摘　　要：针对回转舱体零件工序模型构建过程中人工重复性工作量大、效率低、易出错的问题,提出一种基于设计模型分段的车削工序模型快速构建方法。通过定义分段规则将设计模型拆分,然后计算分段内外包络值,添加余量构建分段包络体和车削体,利用布尔操作得到车削工序模型;并以典型回转舱体为例,对模型的有效性进行了验证。结果显示,所提方法可实现回转类零件车削工序模型的快速构建,可为零件车削数控加工提供技术支撑。A fast generation method for turning process models based on splitting design models is proposed to address the issues of high repetitive workload,low efficiency and error prone in the construction of process models for rotating cabin models.Splitting the design models by defining segmentation rules,calculating the inner and outer envelope values of the segments,and add margins to construct segmented envelope bodies and turning bodies,then use Boolean operations to obtain the turning process models.Finally,the effectiveness of the proposed method was validated using a typical rotating cabin as an example,achieving rapid construction of the turning process model and laying the foundation for CNC machining of parts.
