  • Numerical control unit with set amount of execution
    Patent number: 8036770
    Abstract: A numerical control apparatus with a single block function is provided including a start button (3), an execution amount setting unit (13), and a machining program execution controller (4). Once the amount of execution of the machining program to be executed by a single operation is set in the execution amount setting unit, the machining program execution controller (4) batch executes the blocks included in the set amount of execution upon a single operation, such as a depression, of the start button (3). Additionally, upon detecting a block including a non-cutting command or a command for abruptly changing a machining direction, the machining program execution controller (4) suspends the execution of the machining program as of that block and waits for the start button (3) to be depressed again.
