    摘要： First and second tool control blocks precede and follow a corner on a tool path, respectively, and perpendicularly intersect each other at the corner. A pulse distribution computation based on NC command data in the second block is not executed at the instant that a pulse distribution computation based on NC command data in the first block ends. Rather, a pulse distribution computation based on the NC command data in the second block is performed starting at the instant that a feed speed based on the NC command data in the first block attains a prescribed speed by being decelerated. As a result, the torch of a gas cutting machine or the like will cut the corner portion quickly to a high degree of accuracy, without cutting the corner to an overly rounded shape.

    摘要： A method and apparatus for controlling the return of the movable element of a machine tool to a predetermined grid point by controlling movable element drive means in accordance with feedback pulses generated while the drive means is being driven to transport the movable element between grid points. The method includes the steps of specifying a position remoted from the predetermined grid point by a distance which is less than the spacing between grid points, computing the deviation between the specified position and the current position of the movable element, positioning the movable element at the specified position by driving the drive means on the basis of the computed deviation and feedback pulses, and driving the drive means at reduced speed to stop the movable element at the first grid point encountered following the initiation of reduced-speed drive.

    摘要： @ A system for reversing the direction of an electric discharge machine of the type in which an electrode is moved relative to a workpiece and the workpiece is machined by an electric discharge developed across the electrode and the workpiece. When the electrode contacts the workpiece to produce a short-circuit signal, a controller responds by generating a command signal the magnitude whereof is greater than a stored error between a commanded value and a number of feedback pulses produced by rotation of a motor which drives the electrode. Owing to the magnitude of the generated command signal, the stored error is converted into a value capable of reversing the direction of the electrode without delay.

    摘要： data write/read control apparatus, provided between a numerical control device and a cassette memory for writing data into the cassette memory and for reading data out of the cassette memory, as well as a method of controlling the data write/read operations. In a data write operation, a file is divided into a plurality of blocks, each comprising a predetermined number of bytes, one file constituting one input unit of data written into the cassette memory from the numerical control device. A control byte is added to the head part of each block and, when the amount of remaining storage space in the cassette memory is equivalent to one block of data, a code, indicating a shift to a subsequent cassette memory, is written in the control byte of the last block stored in the cassette memory. An external indication is given instructing when to exchange the cassette memory for the subsequent cassette. In a data read operation, the code indicating cassette exchange is sensed, whereupon an external indication is given instructing exchange of the cassette.

    摘要： An acceleration/deceleration device for a numerical controller is provided with interpolating means for periodically obtaining a minute displacement in each axis from a separately calculated minute displacement in a tangential direction. The acceleration or deceleration is carried out for a minute displacement after interpolation. Delays are successively stored in the form of interpolated minute segments and a minute displacement in a tangential direction separately calculated from a delay in the tangential direction is proportionally distributed for each minute section, thereby to obtain an output minute displacement in each axis.
