摘要:
A numerical control system executes part programs which contain parameters and arithmetic expressions containing parameters. A parameter table containing parameter values is employed to evaluate parameters and arithmetic expressions during the execution of a part program, and means is provided which enables parameter values to be changed by part program instructions or manual data entry. Macroprograms, such as canned cycles, are stored in the numerical control system in a generalized form in which their instructions contain parameters and arithmetic expressions in lieu of constants. Prior to calling such a macroprogram, the part program assigns suitable values to the parameters employed in the macroprogram.

A numerical control system comprises a high speed operation buffer 27 for storing all the NC control data (interpolation movement amount or acceleration or deceleration data, etc.) occurring in time series by executing apart program, a time series data parallel display part 62 for reading and displaying the data in time series, an optimization processing part 61 for making the edit process such as recalculation process to deletion of Null data, etc. and temporally shift the group of specific data or change the pattern in the group of said data, and a second high speed operation buffer 60 for storing the processing result. The series of processes are performed by a personal computer (PC) 51 connected to an NC apparatus 1 to be able to exchange data. The data stored in the second high speed operation buffer 60 is transferred to the side of the NC apparatus 1, and read and executed, whereby the optimal processing with temporal editing is performed at high speed.
摘要:
A numerical control unit (NCU) uses character codes to communicate with an external input/output apparatus. Further, internal NCU data is stored in an array format corresponding to a display format. Further, while one set of data is being executed by the NCU, another set may be corrected by the user. Further, program data may be specified as variables rather than actual numerical values. Still further, memo data is provided to describe each piece of data. Finally, input program data is directly sent to a buffer where it is used to control a machining operation.

摘要:
By implementing a sequence control in a numerical control, tool-related machining operations and position elements are executed depending on the technology-dependent sequence in the machining program so that all cycles of a machining operation are selected consecutively as modal cycles, with all cycles being selected consecutively for a position element for each cycle for a machining operation, and the respective operation being executed at the position of the respective position element prior to the following cycle being selected as a modal cycle for an operation. Thus unnecessary tool changes are avoided and therefore machining productivity is increased.
摘要:
High-speed data processing units are interposed on one-to-one basis between a host computer and each of NC units corresponding to each of NC machine tools. Each of the high-speed data processing units converts data transmitted from the host computer to each of the NC machine tools into NC data, and then inputs the data to each of the NC units, thereby making unnecessary for the NC units and the host computer to convert the data into NC data. Further, each of the high-speed data processing units temporarily stores machining data or the like transmitted from the host computer, thereby enabling each of machine tool bodies to continue its machining operation without being disturbed by the timing of data transmission.
