Bridge position (micro-connection) cutting process of fiber laser cutting machine
The bridge position cutting process is to ensure that the parts and the plate are not separated during the cutting process and maintain the tiny connection points set in relative positions, so as to ensure the safety of the laser head during rapid movement. This process can automatically add the appropriate number of bridge positions according to the length of the contour. In addition, it can distinguish the inner and outer contours and decide whether to add bridge positions, so that the inner contour (waste material) without bridge positions falls, while the outer contour (parts) with bridge positions are adhered to the parent material and do not fall, thus eliminating the need for sorting.
When the fiber laser cutting machine performs laser cutting, the metal sheet is supported by these serrated support bars. If the cut parts are not small enough, they cannot fall from the gap of the support bars; if they are not large enough, they cannot be supported by the support bars; at this time, they may lose balance and tilt up. When the high-speed cutting head collides with it, the machine will stop at the least and the cutting head will be damaged at the worst.
The above phenomenon can be avoided by using the bridge position (micro-connection) cutting process. When the fiber laser cutting machine is programming the laser cutting of the graphics, the closed contour is intentionally disconnected at several points so that the parts are adhered to the surrounding materials after cutting and do not fall off. These disconnected points are called bridges. They are also called breakpoints or micro-connections. The distance of disconnection is about 0.2 to 1 mm, which is inversely proportional to the thickness of the sheet. Based on different angles, there are different names: based on the contour, it is disconnected, so it is called a breakpoint; based on the part, it is adhered to the parent material, so it is called a bridge or micro-connection. The fiber laser cutting machine uses the bridge cutting process in the cutting process to effectively ensure the smooth progress of the entire cutting process and effectively improve the cutting time. In addition, it can save complicated processes and improve the utilization efficiency of labor.
