Anticipatory Systems in Thermal Errors Compensation (TEC) of Machine Tool

The errors of machine tools on product arise from some source types which directly affect the structure of machine, the tool, the piece and the translation systems. An accurate design can control many of these sources but the thermal ones are yet critical. Many solutions were proposed to control them from the design state either by hardware or by software. The software methods are based on processing the temperature signals of the structure till to compensate the error between piece and tool. The AA. Have performed many particular solutions and in the recent years they have experimented TEC by fuzzy system whose rules vary by a neural network or by an anticipatory model.
