The invention relates to a method and device for controlling a groove of a workpiece
cut by a
robot in offline generation
robot data codes. The method mainly includes the steps that a two-dimensional
graphic design file is read in CAD and groove features are set for the workpiece in the file; a workpiece graph file with the set groove features is opened, a pre-established or existing
robot model and a selected
robot path are used for calculating joint variables of all joints, corresponding to all points of the path, of the robot, and the corresponding robot offline data codes are generated according to the variables; the generated robot offline data codes are transmitted to a controller of the robot, so that the robot is controlled to
cut the groove of the board workpiece. Through the design of the
tail end coordinate position and the posture of the robot and research and development of a robot moving
track algorithm,
servo drive of the robot is controlled, so that the robot reaches the assigned space target, the assigned position and the assigned posture, workpiece groove
cutting is finished, and a traditional undeveloped work mode that the robot is controlled to act depending on manual
visual inspection and teaching
programming is changed.
