摘要：
A system for preparing an NC sentence for two-step drilling according to which a hole formed by the first-step drill is further deepened by the second-step drill of a smaller diameter. Data related to a machining shape are input (S1), and data related to machining conditions are input (S2,S3) inclusive of a first clearance and a second clearance. An NC sentence is prepared (S4) for the first-step drilling and the second-step drilling from the bottom of the hole formed in the first-step drilling to the final point of machining. This helps reduce the time for the second-step drilling.
