Kinematics Analysis and Simulation of A New Spatial Linkages Cutter

A new spatial linkage mechanism was designed for three dimensional modeling construction and motion mechanism analysis in terms of current defects in traditional cutter transmission device which adopted gear mechanism combining with planar crank-rocker mechanism.The output displacement,speed and acceleration equation of motion were obtained,and the motion diagrams of cutter using spatial linkages mechanism were simulated.The simulation results showed that the mechanism could achieve the smooth output of the cutter,it would establish the basis for the next dimensional synthesis.
