A method for controlling a power tool includes ascertaining a workpiece characteristic of the workpiece to be processed from previously acquired measured values, determining the workpiece material from the workpiece characteristic of the workpiece to be processed, specifying initial values, which are suitable for processing the workpiece made of the determined workpiece material using the power tool, for machine parameters such as feed, speed, and torque, storing the initial values for putting the power tool into operation with machine parameters set to the initial values and/or putting the power tool into operation with machine parameters set to the initial values. A cooling constant is ascertained according to the Newtonian cooling law as the workpiece characteristic of the workpiece to be processed. To ascertain the cooling constant, the ambient temperature is measured, the workpiece is heated, and the actual temperature of the workpiece is measured, whereupon the cooling constant is computed.

A method for producing a material that has the primary desirable properties that can be used for electrical terminal connectors. The present invention is directed at a clad material having high electrical conductivity, specific strength, good ductility, compatibility with joining materials, and low cost properties, and the method for making the material. In an aspect, the cladded material is made from one or more metals that collectively, have the properties discussed above. In an aspect, the cladded material is a transition-metal interconnector for electrical terminal connectors. In an exemplary aspect, the material is cladded aluminum and copper. The present invention relates to cladding materials built for use in connecting materials with different properties (e.g., aluminum and copper) in cathodes and anodes.
