Hi,
The CMM is a Mitutoyo Crysta Apex and the touch probe is from Renishaw with scanning option. This is a very basic question but I'm fairly new to CMMs. In the attached picture on the left, the stylus touches the workpiece perpendicular to the surface - an ideal situation. However, on the right, the smaller the angle "a", the larger the measuring position error. What kind of magnitude of error are we talking about here? I have heard that "a" should always be as close to 90 degrees as possible but as the head indexing step is 7.5 degrees, it is not always possible.
