M777 Lightweight Howitzer
Dynamic Flowform has successfully flowformed cradle and recoil tubes for the M777 light-weight 155mm Howitzer guns. This work was performed for the United States Army through the National Center for Excellence in Metalworking Technology (NCEMT). These gun systems are made from titanium 6-Al-4V (grade 5). They will be used by the both the Marine Corps and Army. Initially, the cradle and recoil tubes were produced by extruding a thick-walled tube, measuring each individual extrusion for roundness and straightness, bump-straightening the extrusion, and then machining the extrusion wall thickness to meet the final tube requirements. By flowforming, Dynamic has been able to offer the Army a net-shape cradle and recoil tube which eliminates several manufacturing processes and reduces material waste. The flowforming manufacturing approach Dynamic developed offers the Army substantial cost-savings.
