In the technical field, bar turning refers to a field of manufacture where pieces of revolution (screws, nuts, spindle, etc.) are machined by removing material from metal bars, using a cutting tool (in general a knife tool), see clearing.
The parts are machined in small, medium or large series on conventional (cam) or numerically controlled automatic lathes. They are machined one after the other in the bar, the goal being to achieve productivity and high accuracy. It is also generally sought to produce as few chips as possible.
Generally, the parts thus machined undergo subsequent operations (mechanical, thermal or chemical) before being used in the production of subsets.
