ABSTRACT:
In an integrated cutting and tapping tool, a part in the form of a strip is held on a strip support with a hole facing a tap carried by a tapping tool. The bottom dead center point of the tap is detected by a feeler associated with a multiplier lever pivoting about a transverse shaft and pulling on a transmission cable whose free end is detected by position detection means. In this way the position detection means may be moved out of the tool platen, so that the plunger and the multiplier lever constitute an assembly that is easy to integrate under the tapping area. The machining of defective tappings is detected in this way.
