PURPOSE:To obtain a numerical control working method where all workpieces can be worked, by inputting only NC data which works one workpiece into a desired shape and data which specifies a regularity of workpiece arrangement to generate NC program for scheduled working of all workpieces. CONSTITUTION:Plural workpieces Wij to be worked into the same shape are fixed to a table of a machine tool by a jig JG. m-number of workpieces Wij (m=3) are arranged at a pitch Px in the X direction and n-number of workpieces Wij (n=3) are arranged at a pitch Py in the Y direction in a grid. The workpiece W11 is a reference workpiece arranged on a reference stage S11, and NC data for working of the reference workpiece W11 on the reference stage S11 is generated and inputted. Since workpieces Wij are arranged regularly, NC data which works the reference workpiece W11 into a desired shape and data which specifies the regularity, for example, Px, Py, (m), and (n) are inputted to generate NC data which works each workpiece into the desired shape, and individual workpieces are worked with NC data to obtain parts of the same shape.
