Straight-line flying cutting of a laser cutting machine refers to a state where the cutting surface moves linearly during the cutting process but is not completely perpendicular to the direction of the laser beam. The main causes of straight-line flying cutting are as follows:

　　1. System Software Issues of the Laser Cutting Machine

　　Straight-line flying cutting of a laser cutting machine is generally caused by software program errors or incompatibility between the system software and the laser cutting machine. When this occurs, the problem can be resolved by modifying the program or reinstalling the laser cutting machine software.

　　2. Laser Generator Issues

　　Straight-line flying cutting can also be caused by problems with the laser generator of the cutting machine, such as insufficient output power of the laser generator or poor beam quality. In such cases, first check whether the laser generator is operating normally, then replace it with a laser generator of appropriate power.

　　3. Machine Tool Issues

　　If the problem lies with the machine tool itself, a comprehensive inspection of the machine tool is required. If the machine tool itself is functioning properly, then check whether there is an issue with the CNC system or software. If the CNC system and software are working normally, the straight-line flying cutting issue can be resolved by replacing the machine tool with a new one or reinstalling the laser cutting machine software.
