Abstract:

The report presents the latest available machining data on materials used in airframe manufacture. The information presented herein is a compilation of data on cutting speeds, feeds, tool materials and tool geometry for typical machining operations on most types or classes of work materials. Section I includes a machinability index showing the ease or difficulty, expressed in percent, to be expected in machining various materials when compared with B-1112 steel having a machinability rating of 100. Section II relates suggested cutting speeds, feed rates, tool material, tool geometry and pertinent remarks for machining various work materials. The information contained herein is not intended to represent minimum or maximum limits for each situation. It is, however, felt to be adequate for initial set-ups providing good sound basic machining practices are employed.
