Abstract

The utilisation of 2D grid encoders is a very adequate tool for machine tool calibration and dimensional metrology, offering theoretical accuracies down to few micrometers and making them suitable for dynamic, static or even thermal drift tests. In spite of this, studies on their thermal behaviour are very rare to find in the literature. In this paper an experimental technique to characterise the thermal influence in one of these 2D grid encoders is presented. The proposed technique uses a X-Y plane mirror laser encoder system with nanometre resolution and independent thermal sensors in each axis. This 2D laser encoder is used as a reference device to characterise the grid encoder behaviour. The preliminary setup, experiments carried out and results are explained.
