Original Abstract
This contribution assesses the possibilities of application of conventional compensation technology on a small three-axis vertical machining centre. Small CNC machine tools are intended for manufacture of small workpieces with dimensional accuracy of up to 0.001 mm. To achieve the required accuracy and reproducibility of manufacture, a variety of software compensations are deployed on machines. The aim of these compensations is to eliminate errors caused by deviations in the machine geometry, thermal expansion and dynamic compliance of the machine tool. In order to increase dimensional and geometric accuracy of workpieces, this study tested and evaluated methods to activate geometrical compensations such as approach to the desired position and volumetric compensations. Calibration and verification of set compensations were validated by testing geometric accuracy of machines using the devices Ballbar, Laser interferometer and LaserTRACER. Conclusions drawn from the performed study verified deployment of compensations on small CNC machine tools.
