Machine tool operation system and machine tool operation method carried out by said system

A machine tool operation system comprising:

• numerical control (NC) device connected to a machine tool body to perform numerical control;
• a computer connected to the NC device;
• and
• a tablet terminal in wirelessly communication with the computer to enable input and output of signals to and from the NC device via the computer,
• wherein the tablet terminal includes, a display unit configured to display a menu screen showing selectable various operation modes for a machine tool, on a display screen, the various operation modes being previously provided to the NC device;
• an input unit to receive inputs of a user;
• and an input processing unit to output an input signal to be transmitted to the computer based on the input received by the input unit,
• the computer includes a signal processing unit to output a command signal for a machine tool operation, the command signal being transmitted to the NC device based on the input signal from the tablet terminal;
• wherein the machine tool operation system further comprises a wireless communication unit to wirelessly send and receive signals between the tablet terminal and the computer, and
• a transmission unit to transmit signals between the computer and the NC device,
• the tablet terminal further includes software having a function to make the display unit display, on the display screen, an operation panel image on which a plurality of operation buttons are arranged corresponding to at least some executions of various machine tool operational functions previously provided to the NC device and, based on an input operation selecting the operation button of the operation panel image, to make the input unit output an input signal corresponding to the operation button,
• the computer includes
• a storage section previously storing each command code corresponding to each operation button arranged on the operation panel image, the command codes being for machine tool operations, and
• software having a function to make the signal processing unit read the command code for the corresponding machine tool operation from the storage section based on the input signal wirelessly transmitted from the tablet terminal via the wireless communication unit, and output the command code as a command signal to transmit the command signal to the NC device via the transmission unit, and
• the display unit of the tablet terminal is configured to display a menu screen showing selectable various operation modes as icons and a button for starting and displaying the operation panel image.
