Measuring surfaces – tactile or contactless?

Have tactile measuring methods become obsolete?

These questions are constantly asked by those responsible for quality assurance and production. The fact is that, especially on or in the production line, optical measurements and inspections are increasingly taking place, as these technologies work significantly faster in many cases. However, the choice of technology is complex. This article helps to evaluate the relevant aspects for the correct measuring strategy.

The e-book discusses among other things:

Has tactile metrology become obsolete?
Are tactile surface measuring instruments discontinued models?
Or does optical technology reach its limits when high accuracy is required?
What are the different optical measuring methods actually based on?
And what about the traceability of the measuring results with optical methods? Are there already standards here?
Pros and cons: What are the advantages and disadvantages of the two technologies?
