Weakening workpiece involves determining acting forces between tool and workpiece, comparing with predefined force value and producing information indicating whether determined force is within defined limits of defined force value

摘要

The method involves placing a tool (10) between the workpiece and a support and weakening the workpiece by relative movement of the tool and the workpiece, determining the acting forces between the tool and the workpiece (especially the axial load), comparing the determined force with a predefined force value and producing information based on the comparison that indicates whether the determined force is within defined limits of the defined force value. An independent claim is also included for a method of weakening a workpiece.
