- Abstract:
- The paper deals with the active error compensation effected by using links or components, made from piezoactive (piezoelectric or magnetostrictive) materials. It is shown that by implanting of active links into the technological chain of the measuring equipment both static and dynamic errors can be sufficiently reduced. Some considerations according to new approach to error compensation circuits and actuators are presented. Compensation covers not only generally accepted measurement systems, but also opens new ways of increasing the accuracy of such typical components of technological machines as beddings, slideways, fixing and datum keeping surfaces. Two- and three-dimensional correction methods and means are presented.
