Appeal No. 1999-0086
Application No. 08/612,820
production run speed of a sheet fabrication machine in which
historical data pertaining to machine positioning parameters
is collected and stored in a database in machine memory.
This historical data is retrieved from the database and
utilized by the system controller to calculate the maximum
allowable speed for each machine positioning move.
Claim 1 is illustrative of the invention and reads as
follows:
1. A method of producing parts from a worksheet in at least
one sheet fabrication machine comprising the steps of:
(a) determining a number of parameters which affect each
positioning move by said machine to produce each part from
said worksheet;
(b) storing in a memory means available for said machine
historical data indicative of how each of said parameters
affects the accuracy of said each part produced from said
worksheet by said machine;
(c) inputting parameter values based on said stored
historical data to a processor means of said machine to
calculate positioning parameters providing for maximum
allowable speed for said each positioning move by said machine
to produce said each part from said worksheet; and
(d) utilizing said calculated positioning parameters for
said each positioning move to optimize the minimum safe
positioning time for said each positioning move so that each
part is produced with the requisite accuracy from said
worksheet at the fastest allowable production speed.
The Examiner relies on the following prior art:
