Abstract
A method for gaging a thread can include gaging at least one preliminary thread using a preliminary gage (e.g., a preliminary go gage, and/or a preliminary no go gage). The preliminary thread can be produced in a first step by removing material from the workpiece. The at least one preliminary thread has a preliminary thread profile, and the preliminary thread gage is adapted to the preliminary thread profile. In addition, the method can involve gaging a final thread using a final-thread gage (e.g., a preliminary final-thread go gage and/or a final-thread no-go gage). The final thread can be formed in a second step by plastic pressing-in of the material of the workpiece at least in a section of the preliminary thread profile using at least one thread-forming profile. The final thread has a final thread profile, and the final-thread gage can be adapted to the final thread profile.
