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 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 device.
Claims21
A numerical control system for controlling a machine tool, comprising:
- control means for controlling the machine tool;
- external portable storage means for storing data;
- means for disabling said control means;
- read/write means, operable when an external portable storage means is manually coupled thereto, for reading data from said external portable storage means and for writing data to the external portable storage means;
- and
- determining means for determining whether the external portable storage means is coupled to said read/write means;
- said disabling means disabling said control means when said determining means determines that the external portable storage means is not coupled to said read/write means.
A control system for controlling a machine tool, comprising:
- control means for controlling the machine tool;
- external portable storage means for storing data;
- read/write means, operable when said external portable storage means is manually coupled thereto, for reading data from said external portable storage means and for writing data to the external portable storage means;
- and
- means for generating recording data to be recorded in said external portable storage means, including operations performed by said machining tool and a work record of work performed by an operator of said machine tool.
