Measurement and Simulation of Cutting Process Influence on Machine Tools Thermal Behaviour

Popis výsledku v původním jazyce

The thermal behaviour of machine tools is important influence affecting final manufacturing accuracy and it can cause more then 50% of overall dimensional inaccuracy of workpieces [1]. Application of software algorithms is the most frequent remedy applied to eliminate the thermally induced errors. Currently, the compensation of thermally induced errors is performed by real time simulation algorithms, including thermal load produced by internal heat sources such as spindle units or ball screw feed drive systems. This fact applies to ordinary polynomial algorithms as well as to advanced real time simulations. However, most of these simulations neglect a very important and hard-to-define thermo-mechanical factor (which is a more appropriate term than a heat source), namely the cutting process. Compared to the research effort on measurement, simulation and compensation strategies related to thermal errors, the influence of the machining process and the influence of the coolant have not been studied with the same intensity [3]. Hence the article deals with the cutting process, which (in terms of thermal behaviour) affects machine tool accuracy markedly and in several ways.
