摘要
针对具有大导程、偶数头、光滑连续特点的螺杆钻具马达定子细长内孔,提出了一种用成形立铣刀对称、连续铣削加工的成形方法,阐述了刀工运动成形理论。研究了刀具廓形的设计方法,编制了相关软件程序。通过计算机辅助软件的切削仿真程序,验证了此加工技术的正确性和可行性。
According to characteristics of the PDM＇s stator which has large lead, even heads, smoothand continuous inner helicoids, the article proposed within a continuous inner helicoid and studied the a processing method using finger milling cutter formed theory about the movement of the tool relative to the workpiece. A new method was proposed to calculate the contour of the tool using limited point data of the contour of workpiece and the related software programs was designed. By designing and implementing of computer simulation, the correctness and feasibility of the processing technologyare verified.
