The invention relates to a method for machining a workpiece (0, 0') into a piece good (1, 1') in multiple machining processes (Bj) using a machine tool (10) with multiple tools (12j). In each machining process (Bj), the tool force (F) exerted onto the workpiece (0, 0') is measured as a chronological sequence of measurement signals (Sj) by means of a piezo electric force sensor (14), wherein in a learning phase (V1, V2, V3, V4), a first workpiece (0) is machined, a quality feature (Q) is checked, and an accepted-part characteristic (GKij) is ascertained and is classified into an accepted-part class (GCj); and in a subsequent phase (V5, V6, V7), another workpiece (0') is machined, and a piece good characteristic (SKij) is ascertained and is classified into the accepted-part class (GCj). Thus, a first workpiece (0) is identified as an accepted part and is classified into an accepted-part class, and for a subsequently machined workpiece (0'), the workpiece characteristic (SKij) is used to ascertain whether the subsequently machined workpiece is classified into the accepted-part class (GCj) without needing to check whether the additional piece good has the quality feature (Q). The classification of the piece good characteristic (SKij) into the accepted-part class (GCj) is used to automatically arrive at two conclusions as to whether the additional piece good is an accepted part or a rejected part and whether required tools are worn or not, and if so which of the required tools are worn.

Abrégé

A method for generating a calibration function of a WIM sensor that is arranged in a roadway and measures a wheel force exerted on the surface of the roadway includes recording the roadway's road profile. A wheel force is determined by a simulation. The simulation is used to determine the dependency of the wheel force on the road profile for at least one position of the road profile that has been recorded in the first step. The dependency is used to minimize the influence of the road profile on the measured wheel force of the WIM sensor.

A measurement transducer for simultaneously measuring a force that can be both dynamic and static includes at least one piezoelectric transducer element having element surfaces on which the force generates electrical polarization charges proportional to a magnitude of the force. The measurement transducer includes a resonator element which can be excited to at least one resonance frequency and undergoes a transverse expansion from the action of the force in a transverse direction to the force. The magnitude of the transverse expansion is proportional to the magnitude of the force and causes in the resonance frequency a change that is a function of the force.
