A metal forming machine for cold forming a metal product to a desired dimension and/or configuration includes a forming means with at least one movable part for applying load to the metal product. A position sensing means establishes a measured position of the movable part indicative of a measured dimension and/or configuration of the metal product, and a load measuring means establishes a measured load applied by the moving part. A control means selects a nominal load (nom load) setting to achieve the desired dimension and/or configuration (pos nom), and enables actuation of the forming means until a calibration load (cal load) is reached where the position sensing means establishes the measured dimension and/or configuration (pos cal), whereupon the load is lowered. The control means then establishes a new load setting as a function of (pos nom) minus (pos cal), and reactivates the forming means to the new load setting to form the metal product.
