Project: Metrology for movement and positioning in six degrees of freedom

Mechatronic motion systems are the basis of most production systems, ranging from machines for wafer scanners in semiconductor production, to robotics and coordinate-measuring machines. However, it is difficult to position these systems to the required precision under harsh and changing conditions, and this can lead to a trade-off between fast measurements and accuracy. This project will develop measurement instruments to support traceable six degrees of freedom (6DoF) measurement. 6DoF refers to the ability of an object to move freely in three-dimensional space. The project will use interferometry techniques to establish a direct link to the definition of the metre. Traceable measurements of position, angle and straightness will be made accurate to the nanometre. Novel hardware and improved sensor systems will improve nano-positioning. This will benefit industry through more efficient production processes, reducing the number of defective parts and this will lead to savings in raw materials and time.
