Optimum Diameter and Position of a Fly Cutter for Milling 0.45 C Steel, 195 BhN and 0.4 C Steel, 167 BhN at Light Cuts

Abstract

Selection of cutter diameter and position of the cutter with reference to the work piece was studied to control the face-milling tool tip failure by fracture. The majority of the tests consisted of studies of the effect of angle of engagement and angle of disengagement on fractures at low and high cutting speeds. The result shows that the angle of disengagement is more critical than the angle of engagement. Favorable cutter diameters and positions based on empirical data are recommended to prevent fractures occurring at low and high cutting speeds. This report suggests that steel can be face-milled with titanium carbide and aluminum oxide tools using optimum setups as suggested by this study.
