Patent ID: 7016758

Claim:
A machining program transmission method for a system comprising one or more NC machine tools having a machining operation mechanism section for machining a workpiece into a desired shape and a control device for controlling said machining operation mechanism section on the basis of a machining program, a transmission device for transmitting said machining program, and a terminal device for requesting the transmission of said machining program, said NC machine tools, said transmission device and said terminal device being connected mutually via an electrical communication line, and said machining program being transmitted from said transmission device to each NC machine tool via said electrical communication line according to the request from said terminal device, comprising: a step of attaching an identification information of the machining program used for machining to a medium on which information regarding the machining to be carried out by said NC machine tool is recorded, a step of reading a program identification information attached to said medium using said terminal device, inputting the identification information of said NC machine tool for carrying out the machining recorded on said medium into said terminal device, and transmitting said program identification information and said machine identification information from said terminal device to said transmission device via said electrical communication line, a step of transmitting the machining program corresponding to said program identification information from said transmission device to said NC machine tool corresponding to said machine identification information via said electrical communication line on the basis of said program identification information and said machine identification information transmitted from said terminal device, and a step of storing the machining program transmitted from said transmission device in the control device of said NC machine tool.
