Abstract
Disclosed is a numerical controller that has a cutting in/out motion inserting function and configured to control a machine tool that performs lathe-turning machining in which a cutting tool moves in contact with a rotating workpiece. The numerical controller includes a cutting in/out motion inserting unit that generates a program to perform cutting in/out motion, based on operation conditions analyzed by a cutting in/out motion operation conditions analysis unit and inserts the generated program of performing the cutting in/out motion to a program to perform the lathe-turning machining.

1-6 (canceled)
A numerical controller configured to control a machine tool according to a machining program, the machine tool performing lathe-turning machining in which a cutting tool moves in contact with a rotating workpiece to form the workpiece into a desired shape, the numerical controller comprising:
- a circular motion operation conditions analysis unit configured to analyze operation conditions for circular motion instructed in the machining program;
- and
- a circular motion inserting unit configured to insert and remove the circular motion that is generated based on the operation conditions analyzed by the circular motion operation conditions analysis unit into the lathe-turning machining,
- a circular motion execution flag exec_f represents whether the circular motion is being executed, and
- the inserting of the circular motion of the cutting tool during machining makes it possible to circulate a coolant between the cutting tool and the workpiece.
