Improved Buttress Thread Machining for the Excalibur and Extended Range Guided Munitions

Abstract

Raytheon requested the NCDMM to evaluate and optimize buttress thread machining. Raytheon's suppliers have had problems producing buttress threads that meet the specified tolerances. These suppliers have tried various types of manufacturing methods but are still unable to consistently produce quality buttress thread components for Raytheon. NCDMM was asked to do the following things: optimize machining of fine pitch Class III Buttress Threads for the Excalibur and ERGM components. Provide training to Raytheon personnel to adapt the newly optimized buttress thread machining technique to all Excalibur and ERGM components. Assist Raytheon in evaluating and optimizing the buttress thread measuring techniques and instruments/gages.
