Abstract
An access-level control apparatus includes an NC machine tool, an RFID that is held by an operator and stores an ID given to the operator, a reader unit that reads out the ID, an authenticating unit that determines operator processing limitation information including an operable range by the operator associated with the ID or display information provided to the operator, an operation/display limiting unit that limits processing by the operator for the NC machine tool on the basis of the operator processing limitation information, and a separation detecting unit that periodically reads out, after the authentication, the ID in the RFID, performs re-authentication, and detects presence or absence of separation of the operator. When detecting as a result of the re-authentication that the operator separates from the NC machine tool, the separation detecting unit releases the authentication.
