This paper briefly introduces laser cutting head asway mechanism of fracture splitting notch processing machine

and has achieved a series of dynamics simulations towards it

based on the simulation results

rational hydraulic parameters(optimum hydraulic pressure is 2.5Mpa

throttle valve’s discharge coefficient is 0.2) are determined

physical cutting tests are also carried out

which indicates that asway mechanism works with stability

reliability and good cutting effect under the condition with appropriate cutting processing parameters. Meanwhile

this paper introduces servo electromotor driven asway mechanism

and has accomplished kinematics simulations towards the improved asway mechanism

the simulation results show that the improved asway mechanism works faster

asway angle is more accurate

and adjustment of asway angle is more convenient

which provides reliable theoretic basis for optimizing structure of the laser cutting fracture splitting notch machine.
