In machining, a tool bit is a non-rotary cutting tool used in metal lathes, shapers, and planers.Such cutters are also often referred to by the set-phrase name of single-point cutting tool, as distinguished from other cutting tools such as a saw or water jet cutter.
With its parent company, it ceased operations following the First World War, when restrictions on German aviation were created by the Treaty of Versailles.In 1921, the factory was purchased by Heinrich Lübbe, who is said to have assisted Anthony Fokker in the creation of the pioneering Stangensteuerung synchronization gear system during 1914-15, and re-commenced aircraft construction for export.
Henry Maudslay's early screw-cutting lathes of circa 1797 and 1800.. A screw-cutting lathe is a machine (specifically, a lathe) capable of cutting very accurate screw threads via single-point screw-cutting, which is the process of guiding the linear motion of the tool bit in a precisely known ratio to the rotating motion of the workpiece.
The Garrett ATF3 (US military designation F104) is a 3-spool turbofan engine developed at the California division of Garrett AiResearch.Due to mergers it is currently supported by Honeywell Aerospace.
The Pratt & Whitney JT3D is an early turbofan aircraft engine derived from the Pratt & Whitney JT3C turbojet. It was first run in 1958 and was first flown in 1959 under a B-45 Tornado test aircraft.
The Aermacchi or Macchi MB-326 is a light military jet trainer designed and produced by the Italian aircraft manufacter Aermacchi.It is one of the most commercially successful aircraft of its type, being bought by more than 10 countries and produced under licence in Australia, Brazil and South Africa.
The Aermacchi M-346 Master is a family of military twin-engine transonic advanced jet trainers and light combat aircraft.Originally co-developed with Yakovlev as the Yak/AEM-130, the partnership was dissolved in 2000 and then Alenia Aermacchi proceeded to separately develop the M-346 Master, while Yakovlev continued work on the Yakovlev Yak-130.
A lead screw is sometimes used with a split nut (also called half nut) which allows the nut to be disengaged from the threads and moved axially, independently of the screw's rotation, when needed (such as in single-point threading on a manual lathe). A split nut can also be used to compensate for wear by compressing the parts of the nut.
