. The experiments for the aluminum alloy and brass workpieces were performed at different side cutting edge angles (SCEAs) for three different spindle speeds. The turning finishing processes of the prismatic parts were also monitored successfully. The cutting speed had a remarkable effect on the quality of data acquisition, but the SCEA did not. The scatter width of all forces increased with decreasing cutting speed, but the SCEA was not effective. Three forces generally exhibited familiar characteristic with increment in the SCEA for aluminum and brass workpieces. Furthermore, the cutting force amplitudes were perceived to be higher in cylindrical machining regions than impact machining regions. The F e and F r indicated similar self-trends for both metals during total machining processes.
