Apparatus for thread testing, comprising at least one plug gauge () for testing a thread (), the plug gauge being adapted for connecting with a machine axis () of a machine tool () and a displacement sensor () connectable with the at least one plug gauge () and the machine axis () for determining a maximum path () which the plug gauge () may be screwed into thread ().

Method and apparatus for thread testing by distance measurement

The invention relates to an apparatus () for testing threads comprising a thread plug gauge () which can be screwed into a thread () tapped by a machine tool, and a connecting member () with which the apparatus () can be exchangeably arranged at a tool spindle () of the tool machine, and wherein a sliding clutch () is arranged between the thread plug gauge () and the connecting member (). The invention relates furthermore to a method in which signals () from one or more signals transmitters which are related to screwing-in the thread plug gauge are acquired, in which a reference curve () of signals related to screwing the thread plug gauge into a reference thread is stored, and in which the reference curve () and/or a curve or magnitude derived therefrom is compared with the signals () and/or a curve or magnitude derived therefrom.
