Abstract
Thermal errors represent a design issue of numerically controlled axes, due to their negative influence on the working accuracy of shop floor devices. This paper proposes an approach for simulating the heat transfer and thermal expansion based on computer aided software. The results achieved are used to evaluate the s-domain transfer function (or the relationship between temperature and displacement). The research can be used for the design, simulation and validation of various control techniques.
Keywords
