The workpieces are located no the base of the fixture and clamped before starting the operation. These fixtures are normally mounted on the nose of the machine spindle or on a faceplate and the workpieces held them. Against this, a capstan and turret lathe can be easily adapted for repetition work on account of the multi-cooling arrangement and use of transverse stop this increases the rate of production. Gigue, (French: “jig”) popular Baroque dance that originated in the British Isles and became widespread in aristocratic circles of Europe; also a medieval name for a bowed string instrument, from which the modern German word Geige (“violin”) derives.
