<p>A method and apparatus for monitoring tool conditions during a machining operation utilizes a bolt transducer assembly (30) to monitor changes in tensile load on a bolt (26) securing two machine components (12, 24) together. During the machining operation, the cutting force loads of the interface of two machine components (12, 24) will vary as the cutting forces vary. A transducer assembly (30) is mounted in force transmitting relation between the threaded connector (26) and other machine components (12, 24). When the cutting force loads on the machine component increases, there will be a corresponding decrease in the tensile load on the bolt (26), and vice versa. The change in tensile load on the bolt (26) is continuously monitored to provide an indirect indication of the cutting forces on the machine tool (10). The output signal from the transducer (30) is used to extract information concerning the condition of the cutting tool (18).</p> |
