航空蒙皮类零件加工模具的特征检验与质量评价

Feature Inspection and Quality Evaluation of Air Skin Parts Processing Mold

将传统蒙皮类零件加工模具的制造与检验的模拟量信息传递模式转变为数字化模式,是现代飞机制造的必然要求。对于影响零件制造质量的多类型模具的特征检验,应制定测量方案,获取检验特征的数据,并结合理论模型的检验分析方案,在特征匹配和数据对齐的基础上分析偏差指标的数据,从而实现模具加工质量的数字化评价。分析结果表明,通过统计与计算复杂型面和各类定位与制造基准的偏差,可实现加工质量的数字化综合评价。

It is an inevitable requirement of modern aircraft manufacturing to transform the analog information transmission mode of manufacturing and inspection of traditional skin parts into digital mode.For the feature inspection of multi types of molds that affect the quality of parts manufacturing,the measurement scheme should be made to obtain the data of inspection features.Combined with the inspection and analysis scheme of theoretical model,the data of deviation index should be analyzed on the basis of feature matching and data alignment,so as to realize the digital evaluation of mold machining quality.The analysis results show that the digital comprehensive evaluation of machining quality can be realized by acquiring the statistics and calculation of the deviation index of complex surface and various positioning and manufacturing benchmarks.
