METHOD FOR QUANTITATIVELY DETERMINING THE SIZE OF A SOFT ZONE AREA OF A PARTIALLY HARDENED WORKPIECE

The bolt (1) used to hold a planet wheel in an epicyclic gear train has a hardened center section (2) and soft ends (3). The workpiece hardness measurement system uses a multi-frequency eddy current measuring coil (4) which is passed along length of the bolt. Differences in the eddy currents enable...
