Process monitoring during laser cutting


For automated systems in 24-hour operation, sensor and control technology is becoming increasingly important. Today, the modern user wants to be able to produce carefree in three-shift operation - without having to monitor the operating state manually. Sensor technology for process monitoring and control ensures compliance with the specified parameters and cutting qualities. Starting with absolute drift-free distance measurement, detection of protective glass contamination, monitoring of piercing and laser cutting process monitoring, a wide variety of sensors provide the necessary security for automated processes in highly productive plants.

Typical applications in laser cutting:


There is a risk that the cut interruptions when the process parameter deviates at higher cutting speeds and/or material strengths. The process adapter detects cutting interruptions and stops the machine to prevent subsequent damages and rejects. 

The monitor detects plasma generation and if the observed reading is outside normal limitations, the monitor will stop the process; indicating to the user an error. 

Applications
Monitoring the cutting process

The cut quality is at risk if plasma builds in the die clearance. The process adapter detects plasma building in time and sends a command to stop the machine. The rejection of parts can be avoided by e.g. reducing the cutting feeder. 

Lens break sensor
Lens monitoring

A high-quality sensor system monitors the state of the CO2 lenses that are pressurized with high cutting gas pressure. It detects and reports errors that occur to the machine controls and provides immediate shut down of the laser and the cutting gas supply. Expensive rejects or consequential damage can thus be prevented, e.g. the effort to clean and readjust the beam path after a lens break. The monitoring systems have already successfully proven themselves in over 5000 systems.

Detecting of cut interruption in time

There is a risk that the cut interruptions when the process parameter deviates at higher cutting speeds and/or material strengths. The process adapter detects cutting interruptions just in time. Stopping the machine and/or repeat function can prevent subsequent damages and rejects.
