【Abstract】 After making a study on high-speed and high-efficiency machining centers,a new design of machining center,in which the workpiece is fixed,the parallel short chains made up of linear motion actuators are used to drive tools directly for multiple-degree of freedom movement,and the high-speed and high-accuracy drive combines with the highly rigid support,is proposed. Moreover,it also suggests that the fully closed loop feeding system of a. c. permanent magnet synchronous linear motor should be developed, and highly reliable tool change system and pallet change system should be designed.更多还原
