Training method of numerical control device and processing program with educational function

摘要

The present invention provides an NC system (apparatus and method) for updating a machining program having more than one teaching mode. The present invention enables a machine operator to selectively replace blocks of the preexisting machining program with machine code data produced in one of the teaching modes during use of the machine. The teaching modes are changeable between an automatic teaching mode, a manual mode and an a manual data input (MDI) teaching mode. After the operation of the machine in one of the teaching modes is complete, the machining program is updated and stored. Thus, the machining program can be updated with minimal effort by the operator.
