Validation of thermal errors compensation models for different machine tool structures via test pieces

Popis výsledku v původním jazyce

Although real-time software compensations of thermal errors exist, the majority of these models are not sufficiently validated in real finishing operations using a test piece. The accuracy and robustness of the developed models are mostly examined using non-cutting measurements. In contrast, machining tests can be more intuitively understood to evaluate the machine’s accuracy for typical machine tool users. Moreover, the machined test piece represents a suitable method to verify thoroughly the industrial applicability of the developed thermal errors compensation model for machine tool builders. In addition to that, the test piece can be also employed for the evaluation of machine tool thermal errors, obtaining thermally induced displacements at the tool center point over time. It can be consequently applied as input data for compensation model development. The paper presents the authors’ recent research on these issues. Specific test pieces for different machine tool structures are illustrated, e.g., test pieces for validation of thermal error compensation of a gantry-type 5-axis milling centre with a rotary table, a six-spindle automatic lathe and a vertical turning lathe.
