Laser processing and flexible manufacturing systems have good compatibility. The combination of the two to form a laser flexible processing system, in mutual cooperation with each other under the conditions of good will certainly receive extraordinary results and achieved good returns.
With the further study of the interaction between laser and material, laser processing technology will also be widely used in the flexible manufacturing system. To achieve flexible and systematic laser processing mainly refers to the laser processing head can be flexible and guide the laser beam to reach the parts to be processed position. Laser processing machine tools from the complexity of the parts can be processed, but also two-dimensional and space-dimensional three-dimensional laser processing. High-power laser three-dimensional processing is the future direction of laser processing direction, in order to achieve the flexibility of laser processing, the three-dimensional laser must use a moving optical system. High-power three-dimensional YAG laser processing system usually uses robots (or robots) with optical fiber for beam transmission, the robot holding the laser head to complete a variety of sports. The laser light is transmitted to the laser processing head through the optical fiber to reach the surface of the workpiece. In this type of processing system, the beam transmission and focusing characteristics are unaffected by the processing position.
The robot as an important part of laser flexible processing system, the stability of the movement status directly affects the processing quality. For high-power CO2 laser, it is through a set of optical lenses (mirror group) for transmission. These mirrors are mounted on a multi-axis (typically 5-axis) CNC machine tool. The laser light is emitted from the laser and passed through several mirrors to the laser processing head. With the processing position changes, the processing machine has driven laser processing head movement. As a result, the distance between the lenses and the travel of the laser beam constantly change, and these changes will affect the energy distribution of the laser beam and changes in focusing characteristics, thus affecting the processing. At present, these two processing systems are widely used.
