The operation of the system is based on the principle of scanning the inner surface of holes with a rotating laser triangulation sensor.
Main components of the system:- Laser triangulation probe(s) RF609-Wi-Fi Series;
- Industrial tablet with software.
- The laser triangulation probe is installed in the spindle of the CNC machine, see the picture 1.
- The CAD file of the controlled tube sheet is uploaded into the program on the tablet.
- The operator enters the spindle rotation speed, the probe feed rate and the sequence of measuring the tube sheet holes into the machine program and the system program.
- The tablet is switched to data reception mode, and the scanning program is launched on the machine.
During the measurement process, the machine sequentially, in accordance with the selected algorithm, inserts a rotating laser probe into the controlled hole. The laser probe transmits measurement data to the tablet, and the tablet software calculates the geometric parameters of each hole and displays them in a graphic color code. After completing the measurements, the operator generates a report.
