Title:
ACTIVE SPINDLE POSITIONING
Document Type and Number:
WIPO Patent Application WO2001087539
Kind Code:
A3
Abstract:
The invention relates to a method for adjusting a position during the active positioning of a spindle, said adjustment being driven by control variables that are created on the basis of actual values of the position of a rotatable spindle. In addition, the creation of said control variables is based on corrective values that are calculated in advance, using the spindle stresses that are expected during operation. In the case of a machine tool for machining processes for example, the invention increases machining accuracy, surface quality and productivity.
