摘要： A system in which a machine tool is controlled by a digital computer and an operator to perform a sequence of machining operations. In a programming mode, the machine tool cutting element is positioned by an operator relative to an object to be machined. The relative position of the cutting element is adjusted so that the cutting element passes through a sequence of spatial points at which a subsequent machining operation is desired. In association with each point, a sequence of digital signals is generated in a programming mode in response to an operator directive and that sequence is stored in a digital computer memory. Subsequently, in a machining mode, stored sequence is translated to a machine tool control signal which drives the machine tool. An operator may direct the digital computer in an editing mode to select ones or groups of the stored sequences and to modify those selected sequences. The operator may also direct the computer in the machining mode to generate the corresponding control signals for selected ones or groups of the stored sequences so that the corresponding machining operations are performed.

摘要： Machine path pulses produced by X, Y and Z slide movements of a numerically controlled machine are compared with pulses derived from the programmed data independently of those which produced the slide movements on command, extra temporary storage being employed to delay the production of the tracer path pulses to compensate for the machine position lag behind the electronic position produced by the command generator. Gated X, Y and Z updown counters, each counting up on its machine path pulses and down on its tracer path pulses, tend to establish a null condition within up and down count limits to either side of an initially set value. A gating network generates an off null signal when any of the counters exceeds the null limits. Clock signals modulated by the off null signal change the rate of generation of the tracer path pulses to thereby restore the counters to the null condition. When the off null signal persists longer than a predetermined interval, an error signal is produced to stop the machine operation.

摘要： A control for a robotic actuator employs a position processor to determine the phase of a pair of electrooptically generated position signals as well as to keep track of the number of whole cycles of the position signals. Whole cycles are tracked using a prediction technique depending upon the continuity of position and velocity. A command processor employing the sensed position produces a velocity signal for driving the robotic actuator. When very slow motion is sensed, the response of the controller is appropriately reduced to maintain a velocity command signal generally in proportion to the motion.

摘要： A mechanical element positioning control system. Position measuring means supply actual position and a computer supplies desired position as the least significant 11 bits of an 18 bit signal to corresponding digital to analog units, each comprising an 11 bit register and an 11 bit digital to analog converter. A differential amplifier compares the outputs of the digital to analog converters and generates a position error signal. A threshold circuit operates to complement the most significant bit of the D/A registers when exceeding of a maximum allowable analog error occurs. A servo system responsive to the position error signal positions the mechanical element to eliminate difference between desired and actual position. By eliminating the seven most significant bits representing desired and actual position, the total range is divided into 2.sup.7 separate fields so that D/A units of practical accuracy may be employed to make feasible a positioning control system of required accuracy and range.

摘要： A servo system, particularly well suited for use in a computerized numerical control system for a large machine tool, in which a plurality of axis controlling servo circuits are controlled by one computerized axis controller. As each controlled axis moves, an attached resolver's output is digitized to generate a digital position feedback signal which is compared to the desired position in the computer. The resultant error signal is converted to an analog voltage to control said axis motion. A digital clock and counter drives two digital to analog converters to create the two resolver inputs, and supplies timing signals to the computer, thus synchronizing the system.
