About stylus and probe changing
The range of features and components that must be measured in a typical factory means that manufacturers need a flexible measuring solution. A single sensor and stylus configuration will not be sufficient in most cases.
Is it best to change sensors, or should you change styli?
Stylus changing
Unless you are measuring a simple component, you will need to change your stylus configuration to suit different measurement tasks - e.g. accessing deep features that require long or complex styli, as well as using different tips (sphere, disc, cylinder).
Styli can be changed manually using a threaded connection, but re-calibration is required. Probe systems are now available with a repeatable, automated means to switch styli, reducing manual intervention and eliminating the need to re-calibrate.
Probe autochange systems
A scanning sensor is the most flexible sensor you can fit to your machine, since it can perform discrete point measurement as well as scanning. However, it is not the optimum sensor for more specialised tasks like measurement of soft materials where a non-contact sensor will be best.
In other words, one sensor may not be suitable for all your measurement needs. If the range of features and parts that you must measure demands a range of sensors, then a sensor changing system is essential.
Sensor changing requires a repeatable, automated joint between the probe head or CMM quill and the probes that you want to use. You will also need to store sensors that are not in use.
MRS modular rack system
Many manufacturers find that they need the flexibility of both stylus changing AND sensor changing. The combination means that you will always be using the right sensor and stylus for each task - increasing your measurement accuracy whilst minimising measurement cycle times.
