Background
Machine tool accuracy is affected by a variety of environmental and physical factors, including the thermal expansion of components, defects in the guide rails and bearings,
and other geometric errors that occur during manufacturing.

Designers can mitigate against these sources of error by applying several strategies. Two ways of improving machine tool accuracy
are: optimising the assembly process and compensating for thermal errors, and using high-performance position feedback and motion control.

By using laser calibration systems for quality control testing, assembly
errors during the machine build are reduced, and accuracy verification and optimisation can be performed at the factory before shipment, which improves machine tool quality.

In the
design of machine tools for applications demanding superior motion control, closed-loop optical encoder systems are often chosen to provide direct position feedback from the linear axes.
