Repeatability in Precision Machine Tools

Repeatable Machine Structure

Repeatability is one of the most important elements in precision machine tool design. The aim is to make a mechanical structure that is stiff and repeatable. Having a stable and stiff mechanical structure is the basis for a high precision machine tool.

Finite Element Analysis

At Cranfield Precision we design high precision machine tools with stiff and repeatable structures through advanced finite element analysis techniques and by obeying the key principles of precision machine design.


Once you have a stiff and repeatable mechanical system that will consistently repeat to a demanded position advanced control system and error compensation techniques can be applied to correct any measured errors. 


Precision metrology techniques are used to accurately measure machine error motions. The combination of a stiff repeatable structure, precision metrology and error compensation techniques produces a very accurate precision machine tool.
