Kinematics Analysis of Double-Cutter & Double-Surface Symmetrical Machining Tool for Large-Scale Marine Propeller

Abstract:

The traditional large-scale marine propeller processing equipments have such disadvantages as single-surface machining, propeller blade vibration, poor stiffness, repeated clamping and long processing time. The method of double-cutter & double-surface symmetrical machining is proposed for large-scale marine propeller based on the parallel-serial mechanism. The processing method can overcome proposed disadvantages, and improve machining efficiency and accuracy. The structural design of the processing equipment is introduced and the coupling kinematics parameters of the parallel spindle platform are analyzed. The inverse kinematics solution and improved forward kinematics solution are discussed in detail. And the forward kinematics solution can solve a troublesome problem about the selection of good initial parameters. A simplified prototype is built to verify the solution method which could be used in the future actual application as a foundation.
