BIDIRECTIONAL INTERFACE DEVICE FOR NUMERICAL DONTROL DATA

摘要

PURPOSE:To send the recompiled NC (numerical control) data back to a host computer by providing a bidirection interface device on a communication circuit which connects the host computer and a CNC device. CONSTITUTION:The recompiled NC data is transmitted to a host computer 1 from a computer numerical computer CNC2 through an interface 2c and a data circuit 103 in the form of the compiled NC data by an indication given from a console 2b. In this case, an output indication is sent to an interface 36 of a bidirection interface device 3 from the interface 2c. A transmitting request is delivered and the NC data is sent from the circuit 103 opened by a built-in CPU 31 through the same route via an RAM of a memory 33. Then the NC data is sent to a data circuit 101 via interfaces 36 and 35 and then sent back to the computer 1.
