摘要： A numerical control device wherein a sinusoidal signal generated by a sine wave generation part is input by a control loop excitation part to a control loop of the control object, the input signal input to the control loop and the output signal from the control object are sampled by the data acquisition part periodically, and the sampling data is used by the frequency characteristic calculation part to calculate the frequency characteristic of the control loop to control the control object, wherein the frequency characteristic calculation part uses data obtained by inputting a sinusoidal signal obtained by shifting an initial phase of the sinusoidal signal by a phase shift part provided at a sine wave generation part by exactly a certain amount to the control loop a plurality of times to calculate the frequency characteristic of the control loop to thereby improve the measurement precision regardless of the sampling frequency.

摘要： A method and apparatus are provided for providing for controlled oscillation of a tool centerpoint associated with a function element carried by manipulator simultaneously with motion of a workpiece feature relative to a predetermined location. The tool centerpoint describes a predetermined pattern relative to the workpiece feature as a result of the combined motion. Tool centerpoint oscillation occurs in an oscillation path between two extremes determined by pattern parameters defining pattern amplitude measured with respect to a pattern longitudinal axis. The direction of the oscillation path is defined by input signals representing angles measured relative to a rectangular coordinate system used for defining the predetermined location. The rate of tool centerpoint motion is defined by an input signal representing velocity.

摘要： Suspending an armature on a parallelopiped basket of flexure springs, with a lateral effect cell position sensor and an X-Y source of motive power, provides a precision X-Y positioner with minimum static friction and with feedback of actual position for closed loop servo operation under computer control. The armature is arranged for X-Y motion within its own plane, and is arranged to carry a gripper, cutting tool, or other end effector. The parallelopiped basket includes a stator, a first set of flexure springs, a flexure spring carrier mounted on the first set of flexure springs, a second set of flexure springs mounted on the flexure spring carrier, and the armature mounted on the second set of flexure springs in turn mounted on the carrier. The basket suspends the armature with freedom of motion in the X and Y dimensions without static friction associated with sliding or rolling motions. Motive power to reposition the armature to the desired X-Y coordinates is provided by a positioning motor made up of a pair of U-shaped permanent magnets each having coil-wrapped U-shaped pole pieces mounted orthogonally to each other. Once the armature is positioned, flux differentials applied to teeth on the armature oppose any forces tending to move the armature from the desired X-Y coordinates.Armature position sensing is by LED on the armature and a lateral effect cell, mounted on the stator, which feeds back sensing signals to a computer to form a servo loop. The computer can vary the compliance of the flexure springs by adjusting the motor control signals as a function of a compliance variable.

摘要： An improved final servo control for numerical control systems of the type which perform linear and/or circular interpolation by iterative updating of commanded position signals. The improvements are embodied in means to sense when the servo loop has had an offset error introduced by drift or aging of the final amplifier or similar components, together with means for progressively and automatically removing such error; and by means to avoid attempts at extreme acceleration or deceleration beyond the ability of the servo power element (motor) to accomplish, --by creating from an iteratively updated primary position command signal, whose rate of change may suddenly alter by a wide margin, a secondary position command signal which varies ultimately by the same amount but at a lesser rate of change.

摘要： A converter is disclosed for operating on the proportional control signal output of a contouring-type numerical control system to make it suitable for use with an on-off servo of the type employed with tracer-controlled machines. The converter accepts the square wave outputs of the command counter of the numerical control system, the output of the feedback resolver rotor (the stator being energized by the output of the reference counter) and a voltage proportional to the rate of motion of the controlled machine member. When the first zero crossing occurs of the command or feedback wave a time delay is initiated which is proportional to the speed of the output member by adding the voltage proportional to the member speed to a ramp voltage initiated at the crossover of the appropriate wave, and detecting the zero crossing point of the sum. If the crossover point of the second input square wave occurs during the delay period no control signal is provided to the output servo. Therefore, a dead zone proportioned in width to the speed of the output member is created. If the square wave signal crossing occurs after the time delay an output signal to the servo is provided of a sign dependent upon which of the input square waves crossed zero first.
