BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
Referring to FIG. 1, an NC program editing system 11 according to the present embodiment typically includes a CPU (Central Processing Element), a memory, a hard disk, a LAN (Local Area Network) board, a keyboard, a mouse, a monitor device and the like. The NC program editing system 11 can be formed from a personal computer having a wear element. The network means 37 may typically be a network conforming to the IEEE 802.3 standard.
[0011]
The NC program editing system 11 includes an NC program editing unit 13 and an NC program sending / receiving unit 17 formed of application software forming the core of the system. The NC program editing system 11 further includes a storage means 15 which can be formed from a memory or a hard disk of the personal computer, a communication adapter 19 which can be formed from the LAN board, and an input which can be formed from the keyboard or mouse. Means 21 and display means 23 comprising the monitor device.
[0012]
The NC unit 25 and the server 31 are connected to the network unit 37. The server 31 includes hardware elements such as a CPU, a memory, a hard disk, a LAN board, a keyboard, a mouse, and a monitor device, and is a computer or other server that constitutes a CAM (Computer Aided Manufacturing) device that provides an NC program to the NC device 25. And a storage adapter 33 formed from a hard disk and storing at least an NC program. The storage unit 33 stores an NC program that has been provided to or will be provided to the NC device 25 and an NC program that has been executed in the past.
[0013]
The NC device 25 is formed by an NC device generally used in the field of an NC machine tool. A memory 27 for storing an NC program provided from the server 31 and the memory 27 are connected to a network unit 37. And at least a communication adapter 29.
