MSG – Schmallenberg – Germany. The assessment of effective straightness of bars, wires, tubes and/or profiles is not trivial. This is mainly situated in the effects of gravity, dynamics and external contact forces introduced by the measurement apparatus itself.
For example, a rod product placed on a ref- erence table will be influenced by its own weight and contact forces like friction. On reference tables the straightness is mainly measured with feeler gauges. In case of
rotating the product radially the results are varying a lot.
The patented GMS-Sprofile developed
by MSG Maschinenbau GmbH solves this problem. The solution is quite simple: measuring forces in all existing points and all directions. Bending errors due to vertical own-weight and horizontal contact forces (e.g. friction) are eliminated. That’s why
this system measures an undiscussable, absolute objective – a so called effective straightness value (figure 2).
