  • Publication number: 20120283879
    Abstract: A next command reference value close to a “the value L serving as a reference” is read from its own path table, and if there is the read command reference value in its own path table, then it is determined whether or not the “the value L serving as a reference” reaches the command reference value. When the “the value L serving as a reference” reaches the command reference value, if there is a waiting command of waiting for other path table, counting of the “the value L serving as a reference” is stopped. When waiting for the other path table is completed, the stop of counting of the “the value L serving as a reference” is released, the command is executed, and processing is continued.

  • Patent number: 8195911
    Abstract: A memory other than a non-volatile memory in a numerical controller is divided into a plurality of memory areas in response to a command from a computer connected to the numerical controller. Whether a machining program has been stored in each of the divided memory areas is decided before a machining program stored on a hard disk in the computer is transferred to the memory other than the non-volatile memory. The machining program stored on the hard disk is then written to an area for which it is determined that no machining program is stored.
