Software correction of volumetric geometrical errors of multi-axis systems based on laser interferometric measurements

Аннотация

The article continues description of geometric errors laser correction for multi-axis NC-systems–CMMs and machine-tools. The Kalman’s concept of observability and controllability is applied to the method. In order to observe the multi-axis system a versatile laser measuring system is used, and in order to control the system a program postprocessor is proposed, introduced between CAD/CAM and NC-systems.
