A laser solid forming/repairing system is developed based on Motoman SSF-2000 robot where high-precision robot powder feeding system, real-time vision system and inert gas protection system are integrated altogether and high-precision forming and repairing process can be achieved. The computer communicates with the robot by utilizing MotoCom32 communication interface to control all the processing parameters about the automation of the laser processing operation. When a simple part is formed or repaired, the system programs by the way of controlling teaching plate. When a complex part requires forming or repairing, the control system reads the DXF file produced by AutoCAD which records the geometric information of the curve, and calculates the curve to a large number of short lines to meet the accuracy requirement. By the real-time communication between computer and the robot, the control system can update the motion trail data. Experiments show that the system can complete the processing of laser solid forming and repairing excellently.
