Abstract

PURPOSE:To prevent the wrong transfer of data and to improve the system efficiency by performing the comparison between the code of an applicable machine stored in an IC card and the code of a connection machineset at an NC device and transferring the data only in an applicable state. CONSTITUTION:The graphic data stored in an IC card 40 is transferred to an automatic programming device 30 and converted into an N program. Meanwhile the data on an NC program is directly sent to a memory 16. At the same time, the code of a connection machine is set by a machine code setting device 44 of an NC device 41. Thus a code comparator 45 can discriminated whether a relevant machine is applicable or not. Then the data are transferred only in an applicable state, and no data is transferred in an inapplicable state. This information is displayed on a CRT. Thus it is possible to evade such a mistake where the wrong data is sent to the device 41 to cause an alarm or a malfunction. Then the system efficiency is improved.
