Abstract
This paper presents an experimental investigation on chip deformation of the actual turning with actively driven rotary tool. The main purpose of the present work is to make clearly the effect of tool rotational speed and its direction upon the cutting force components, and the chip formation. In order to investigate the effect of tool rotation with a wide range of speed, the cutting tool is driven by the high speed motor of main spindle machine and its rotation is controlled by NC Programmable. The components of cutting force were measured using the piezoelectric force transducers of a force ring dynamometer. Experimental results show that the tool rotational speed can lead an increase in the dynamic inclination angle so that causes the helix angle and the pitch of chip were increased. This indicates the cutting mechanics changed from the orthogonal to the oblique cutting. It was also found that the tool rotational speed has a significant effect on the cutting forces. The resultant and tangential cutting forces decrease with increasing the tool rotational speed to certain value and then constant. The resultant cutting force of rotary tool was approximately 18% lower than the resultant cutting force recorded by the cutting with a non-rotating tool. The axial force increases with an increase in tool rotational speed in a certain speed range and then constant. Interestingly, the constant of the cutting forces as mentioned above along with the increase of the tool rotational speed was obtained at the dynamic inclination angle higher than 45deg. or the velocity ratio higher than 1.
