摘要： A system for controlling motion of machine tools and industrial robots. From the specification of a part to be cut or a path to be followed by a machine tool or robot, the system calculates for each axis, for each incremental step along the path, a position command (69), a time delay between successive position commands, and, optionally, a force command (68) based on a prediction of predicted resistive forces. Calculations are specified for precisely controlling velocity, acceleration, and jerk. The generated data is stored in a memory device and subsequently directed to the machine tool or robot.

摘要： A servo control circuit suppresses an incompletely integrated term contained in the integrated gain in a speed feedback loop of a speed control block (5) at a moment when a deviation between a position signal from a machine system and a movement instruction has exceeded a predetermined reference value. This makes it possible to control the torque instruction to the current control block (6) such that a torque is minimized that develops overshooting according to static frictional characteristics of the machine system. The operation equivalent to the one realized in the analog servo system by non-linearly operating the coefficients of a CR time-constant circuit during electric charge and discharge is realized in the digital servo control system aided by a computer.

摘要： A numerically controlled machine tool for machining a non-circular workpiece according to profile data. The servomotor drive unit of the machine tool includes a frequency voltage converter which outputs a velocity compensation signal proportional to the frequency of position command pulses in the servomotor drive units. A position error signal is modulated by the velocity compensation signal. The numerical controller of the machine tool can measure the position error and phase error, and can compensate for these errors. The numerical controller operates according to ideal profile data and measures the actual position change of a tool slide corresponding to the angle position change of a main spindle. Then, the numerical controller calculates the position error and phase error depending on the actual position change and ideal profile data, and produces execution profile data which are compensated for position error. During machining operation, the numerical controller offsets the read out position of the execution profile data by the calculated phase error so as to eliminate the phase error.

摘要： In a numerical control feed device, an objective velocity signal is produced from the difference between command pulses from a numerical controller, which indicative of an objective feed amount and an objective feed rate for a slide of a machine tool, and a feedback feed amount from a pulse generator driven by a servomotor. A subtraction circuit calculates a difference signal based on the objective velocity signal and a feedback velocity signal from a tachogenerator also driven by the servomotor and applies the difference signal to a drive amplifier for driving the servomotor. A frequency-voltage converter generates a feedforward velocity signal depending on the frequency of the command pulses. A gain adjustable amplifier amplifies the feedforward velocity signal at the amplifying ratio designated by the numerical controller and outputs the amplified feedforward velocity signal to the subtraction circuit for addition. The numerical controller determines the amplifying ratio based on various parameters such as the mechanical characteristic of the machine tool, the shape of a workpiece to be machined, an objective feed rate used in an instantaneous machining operation, and so forth.
