characteristic (force, capacity, torque), drive gear steps, axle
feed forces corresponding velocities, maximum cutting force,
work-piece clamping force, speed limits, chuck conditions,
coefficients of friction, tailstock, steady rest and static and
dynamic stabilities. Pilland further teaches in column 2, lines
23-37, that additional information stored in the data base
includes data concerning the tools insertable into a given
machine tool such as individual types of tools, their stability
and dimensions, loading capability, working range, grades of the
bit and etc. In addition, Pilland teaches that additional
information stored in the data base includes data concerning
individual processing methods, such as data relating to general
boundary conditions of the machining of workpieces such as tool
wear, etc.
In column 3, lines 6-38, Pilland teaches the subroutines
which make possible the selection, determination and computation
of all these above mentioned variables for an optimal machining
process. Pilland teaches that the operator is only required to
enter data relative to the material of the work piece, the type
of tool to be used and the surface quality desired of the article
to be produced. The data processing unit determines by means of
the subroutines the suitable cutting data including the weighting
