摘要： This invention relates to a machine tool having two main spindles which are subject to driving control by servomotors (1 and 2) by giving velocity commands (Vcmd1) and (Vcmd2) for controlling, respectively, the speed of rotation of a first main spindle and that of a second main spindle to speed control circuits (3 and 4), thereby controlling the two main spindles of a machine tool such as a lathe in synchronous operation in order to machine a work efficiently. In the present invention, the angles of rotation of the main spindles are brought into conformity to effect the synchronous operation without fail and to enable a catch of another work during rotation.

摘要： In the conventional industrial robots, a maximum instructable speed is fixed irrespective of the kind of operation and the time constant during the acceleration or deceleration is fixed too, so that the load exerted on the motor that drives the robot arm will not exceed a maximum output. In the robot controller of the invention, a maximum speed and a time constant depending upon the content of operation of the robot are designated to the robot control axes (3) from a control unit (1) that includes a select table memory (4) for each kind of the operation that will be instructed to the robot. The robot therefore operates at high speeds without exerting increased burden on the operator.

摘要： An output system for determining an axial speed for a CNC apparatus which controls the speed depending upon a residual error between the position instruction and the detected position data in order to control positions of the axes. This system comprises means for determining the present speeds of axes from the residual errors, means for determining the present actual speed by combining the present speeds of the axes, and means for producing an output that represents a ratio of the present actual speed to a predetermined maximum speed. An error register stores a residual error (residual quantity) between the position data detected by the position detector and position instructions for the axes from the MPU in the CNC apparatus. A speed instruction is generated from the error register to control the speed. In this case, there exists a predetermined relationship between the residual error and the present speeds of the axes, and this is utilized to derive the present speeds of the axes from the residual errors. When the present speeds of the axes is obtained, the actual speed of the work table can be determined by combining the speeds of the axes. The actual speed thus obtained is converted into an output that represents its ratio to the system's maximum speed which has been set according to a parameter.

摘要： A method and an apparatus for numerical control to automatically and repetitively carry out numerical control in compliance with a numerical control program modified by utilizing an override function. Whether a teaching instruction is input or not is discriminated (S1) while a numerical control program is being executed. When it is determined (S2, S6) that the feed speed or the main axis speed override memory instruction is input in the teaching mode, an override value set manually using an override switch is written (S10) onto the end of a block under execution of the numerical control program. When the numerical control program is executed on the next time and thereafter, the override operation is automatically carried out as set manually.

An interface device between the numerically controlled apparatus (NC) and the electric power control circuit (PC) is equipped with a memory (50) for real speed onto which the real speed data will be written from the numerically controlled apparatus (NC) and which can read the written data from the electric power control circuit (PC), and is further equipped with a memory (51) for corrected speed onto which the data of corrected speed will be written from the electric power control circuit (PC) and which can read the written data from the numerically controlled apparatus (NC). On the side of the electric power control circuit (PC), therefore, the data is read from the memory (50) for real speed to determine the real speed of the numerically controlled apparatus (NC), and is further written onto the memory (51) for corrected speed to control the real speed of the numerically controlled apparatus (NC).
