Machining with chamfered tools

It has been observed that both in continuous and interrupted turning, with the increase chamfer width, both the main cutting force and feed forces increases and the effect on the feed force is more significant. With the increase of chamfer angle, cutting forces increased but at the maximum chamfer angle, both main cutting force and feed force were low. The chip thickness was observed to decrease with increasing chamfer width. However the effect of chamfer angle on the chip thickness was insignificant. Shear angle increased with the increase of both width and angle of the chamfer.
