摘要
计算机技术和仿真技术的迅猛发展推动着薄壁零件数控加工工艺由不成熟的工艺发展蜕变为工程科学。在此过程中,薄壁零件数控加工技术研究由传统的经验研究转变为科学的"定量分析"。薄壁零件存在的问题是刚性差、结构较复杂,在数控加工中易变形且难以控制,加工质量得不到切实保障。对目前的加工系统而言,数据加工过程可以分为三大步:一是加工前的工艺设计和离线零件编程,二是在加工过程中的在线加工和监控,三是加工后的检验处理。只有将三大步骤紧密结合协调统一好,才能确保工艺加工质量。但是,在线加工工艺系统会受到诸多因素的干扰,比如刀具变形、受热变形等,这些外在因素会严重影响质量。薄壁零件数控加工工艺在工业中的应用越来越广泛,保障加工工艺质量是当前急需关注和强调的问题。本文通过分析加工工艺的影响因素,提出改进装夹方案、修改切削参数、修正刀具路径、局部调整进给量等几种策略,来对加工路径和方式进行分析和优化,达到改进加工工艺质量的目的。
The rapid development of computer technology and simulation technology are pushing the thinwalled parts CNC machining process by the process of transformation of immature development of Engineering science. In this process, the processing technology of the thin wall parts CNC experience traditional research into scientific quantitative analysis ＂＂. Thin wall parts there is the problem of poor rigidity, structure is complex, in NC machining deformation and difficult to control, the processing quality can not be guaranteed. The processing system at present, the data processing process can he divided into three steps： one is the processing of process design and the offline part programming, two is the online processing and monitoring in machining process, three is processed after the inspection. Only three steps closely coordinated unification, to ensure the process quality. However, online processing system may be interfered by many factors such as tool, deformation, thermal deformation and so on, these external factors will seriously affect the quality of. Application and thin wall parts CNC machining process in industry more widely, guarantee the processing quality is the need to pay attention to the problem. In this paper, through the analysis of the factors influencing the machining process, put forward the improvement clamping scheme, modification of cutting parameters, tool path correction, partial adjustment of feed several strategies, to analyze and optimize the processing route and mode, to improve the machining quality objective.
