Abstract:
A method of manufacturing a machining tool, comprising the steps of:forming a powered metal into a preformed shape which approximates the desired shape of the machining tool byforming a first powdered metal, comprising a first alloy, into a first preformed shape which has an outer surface that approximates a first portion of the desired shape of the machining tool and a hollow interior, wherein the thickness of the first performed shape approximates 1/8 inch (0.318 centimeters);forming a second powdered metal, comprising a second alloy, to fill at least a substantial portion of the hollow interior of the first powdered metal shape;bonding the powdered metal in the preformed shape wherein the bonding step bonds the first and second powder metals, respectively, each to itself and at their interface to each other; andmachining the preformed shape to achieve the desired shape.
