【摘要】 采用虚拟轴混联机床进行模具自由曲面的精加工,为了提高模具自由曲面的研抛精度和效率,本文论述了自由曲面的分片抛光方法。根据计算机图形信息构造特点,将自由曲面划分为一系列曲面信息与工艺特征相同或相似的曲面片族,相似的曲面片族采用相同的工具和相近的工艺参数进行研抛加工。通过理论计算和仿真验证,此方法能够提高研抛效率。更多还原

【Abstract】 The virtualaxis hybrid machine tool was utilized to polish die free-form surface .In order to improve polishing efficiency and quality of die free-form surface, the paper discusses free-form surface split polishing. According to the construction features of computer graphical information, free-form surface is divided into partition group of surface information and technology information same or similitude and similar surfaces partition group are polished by same tool or similitude technological parameter. This method can improve polishing efficiency of free-form surface by theoretical calculation and simulation.更多还原
