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.

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.

A numerical machine tool control system includes a plurality of machine tools (11, 12, ...) controlled by a corresponding plurality of numerical control circuits (21, 22 ...), each of which includes a manual data inputting panel (31,32, ...). An automatic operation command device (8) is common to all of the numerical control circuits. Transmission means (71,72, ...) is provided between each of the numerical control circuits and the operation command device for exchanging input data for the machine tool and output data from the machine tool, for exchanging data for the manual data panel and data from the manual data panel, and for exchanging treatment program data. The entire operation of the plurality of machine tools is thereby controlled by the operation com- manddevice.

In a numerical control system an automatic programmer (11) and at least one numerical control device (21) are interconnected by a cable (CBL). A numerical control program prepared by the automatic programmer is transferred to the numerical control device. The automatic programmer includes an input unit (104) for entering data, a processor (101) which edits the data for producing a numerical control program, a memory (103) for storing the complicated numerical control program, and a display device (105) which displays a graphic in accordance with the output of the processor. The numerical control device includes a memory (203) for storing the numerical control program, which is transferred from the automatic programmer via the cable. Such a system can enable programming and numerical control processing to be carried out concurrently.
