The spray model is the basis for spray trajectory optimization, which reflects the accumulation of paint on the surface to be sprayed. In this paper, a modeling method of torch model and its application in plane spraying trajectory optimization are studied. According to the physical model, a simplified mathematical model is used to describe the flow distribution function of the paint flow in the torch flow field. And from the above function, further obtained the spray coating deposition *** to the simulation experiment and the actual spraying of the data were compared to prove the correctness of the model.

An articulated robot cooperated with a positioner is widely used in the field of intersecting pipes welding. In order to resolve the bottlenecks in productivity caused by the burdensome manual teaching process, this article presents an algorithm to generate motion codes for industrial robot to weld intersecting pipes. A unique welding scheme that simplifies welding technology complexity is introduced and adopted. Based on the geometrical model of intersecting pipes with the most complex intersecting mode, the welding trajectory planning is developed which contains posture planning of the welding torch and weaving welding control strategy. Then the welding trajectory is decomposed into the motion of the robot torch and the positioner, and the spatial relationship between the torch and the robot base is described with homogeneous transformation matrix. Finally, an algorithm flow chart with welding speed control strategy is provided for generating robot motion codes. Simulation and welding experiment verify the feasibility of the algorithm.

This paper is concerned with a new methodology which is designed to auto-generate the robotic trajectory for thermal spraying process. Based on it, a software package named Thermal Spray Toolkit is developed and integrated in the main frame of off-line programming software RobotStudio (TM) (Product of ABB Company, Sweden). This toolkit implements the robotic trajectory planning in an interactive manner between RobotStudio (TM) and the finite element analysis software (FES). It allows rearranging the imported node index created on the surface of workpiece by FES and in turn generating the thermal spraying needed robot trajectories. Several parameters in thermal spraying, such as scanning step and torch-substrate relative velocity which have major influence on the coating deposition, are considered in the trajectory generation process. Experiment is carried out to check the reliability of the generated robot trajectory.

The strategy of robot trajectory generation is still an experience issue in industry applications. This paper introduces a mesh-based method to generate different patterns of trajectory for thermal spraying applications. In this method, the appropriate mesh is generated on the coating surface of model in CATIA, the mesh information including the node index, position and orientation is then imported into an off-line programming software RobotStudio(TM) (Product of ABB Company, Swiss) by a secondary development user interface. In the environment of RobotStudio(TM), robot targets are generated according to the mesh information and user-defined robot relative parameters. The different trajectory patterns formed by varied execution order of robot targets are simulated in RobotStudio(TM). By analyzing the real time speed of Tool Center Point (TCP), the most appropriate trajectory can be determined. Finally, the recorded TCP speed is considered as the displacement of thermal source in ANSYS, the thermal distribution of the workpiece during the thermal spray process is analyzed accordingly in this article.

off-line programming provides an essential link for CAD/CAM. This paper introduced the principle of developing off-line programming system for laser re-manufacturing. Task and information flow of off-line programming for laser re-manufacturing robot was analyzed and the software structure of off-line programming based on commercial CAD software was constructed. The off-line programming system developed in this study includes 3-D solid model design, direct slicing for obtaining path data, graphical simulation of the robot and its workcell, kinematic model of the robot, motion planning, and creation of the control program for manufacturing process. The CAD software was used to design models of robot, workpiece, coaxial nozzle, and workspace. Through the application programming interface provided by the CAD software, the VC++ and ATL were chosen to develop such modules as direct slicing for obtaining path data, path planning, process specification, and control program automatic generation. The FANUC Roboguide software was used to realize graphical simulation. By direct slicing, the position and orientation data of robot end-effector was determined. The results show that the proposed system can be applied in laser re-manufacturing robot for manufacturing operations.

A flexible remanufacturing system based on arc weld robot is established which consists of three subsystems: 3D laser measuring subsystem, modeling subsystem and off-line programming subsystem. The whole remanufacturing procedure consists of a several steps, such as work piece measuring, locating, modeling, welding program generating and surface depositing. The surfacing program consists of automatic delamination, automatic weld bead planning and welding parameter generation. The system can be easily employed to an automatic remanufacturing of work piece of various state of surface damage. Test remanufacture are carried on damaged plate, damaged column and worn axletree, and the results show the system is feasible.

This paper presents methodologies to discretize nominal robot paths extracted from 3-D CAD drawings. Behind robot path discretization is the ability to have a robot adjusting the traversed paths so that the contact between robot tool and work-piece is properly maintained. In addition, a hybrid force/motion control system based on Fuzzy-PI control is proposed to adjust robot paths with external sensory feedback. All these capabilities allow to facilitate the robot programming process and to increase the robot's autonomy. (C) 2012 Elsevier Ltd. All rights reserved.
