Abstract
A numerical control system for controlling a machine tool including a control device for controlling the machine tool; external portable storage device for storing data; a disabling device for disabling the control device; a read/write device, operable when the external portable storage device is manually coupled thereto, for reading data from the external portable storage device and for writing data to the external portable storage device; and a determining device for determining whether the external portable storage device is coupled to the read/write device. The disabling device disables the control device when the determining device determines that the external portable storage devices not coupled to the read/write
Claims1
A numerical control system for controlling a machine tool, comprising:
- means for regulating commands corresponding to various operations which can be made through an operation panel of said numerical control system by an operator;
- an internal memory for storing said commands;
- means for reading said commands from said memory;
- means for analizing said commands read from said memory:
- and
- means for, while said numerical control system is driven on the basis of the contents of said commands read from said internal memory, interrupting the driving of said numerical control system, and initiating the usual operation made through said operation panel, restarting from the interrupted portion the operation made on the basis of said commands
- Whereby said numerical control system can be controlled so as to be entirely equivalent to a case where the operator controls the system through the operating panel.
