摘要： The present invention relates to a resolver excitation signal generating apparatus for supplying a reference excitation signal to a resolver attached to a motor for driving a robot or a computer numerical control machine. When a sine-wave signal is transferred from a signal generator to the resolver, the signal is filtered by a low pass filter, amplified up to the rated voltage by means of a line driver and supplied to the resolver, thereby allowing the position of the motor to be controlled exactly.

摘要： Disclosed is a position controller for a tilting head in a machining center. The position controller includes an offset attachment having a body combined to the tilting head and a spherical contact secured to the body, an offset detector built in the machining center such that the offset detector move out into a process area of the machining center and automatically detects a tool offset from a contact point with the spherical contact, a storing unit individually storing first and second tool offsets by respective rotation positions of the tilting head, and an operator generating a transform offset of the first tool offset by a rotational transform and a center error vector from the transform offset and the second tool offset. Accordingly, the center error of the tilting head is automatically detected and corrected in the machining center.

摘要： A circuit is provided for detecting peaks of a sinusoidal input signal includes circuitry for generating first and second sinusoidal output signals that are out of phase with one another and with the sinusoidal input signal. A comparator block compares the sinusoidal output signals to determine instances where the amplitudes of the first and second sinusoidal output signals cross over each other. The sinusoidal output signals may lead the sinusoidal input signal somewhat so that, after taking into account processing delay, the indicated crossover instances substantially coincide with peaks in the sinusoidal input signal such that a trigger signal generated by the circuit accurately indicates the timing of the peaks.

摘要： An automated manufacturing system includes two simultaneous and independently operating toolheads accessing any location within the same work volume, with the exception of locations in proximity to each other. The system includes a bed platform connected with X and Y linear axes. A θ rotational axis rotates the bed and its linear axes as a unit. A first toolhead has a fixed position relative to the θ axis, and a second toolhead is coupled with a linear R axis parallel to the bed. The bed X and Y axes move the bed relative to the first toolhead, enabling the first toolhead to reach any portion of the bed. The R linear axis and θ rotational axis allow the second toolhead to move almost anywhere in a circular area that is always centered near the first toolhead. The system's kinematics ensure that it is impossible for the toolheads to collide.
