1 object and significance
1.1 background and significance
after the car is finished welding, it is necessary to polish the weld seam, remove the burrs before painting, remove burrs and further to improve the surface flatness and smoothness. at present, for the case where has high requirements on the grinding accuracy, the main processing method is mainly based on the manual grinding. on the other hand, for some works with high reproducible and relative lower accuracy requirement, the use of industrial robot cooperating with suitable grinding mechanism can improve the manufacturing efficiency and automation of the manufacturing progress while avoid the noise and dust on the worker's body. meanwhile, it also helps to improve the flatness and roughness of the polished surface when machining complex parts with curved surfaces.
with the development of automotive industry, the industrial robot grinding system has been widely used[1]. the current industrial robot grinding system integrates robots, grinding mechanisms, force monitoring and feedback, robot control and grinding trajectory planning, and grinding result evaluation system. it can realize trajectory planning, off-line programming and movement simulation of the grinding progress, realize the constant force control of the grinding process and improve the grinding precision. some robot systems use neural network to transform human experience and the grinding results measured by the laser sensor to further improve the efficiency and precision of the grinding system[2].
