Objective
This project resulted in the development of an off-line programming system for arc welding robots that significantly reduces the time it takes to train a robot, greatly improving the efficiency of the production environment.
A set or rules with welding- and robotics-specific know-how are incorporated in the new system, which provide the programmer with helpful support.
The steps covered are:
- Analysis and classification of the welding geometry based on CAD data
- Determination of welding parameters
- Planning of the welding sequence under process-specific and manufacturing aspects
- Planning of the robot's motion during welding and between welding
- Positioning of external robot axes and resolving of kinematic ambiguities
- Storage of the robot program in a relational data base.
The system uses standardization interfaces such as IGES, SQL, and X-Windows, and is open wherever possible to make replacement or extension of modules easy.
THE OVERALL OBJECTIVE OF THE PROJECT IS THE REALIZATION OF A PROTOTYPE SYSTEM FOR OFF-LINE PROGRAMMING OF ARTICULATED ARM ROBOTS AND ITS IMPLEMENTATION IN AN EXISTING CAD/CAM ENVIRONMENT. WITH THIS SYSTEM, IT IS INTENDED TO SIMPLIFY THE GENERATION OF OPTIMAL EXECUTABLE ROBOT PROGRAMS FOR THE WELDING PRODUCTION OF LARGE WORKPIECES WITH RECURRING WELDING PATTERNS. ON THE BASIS OF THE CAD-WORKPIECE-MODEL, KNOWLEDGE BASED MODULES HAVE TO SELECT AND COMBINE EXISTING WELDING PATTERNS OUT OF A DATABASE AND GENERATE A NEW ROBOT PROGRAM FOR THIS SPECIFIC WORKPIECE.
SIMULATION MODULES ENABLE CHECK AND CORRECTION OF DETECTED MALFUNCTIONS OF THE EXPERT-SYSTEM AS WELL AS DETECTION OF INTERFERENCES BETWEEN THE ROBOT, WORKPIECE AND THE ENVIRONMENT.
INACCURACIES ASSOCIATED WITH THE MECHANICAL STRUCTURE OF THE ROBOT AND THE PERIPHERICAL COMPONENTS HAVE TO BE COMPENSATED WITH OFF-LINE CORRECTION MODULES AND SPECIFIC CORRECTION STRATEGIES. SENSOR FUNCTIONS AND STRATEGIES ADAPT OFF-LINE GENERATED AND CORRECTED ROBOT PROGRAMS ON-LINE TO EXISTING WORKPIECE TOLERANCES. BY THE USE OF SUITABLE MENU TECHNIQUES, THE SYSTEM'S DEGREE OF AUTOMATION AND FLEXIBILITY IS TO BE TAILOR-MADE TO THE SUPERVISORS OF THOSE MANUFACTURING SYSTEMS, I.E. SKILLED WELDERS.
