| 20090219015 | APPARATUS FOR MEASURING KINETIC PARAMETERS OF PUNCH - An exemplary apparatus and method for measuring kinetic parameters of a machining tool within a press molding machine includes two magnets and two electrical conductors attached to a machining tool. The two magnets are fixed for producing two magnetic fields that are at an angle to each other. The two electrical conductors are connected to a controller to form two closed loops respectively. Each electrical conductor is located in a corresponding magnetic field and is unparallel to the direction of the corresponding magnetic field. Upon the condition that the machining tool deviates from its axial path, voltages are induced across the two electrical conductors. The controller receives the induced voltages, and determines a velocity of the machining tool's deviation from the axial path. | 09-03-2009 |
