Programming industrial sheet metal bending systems requires combining hardware configuration and process requirements. The main steps are as follows:
Task Definition and Parameter Setting
Workpiece Modeling: Design a 3D model of the sheet metal part using CAD software, or import existing drawings and extract key dimensions (such as length, angle, and bending radius).
Process Analysis: Determine the parameters for each process step (such as pressure, speed, and dwell time) based on material properties (such as thickness and hardness) and the bending sequence.
Robot Path Planning: Define the trajectory of the robot for gripping, moving, and releasing the workpiece, avoiding collisions and optimizing motion efficiency.
Offline Programming and Simulation
Use robot offline programming software (such as RobotStudio, RoboDK) to simulate the bending process and verify path feasibility.
Adjust the robot's posture, speed, and acceleration to ensure synchronization with the bending machine's movements, reducing actual debugging time.
Detect potential problems (such as interference and overtravel) through simulation and optimize the program in advance.
Online Debugging and Optimization
Vision System Calibration: Calibrate the intelligent vision recognition module to ensure workpiece positioning accuracy.
Servo System Parameter Adjustment: Correct the bending angle compensation value based on material springback to optimize closed-loop control.
Multi-task Testing: Run mixed production tasks to verify the system's flexibility in switching processes and adjust the MES scheduling logic.
Program Standardization and Archiving
Save the verified program as a template and store it in a database for future use.
Develop programming standards, clarifying parameter naming rules and commenting requirements to improve code readability and maintainability.
Regularly update the program to adapt to new materials and process requirements.
Programming Key Points:
Modular Design: Divide the bending process into independent modules (such as gripping, positioning, bending, and inspection) for easy reuse and modification.
Parameter-Driven: Associate workpiece dimensions with process parameters through variables for quick adjustments.
Safety Mechanisms: Embed emergency stop, limit switches, and other protection logic in the program to ensure equipment and personnel safety.
