【摘要】 螺旋搅拌桨是新型工业结晶技术与设备的关键部件之一。基于CAD/CAM技术,研究了螺旋搅拌桨的设计与数控加工技术,利用VC++和UG/OPENGRIP技术开发螺旋桨三维造型模块,快速生成螺旋桨CAD数据模型。根据螺旋桨叶面曲率变化划分出不同的数控加工区域,给出了五轴数控加工的刀轴倾角的确定方法。在DMC2600五轴数控加工中心对Φ1300螺旋搅拌桨实现了数控加工,达到了产品技术要求。更多还原

【Abstract】 The propeller functions as a key part of the new industry crystallizing technique and equipment. The paper discusses the study of the design and numerical control manufacturing technique of the propellers depending on technique of the CAD/CAM,the development of three-dimensional shape mold of propeller using the VC++ and UG/ OPEN GRIP technique, and the faster production of propeller CAD data model. The paper introduces the division of the numerical control processing districts and offers the method determining the cutting tool obliquity in 5-axis CNC, according to the varieties of propeller leaf curvature. Φ1 300 propeller subjected to the numerical control process in 5-axis CNC of the DMC2600 type proves to be up to the product technique demand.更多还原
