将特征技术引入夹具设计 ,提出基于加工特征的、面向夹具设计的工艺模型和基于装夹特征的装夹模型 ,介绍了基于实例与基于规则推理相混合的装夹模型提取方法和装夹元件的选择方法 The feature technology is introduced into the fixture design. The process model based on the machining features, the fixture-oriented process model and the clamping model based on the clamping feature are proposed. The extraction method of the clamping model based on the example and the rule-based reasoning is introduced. method
