1. a numerical control device, described device has the single program block switch for arranging one way sequence block mode, described device performs a series of program blocks in job sequence with being used for sequence of operation by starting component, to control the operation of the driving mechanism of lathe, this numerical control device comprises:

  • Execution amount setting unit, described execution amount setting unit is for arranging the accumulative execution amount of the job sequence intending being performed by the single operation of described startup component simultaneously;

    AndJob sequence implementation controller, described job sequence implementation controller is used for batch processing and measures corresponding program block with the described accumulative execution arranged in described execution amount setting unit, described job sequence implementation controller;

    After the described startup component of operation, determine whether to utilize described single program block switch to establish described one way sequence block mode,If determine that described one way sequence block mode is set up, after the described startup component of operation, initialization count-up counter,Read the program block of job sequence and explain the operational order in the program block read,Generate position command based on the processing final position in the current location of instrument and described operational order, and perform the control of the operation of the driving mechanism of described control lathe, to impel lathe to process workpiece according to the data in single program block,The execution amount of performed program block is amounted in described count-up counter,Repeat above-mentioned process, until the execution amount amounted in described count-up counter exceedes the accumulative execution amount arranged in described execution amount setting unit,When the execution amount amounted to exceedes the execution amount added up arranged in described execution amount setting unit, determine the block count certificate whether also having any plan to be performed in described job sequence, andAnd if if the block count also having any plan to be performed is set up according to described one way sequence block mode, then suspend further process until described startup component is operated again.
