To solve problems of low clamping reliability,machining precision and efficiency during high speed machining of honeycomb,an accurate model that reflects the relationship between machining parameters and clamping parameters is needed to select optimal clamping parameters and to improve machining precision and clamping reliability.A new clamping method on the basis of magnetic field and friction was put forward and defects of the rubber belt were overcome.A finite element model that reflects the relations among machining errors,machining forces and clamping parameters was built,and the clamping parameters were optimized.Based on the proposed model,a thin honeycomb workpiece was machined and results showed that the amount of iron powder is reduced by 70%,clamping reliability is increased,and machining precision of ±0.1 mm is met.
