The calibration of the HandyPROBE stylus is a key step to a good project.
There are two modes in which the calibration of the probes can be done: static and dynamic modes. As we never really know how stable the environment is, the dynamic mode should remain the 1st choice for most of the probe calibrations.
However, you need to follow some basic rules when calibrating in dynamic mode.
The rules are the same as when you apply targets on a part prior to the inspection.
- Use enough targets: The system needs at least 3 targets to operate, however using more targets will help stabilize the reference.
- Distribute the targets in the volume: The targets should not be too close to one another.
- Cover the 3 axis (XYZ): Having targets in the 3 axis will help the C-Track to reference the movement of the probes in those 3 axis.
- A bigger span leads to a more stable reference: Try to cover at least the movement of the probe during the calibration. (i.e: the size of the probe in every direction).
You might know about calibration cones that have several targets on them. These reflectors should not be used as your only targets for the calibration. The targets are too close to one another and the span is very small. This leads to an unstable reference and the targets do not cover the 3 axis.
