CONSIDERATIONS REGARDING THE NUMERICAL COMMAND MACHINES
Journal Title: ISB-INMA TEH AGRICULTURAL AND MECHANICAL ENGINEERING - Year 2017, Vol 0, Issue 1
Abstract
The paper presents some considerations on current stage of numerical command machines. Numerical control has appeared before inventing microprocessors used in current computers, due to necessity of developing machine-tools able to perform complex parts of high precision. US Air Force boosted their development, due to financial resources they made available for stimulating the researches.US Air Force needed to improve the structure of jet planes. Initially, the first CNC machines made use of electronic lamps and vacuum. These machines had a series of disadvantages, such as: they produced excessive heat, occupied a rather big space, had low reliability, could perform only one operation. The next generations of machines were endowed with transistors (that replaced the electronic tubes) and the controller took small room. Nowadays, the numerical command machines are based on technology of microprocessors and current computers.
