That is, the drive control unit 53 of the machine tool drive unit compares the unique identification data given to the split signal with a comparison value and transmits a confirmation signal to the remote wireless operation unit 30 when the comparison is performed. When the signal is received by the remote wireless operation unit 30, the next sequential operation signal is transmitted in the form of a divided signal, thereby enabling stable and accurate control of the machine tool. At this time, if the acknowledgment signal has not been received, the same divided signal which has already been transmitted is retransmitted to the machine tool driver.

As such, the machine tool wireless control according to the present invention according to the unique identification data and the confirmation signal between the devices by transmitting and receiving confirmation signals in both directions as compared with the conventional technology of receiving and transmitting one-way data from the control device to the machine tool. By controlling the machine tool more stably, the device can fundamentally block the malfunction of the device due to communication failure or crosstalk, and can prevent the occurrence of product defects.

On the other hand, when the input signal is input by the remote wireless operation unit 30 determines whether there is a signal to be transmitted (s170), if there is a signal is divided by the predetermined time unit and the divided signal drive transmission and reception of the machine tool drive unit Send to negative.

Subsequently, the process is repeated by comparing and determining the unique identification data applied to the split signal in the machine tool driver and transmitting a confirmation signal to the remote wireless operation unit.

(S180).

For example, if the predetermined time is set to 5 minutes, the power is connected to the axial switch of the machine tool wireless control device, and then an operation signal is input by using the axis selection switch, the magnification selection switch and the manual pulse generator. When controlling a machine tool, if there is no input of an operation signal such as the switch for a preset 5 minutes, the radio controller automatically enters an operation standby state.

In addition, the predetermined time may be set differently according to the situation and convenience of the operator.

On the other hand, in the case where the machine tool driver 50 compares the unique identification data given to the split signal with a comparison value, the acknowledgment signal is transmitted to the remote wireless operation unit 30 and the received signal is received. The divided signal is restored to a pulsed input signal (s250), and separated by each function, and then buffered by the driving buffer unit 55.

The restored input signal is output as a control signal of the machine tool connected by wire through the driving control unit, and the control of the machine tool is performed accordingly (s260).

In conclusion, the machine tool radio controller of the present invention not only improves the convenience of portability and operation, but also compares the unique identification data given to the split signal by the comparison value with the comparison value in the process of the remote radio. By sending a confirmation signal to the control panel, it is possible to prevent interference due to crosstalk of signals between machine tools installed in the workplace.
