摘要： This invention relates to an end shape data input system in an ineractive numeric controller. A question for defining the center point (P2) of a product is set with reference to the center point (P1) of the end face of a work, and the coordinate data are inputted to define the center point (P2). The shape data are inputted with reference to the defined center point (P2). An interactive numeric controller converts the inputted shape data to the coordinates with reference to the defined center point (P2) and prepares a final machining program.

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.
