ABSTRACT Disclosed is an NC sentence creation system for creating an NC sentence for a two stage drilling operation by which a hole drilled by a first stage drilling operation is further drilled by a second stage drilling operation using a second drill having a smaller diameter, wherein machining configuration data are input (S1), machining condition data including a first amount of clearance and a second amount of clearance are input (S2, S3), and an NC sentence is created which enables the hole to be drilled in the first stage drilling operation and the second drill for the second stage drilling operation to be moved by a cut- ting feed from the bottom of the hole drilled by the first stage drilling operation to the machining end point of the second stage drilling operation (S4), whereby a machining time for the second stage drilling operation is shortened.
