Text 13 semi-automatic machine tool

A semi-automatic machine tool is a type of machine tools in which part of the opera­tions (transport or auxiliary) is carried out by a human worker and all processing opera­tions are performed automatically without human assistance. A fully automatic machine tool performs all types of operations (including transport, auxiliary and processing) au­tomatically without human assistance. Human worker only controls its operations. First fully automatic machine tools had limited capabilities and could perform only 1–2 pro­cessing operations. They were used for production of separate parts, for example screws of identical shape.

M achine tools equipped with a reprogramming control system can perform several operations instead of one. They can be easily adopted for different modes of operation by changing the program. Even during the operations such machine tools independently change the cutting rate or drilling depth, i.e. the technological processing mode.

Machine tools equipped with a reprogramming control system are multi-purpose and are being used extensively in automatic production lines where they also perform the func­tion of ready production control.
