Based on the system, a seri- als of processing experiments were carried out and the effects of grinding angles, robot moving speed and grinding path on the surface quality were studied and the suitable grinding parameters were ob- tained. By using the parameters robotic grinding experiments on the surfaces of the mould manufac- tured by plasma spay tooling were executed. T he experimental results indicate: keeping suitable grinding pressure and choosing reasonable grinding angle, robot moving speed, feed rate, ideal sur- face quality can be obtained by adopting the established robotic grinding system and the platform can be applied in grinding process of the moulds manufactured by spray tooling and general moulds.
