ABSTRACT:
In an NC-lathe comprising a thread touch sensor provided with a touch portion to be brought into contact with an effective radius/diameter portion of a screw thread, an automatic measuring device electrically connected to the thread touch sensor, and an automatic correction device connected to the automatic measuring device; an effective radius or diameter of a screw thread is measured by bringing the touch portion of the thread touch sensor into contact with an effective radius/diameter portion of the screw thread, the measured dimension is compared with a desired dimension, and when a difference is produced between the respective dimensions, the NC-lathe is controlled by correcting an amount of machining by means of the automatic correction device.
