1. A method comprising:
designing and machining a gear wheel including the following steps:
a) generating function-oriented geometry of the gear wheel using software-based, computer-assisted design,
b) generating theoretically producible geometry of said gear wheel corresponding to or approximating said function-oriented geometry using at least one software-based, computer-assisted tool,
c) generating production data representing the theoretically producible geometry,
d) machining the gear wheel using the production data with a CNC-controlled machine tool,
e) measuring said gear wheel and generating therefrom a data set of geometry of the machined gear wheel,
f) comparing the data set to the production data and determining therefrom at least one correction variable, and
g) one or more of
generating corrected production data from the production data using the at least one correction variable and machining at least one additional gear wheel using the corrected production data or
adjusting the machine tool using the at least one correction variable and finish machining said gear wheel with said adjusted machine tool,
and further comprising iteratively
h) selecting a machining tool,
i) performing step b), wherein the step of generating theoretically producible geometry of the gear wheel includes using tool data of said selected tool,
j) determining suitability of said the theoretically producible geometry, and
k) when said theoretically producible geometry is not suitable, selecting another machining tool and repeating steps (i), (j), and (k).
