Abstract:
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 parts from said worksheet; (b) storing in a memory means of said machine historical data indicative of how each of said parameters affects the accuracy of parts 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 maximum allowable speed for said each positioning move by said machine to produce parts from said worksheet; (d) utilizing said calculated maximum allowable speed for said each positioning move to optimize the minimum safe positioning time for said each positioning move so that parts having the requisite accuracy are produced from said worksheet at the fastest allowable production speed; (e) running at least one static process control (SPC) test to produce data from different loads in different conditions for different sheet fabrication machines; and (f) using said date from said SPC test to eliminate the differences between said different sheet fabrication machines due to tolerances in the manufacturing of said different sheet fabrication machines to optimize individual positioning moves of each of said different sheet fabrication machines.
