A common situation in CMM calibration Ball bars are widely used for checking machine performance. However, engineers sometimes notice that
Why this comparison matters One of the most common questions in CMM calibration is whether to use a ball bar
Why ball bars are widely used Ball bars are one of the most practical tools for evaluating CMM performance. They
Bigger measurement volumes create different challenges As measurement volumes increase, calibration becomes more difficult. Errors that remain invisible in small
tart with the practical question Not every calibration artifact solves the same problem. Choosing the wrong one often creates more
Start with a common mistake People assume calibration artifacts stay accurate forever. They don’t. 1. Surface condition changes over time
Start with a practical question If you are calibrating a 3D scanner, should you use a single ball or a
Not every setup needs a ball bar Despite the usefulness of ball bars in CMM systems and 3D scanning systems,
The common debate In the world of metrology, both ball bars and calibration balls are important tools, but which one
Start with a simple truth If your calibration result looks bad, it’s usually not just one problem. It’s a combination
