面向PDC钻头的三轴数控机床改进模块研究

The research of three axis NC machine tool improvement module for PDC bit

对常用三轴数控机床进行改进设计以适用于PDC钻头加工。首先分析PDC钻头的加工特征,明确加工工艺。然后根据PDC钻头的实际加工情况和三轴数控机床的特点,设计机床改进模块和控制软件。最后与三轴机床结合,试加工PDC钻头。解决了普通三轴数控机床无法加工PDC钻头和五轴数控机床加工PDC钻头的高成本等问题。

A three axis NC machine tool improvement module is designed in this paper. Firstly, the processing characteristics of PDC bit are analyzed to determine the processing technology. Secondly, according to the actual working condition of the PDC bit and the characteristics of the three axis NC machine tool, machine tool improvement module and control software are designed. Finally, the PDC bit is processed using the improved module. This solved the problems of difficulties for ordinary three axis NC machine tools in processing PDC bit and high cost of machining PDC bits using five axis NC machine tools.
