Abstract: To form undercut grooves in a work piece, especially to retain turbine rotor blades, in a first step, the grooves are cut such that the flanks of the grooves have a preliminarily desired shape; then, in a second step, a bell-type countersink is moved radially to cut the desired shape of the flanks of the groove. Countersink cutters for the second step include a plurality of groups of cutting bits or inserts secured to posts on a shell, or bell-type countersink, in accordance with the profile to be cut.

A measuring system comprising a linear sensor (12) and a rotary sensor (20) is disclosed. A decoupling unit (11,14,17) decouples the rotary displacement from the linear displacement of a shaft (10). The decoupling unit (11,14,17) has either a first measuring section (11), which is coupled in a fixed manner to the shaft to be measured (10) and tapped by the linear sensor (12) and a second measuring section (17), which is exclusively non-rotatably coupled to the shaft to be measured (10) and is tapped by the rotary sensor (20), or a first measuring section, which is coupled in a fixed manner exclusively linearly to the shaft to be measured and is tapped by the linear sensor and a second measuring section, which is non-rotatably coupled to the shaft to be measured and is tapped by the rotary sensor. In each case, the linear displacement is decoupled from the rotary displacement for the measuring process, permitting high-resolution standard measuring sensors to be used.
