Abstract
A rotary cutting tool for forming a heat plate has a plurality of cutting blades arranged about a cutting tool body. The cutting edge profile of the rotary cutting tool has a lower radius portion and a middle convex portion. The lower radius portion has its center on the axis of the rotary cutting tool and the middle convex portion is defined by an inverse square curve of form Y=1/X2 with the vertical axis of the origin of the inverse square curve offset from the axis of the rotary cutting tool. X has values between 0.25 units and 4 units.
Claims6
A rotary cutting tool for forming a heat plate has a plurality of cutting blades disposed axially upon and circumferentially about a cutting tool body, said rotary cutting tool having a cutting edge profile comprising a lower radius portion and a middle convex portion, said lower radius portion having a center on a rotational axis of said rotary cutting tool, said middle convex portion defined by an inverse square curve of form Y=1/X2 wherein said profile has values of X between 0.25 units and 4 units and wherein a vertical axis of an origin of said inverse square curve is offset from said rotational axis of said rotary cutting tool by a maximum selected value of X and a horizontal axis of said origin of said inverse square curve is offset from a tangent of said lower radius portion of said rotary cutting tool by a value of Y at said selected value of X.
