CHALLENGE Alliant TechSystems' ATK Ammunition & Related Products Group experienced a continuing product wear and component fit deficit with a critical munitions safety component. The current component had traditionally been machined using a metal alloy material, which was thought to be the cause of the excess wear on surrounding components. Additionally, this component was expensive to manufacture, since the material was costly and the machining process is time consuming and required significant post-process finishing. GOAL The engineering & design teams at ATK focused on reducing manufacturing costs associated with machining the components, reducing direct materials costs associated with the high performance metal alloy, reducing time to market for a revised product and producing a surface finish that would interact more favorably with the other moving components in the assembly. continued …
