摘要
为了提高加工中心对复杂工件尺寸的检测效率,提出一种新的加工中心在线复合式检测设计方案,该方案着重论述了检测系统结构、工作原理及软件实现方法等内容。首先基于非接触和接触式检测原理,设计了可以集成于加工中心刀库的复合嵌入式检测装置;进而提出复合式检测的判据,在工件加工过程中,针对不同的检测要求选用不同检测方式,既满足了加工件各特征的检测精度要求,又缩短了工件的整体加工检测周期,提高了在线检测效率;最后通过复合式检测数据融合和后处理数据分析,给出工件特征的加工质量分析报告。为了检验该方案的可行性,以步距规为检测对象,根据步距规的使用参数和精度特征,经复合式检测后,生成了二维和三维工件特征的检测结果,证明了该设计方案的合理性,为加工中心在线检测技术提供了一种新的方法。
To improve inspection efficiency of machining centre for complex workpiece size, an on-line composite in- specting design method in machine centre was presented, which focused on the structure, working principles and software implementation of the inspection system. Based on the principles of non-contact and contact inspection, a composite inspection equipment with embedding function was designed which could be integrated in tool magazine. Thus the criterion of composite inspection was proposed. To satisfy the inspection accuracy demands for different features of workpieces and reduce the entire process cycle, different inspection modes were selected for different de- mands in machining process, which significantly improved on-line inspecting efficiency. Through the data fusion and the post-process data analysis, the machining quality analysis report for workpieces was given. To prove the method＇s validity and feasibility, a step gauge was taken as an object to generate 2D and 3D inspection results ac- cording to the operation parameters and the precision features, and the rationality of proposed method was validated. It provided a new method for on-line inspection of machining center.
