Design on Mechanical System for Optimal Cutting Movement Trajectory of High-Efficacy Stone-Sawing Machine

In this paper, the cutting movement system of stone-sawing machine is analyzed. The optimum design of systems with optimal cutting movement trajectory is conducted. The mathematic equations of the optimal system parameters are established. The design schemes and computing methods of parameters of systems with optimal cutting movement trajectory are given. The key technical problems are solved, which include the choice of the offset of the swaying wheel, of the clearance between sliding block and the bottom of the gliding groove, of the elasticity coefficient k of the spring. A mechanism with eccentric swaying wheels, whose effective cutting stroke is nearly 100%, is developed. And the theoretic and technical basis for optimal design are offered.
