8.Al APPENDIX VIII.A CHARACTERISTIC RELATIONS OF MACHINE TOOLS VIII.A.l: GENERAL REMARKS Several interesting relations emerged during the study of light machine tools and heavier rolling mills for use in the manufacturing process. Within certain bounds, machine tools have several characteristic properties or parameters relating their volume, mass, and power consumption, independent of the size or type of machine. Among these parameters are the following: Mean density= mass/volume Specific power consumption power consumption/mass VIII.A.2: LIGHT MACHINE TOOLS Data was collected on a variety of types and sizes of lathes, milling machines, band saws, and drill presses made by various American firms. The machines, all of the types found in industrial machines shops, include: "Do All" saws "Claremont" heavy duty drills "Monarch" lathes of 16" to 25" swing "Milwaukee" milling machines "Brown and Sharp" milling machines "Lodge and Shipley" lathes "South Bend" lathes and milling machines The volume, mass, and power consumption of these tools was taken from the manufacturer's literature in the following way: Volume - was based on the extreme dimensions when the machine is set up including extensions, knobs, crank handles and controls. When the set-up dimensions were not available, the shipping volume was used. Mass - from the weight setup as listed. If not available, the shipping weight was used.
