You can measure roughness on a Global S Chrome CMM with an LSPX 5 HD probe head, FDC 800 controller, and PROFILER R sensor. The following diagram shows how a CMM with a PROFILER R sensor measures roughness:
Example of a roughness measurement
A - 24V Power Supply
B - Calibration Artifact with Holder
C - CMM
D - FDC 800 Controller
E - PC-DMIS Automation
F - Computer running PC-DMIS
G - USB Connection
H - Bluetooth Module
I - Serial Bluetooth Communication
J - PROFILER R Sensor
K - Workpiece
You can define the roughness measurement for a device that measures tactile roughness and evaluates surface parameters according to these geometrical product specifications:
DIN EN ISO 4288:1998-041
DIN EN ISO 4287:2010-072
DIN EN ISO 13565-1:1998-043
