Machining Data Concepts or Evaluating New Cutting Tool Materials 650110
Cost data are presented which provide justification for making systematic studies of all types of machining processes in order to select the most applicable tool materials. Full tool life tests are suggested for obtaining reliable machining data. Specific tool life test data are supplied for the drilling, reaming, and tapping of 4340 steel at 42 Rc, for the face milling of 32510 and 60003 grades of malleable iron, and for the comparative evaluation of T-15, and ultrahard high speed steels, C-8, titanium carbide base, and ceramic cutting tools. Sources of machining information are referenced along with a description of the Air Force Machinability Data Center.
