Prediction and analysis of material removal
— The robotic belt grinding system includes a robot motion unit (ABB IRB4400-60/1.96), a force control unit (ATI Omega 160) and an abrasive belt grinder unit. During the material removal process, the robot holds the workpiece in contact with the rotating contact wheel of the grinder and feeds it slowly, which follows the predetermined off-line path.
