Laser cutting processing with high cutting precision, quick cutting speed, low thermal effect, no pollution, no noise, etc, in the automotive, Marine, aerospace, and are widely used in electronic industry.
Laser cutting processing quality and the relative position between the laser focus and artifacts have close relations, ensure the laser focus and the reasonable relative position between the cutting object is one of the key to ensure the quality of laser cutting processing.
the focus of the laser focus position cannot be directly measured, but can be by indirect methods. For a laser cutting processing system, the focus position is determined by the focus lens in the optical focus, so in the case of focusing lens must be its position is the same ( Regardless of the heating effect of the focusing mirror) , so you can focus lens and through testing the relative position between the processed object to indirectly detect the location of the relationship between focus and processed object.
laser focus and the relative position between the processed object by inductance displacement sensor and capacitance sensor to detect, each have advantages and disadvantages in use. Inductance sensor response frequency is low, is not suitable for high speed machining and like! D processing this non-contact detection of occasions; Capacitance sensor, has fast response speed, high precision, but in the process of using the nonlinear and the laser cutting processing of plasma cloud and the influence of spray slag
