Recessing, cutting-out and cutting-off are turning techniques often used.
These techniques permit intricate shapes to be produced.
The recessing (necking, grooving) technique as metal-cutting operation serves to produce
- undercuts for the production of threads,- recesses in circumferential surfaces or hollow parts for grinding of simple and intricate workpieces,
- grooves for intricate machine parts, such as grooves for V-belts, oil grooves, snap rings, annular grooves.
Cutting-out can be used for cylindrical turning of sheet-metal parts and for economical production of rings from solid material with savings in material (cut-out material can be used for further processing). The cutting-out technique as metal-cutting operation serves
- to machine intricate sheet-metal parts which shall be turned cylindrically,- to produce rings from solid material,
- to prevent deformations of thin-walled rings.
The cutting-off (parting-off) technique as metal-cutting opera-tion serves to
- economically produce workpieces from bar stock with the shape, dimensions and surface finish required.
