To maximize the production run speed of a sheet fabrication machine such as a turret punch press, and yet at the same time maintaining the requisite accuracy for each part produced from the production run, historical data pertaining to the various parameters for effecting the positioning moves of a worksheet are measured and collected using a reference machine or a prototype machine. For each positioning move to be effected, the CNC controller of the system retrieves the historical data from a database and, using that historical data, calculates the various parameters that affect the positioning move. By using fuzzy logic, the controller becomes, in a sense, self teaching, especially if updated historical data are provided to its database store to enhance the accuracy for later positioning moves. In addition to measuring and collecting historical data from reference or prototype machines, static process control (SPC) tests may be performed for different types of worksheets under different loads. The data collected from the SPC tests are stored and can be used as the historical data. Using historical data to calculate the next positioning move, i.e., by using the past to forecast or predict the future, the maximum allowable speed is obtained for each positioning move. At the same time moves that will produce parts that have dimensions that are within the predetermined required accuracy threshold are ensured.
