ABSTRACT:
A spark plug grinding machine is equipped with force sensors to measure grinding forces and other forces attendant to a grinding operation. Ceramic spark plug insulators are carried by spindles on a Ferris wheel into a grinding station. A control wheel engages and spins each part as a grinding wheel grinds the surface of the insulator. A three axis transducer on one of the spindles measures force components along the axis of the spindle, parallel to a tangent of the grinding wheel and in a radial direction. A torque sensor on the control wheel measures the torque as the wheel rotates each insulator. Either or both of the sensors may be used. They are coupled through slip rings to a recorder.
