Appeal No. 95-4325
Application 08/006,957
deviations from optimum machining values or the exceeding
absolute boundary values and these deviations and boundary values
constitute a range that meets the claimed language. Thus, it
appears that the Examiner finds that the Pilland teaching of a
data base of the deviations from optimum machining values or the
exceeding of boundary values meet the claimed tool criteria.
Upon a closer review of Pilland, we find that Pilland
teaches in column 1, lines 21-26, that for the machine tool to
operate optimally, data concerning the workpiece, the tool, the
machine itself, the cutting process to be used and general
boundary conditions such as life, wear, etc. must be taken into
consideration. In column 1, lines 50-63, Pilland teaches that
the determination of control data to operate optimally the
machine tool requires the determination of the selection of the
optimum cutting edge geometry, the correct bit type, optimum
cutting velocity, and the calculating of the feed for the tool
slide, the cutting depth, the number of cuts, worming spindle
capacity and the cutting edge contact time. In column 2, lines
5-22, Pilland teaches that their invention stores in a data base
the various machine tools and machining operations. The data
base for each machine tool contains data relative to the given
machine tool, such as rpm range, field of drive, drive
