Influence of CNC Machine Tool Technical Condition on the Geometrical Accuracy of Freeform Surfaces

Abstract:

The paper presents results of diagnostic tests for a CNC machine tool used for manufacturing elements with restricted freeform surfaces. Some selected errors possible to identify and estimate in numerically controlled machine tools using a QC20-W Ballbar were described and analyzed. The following parameters were subjected to thorough analysis: roundness deviation, perpendicularity and straightness deviation, cyclic error, backlash and reversal spike. The tests made it possible to carry out a correction of selected components of total tool positioning error and their influence on the process of geometric deviations of curvilinear surfaces produced with CNC machine tools.
