Abstract
A tapping device generates a cycle suspension squence by which a tapping process can be temporarily suspended and a cycle restart sequence by which the suspended tapping process can be restarted, thereby securing a safe operation at the time of an abnormality in the tapper or at trial cutting. Tapping wherein tapping is controlled by synchronizing the rotation of a spindle and the feed on a feed shaft. The device includes a sequence generating section which generates a tapping sequence for execution of said the tapping process, a cycle suspension sequence which slows down and suspends in synchronism the rotation of the spindle and the feed on said feed shaft to sumit detachment of the tapper from the work, and a cycle restart sequence which resumes the tapping process. A memory is provided which stores the detected oriented angle of the spindle for the start of cutting in the tapping sequence. A sequence executing section is provided which executes the tapping sequence, the cycle suspension sequence when a cycle suspension signal is inputted, and the cycle restart sequence according to the spindle oriented angle from said memory means when a cycle restart signal is inputted.
