  • System for controlling overlapping in single-layer laser cladding of a shaft-like workpiece
    Patent number: 11833613
    Abstract: A system for controlling overlapping in single-layer laser cladding of a shaft-like workpiece includes an acceleration time calculation module, a feed shaft displacement calculation module and a module for adjusting an initial zero position of a laser head in a feed direction. Using the system, the motions of the spindle and the feed shaft are planned based on an S-curve acceleration and deceleration method. The motion planning is dynamically adjusted considering the overlapping rate and the clamping allowance of the workpiece to be cladded in a feed direction.

  • Method for controlling overlapping of laser cladding, and method and system for dynamically adjusting height of laser head
    Patent number: 11179805
    Abstract: Provided are a method and a system for controlling the overlapping in the single-layer laser cladding of a shaft-like workpiece, and a method, a device and a system for dynamically adjusting a height of the laser head of a laser cladding machine. In the method for controlling the overlapping in the laser cladding of the shaft-like workpiece, the motions of the spindle and the feed shaft are planned based on an S-curve acceleration and deceleration method. The motion planning is dynamically adjusted by comprehensively considering the overlapping rate and the clamping allowance of the workpiece in a feed direction.
