船用螺旋桨的四轴数控加工方法研究

摘要

As the core power components of the ship, marine propellers, due to their own complex surface , and the high requirements and difficulty of machining accuracy, has been a problem in the processing area. How to use the Axis CNC machine to work out High quality propeller is the issue of our study. Put forward a new method after studying, that was correspond the different characteristics of the marine propeller surface, using the appropriate method to write the processing procedures, implementation of a program and repeated with the fourth week rotation and its rotation symmetry, can easily solve this processing problems.%船用螺旋桨作为船舶动力的核心元件,由于自身型面复杂、加工精度要求高、难度大等因素,一直是加工领域中的一个难题.如何利用四轴联动数控机床加工出高质量的船用螺旋桨是我们要研究的主要问题.经研究后提出一种新方法,即针对船用螺旋桨的各不同特征面,采用适当方法分别编写加工程序,利用其回转对称性并在第四周转动配合下反复执行个程序,可方便的解决这一加工难题.
