System for controlling overlapping in single-layer laser cladding of a shaft-like workpiece

A system for controlling overlapping in single-layer laser cladding of a shaft-like workpiece, comprising:

• an acceleration time calculation module, for obtaining a shaft diameter of the shaft-like workpiece to be processed, a feed rate of a feed shaft and a laser cladding width;
• obtaining a calculation formula of an overlapping rate;
• planning a motion of the feed shaft and a motion of a spindle based on a rotational velocity of the spindle and an S-curve acceleration and deceleration planning algorithm;
• and calculating a feed velocity of the feed shaft to obtain acceleration time of the spindle and acceleration time of the feed shaft;
• a feed shaft displacement calculation module, for determining whether the acceleration time of the spindle is equal to the acceleration time of the feed shaft;
• if yes, calculating a displacement of the feed shaft;
• otherwise, determining whether the acceleration time of the spindle is greater than the acceleration time of the feed shaft;
• if yes, re-planning a motion of the feed shaft according to an acceleration triangle planning method, adding a period of uniform acceleration motion of the feed shaft or reducing a maximum jerk of the feed shaft to make the acceleration time of the spindle equal to the acceleration time of the feed shaft, and then calculating the displacement of the feed shaft;
• otherwise, re-planning a motion of the spindle according to S-curve acceleration and deceleration, adding a period of uniform acceleration motion for the spindle or reducing the maximum jerk of the spindle to make the acceleration time of the spindle equal to the acceleration time of the feed shaft, and calculating a total displacement of the feed shaft;
• and
• a module for adjusting an initial zero position of a laser head in a feed direction according to a difference between the total displacement of the feed shaft and a preset clamping allowance.
