基于VERICUT的数控镗铣加工仿真系统开发

摘要进入21世纪，越来越多的人开始重视虚拟加工技术，虚拟加工技术也因其具有实际加工所无法替代的优势而被人们所接受。为减少材料消耗以及提高加工效率，机械加工企业在对加工程序进行验证性试验，需要对程序进行适当性的优化处理。这就需要在虚拟加工环境下进行加工以得到最终加工结果。VERICUT作为仿真软件中的佼佼者越来越受到各大企业的重视。51996

本文通过使用VERICUT仿真软件，建立虚拟加工环境，从而对实际需要加工的零件进行虚拟加工，同时利用软件自身所带的优化模块对加工程序进行优化。首先，本文将介绍数控仿真加工技术以及国内外的发展情况，以便更好的了解虚拟加工仿真技术，其次，对VERICUT数控仿真软件以及其加工环境的创建过程进行相应的介绍。然后，介绍详细的加工环境设计过程，以实际机床为模型在VERICUT中创建机床，并完成相应的控制系统定义（包含修改相应的文字地址以及定义G代码变量），定制相应的数控子程序（换刀程序）。最后，在加工实例中，对加工轨迹以及刀具参数进行适当优化，从而对数控程序进行修改，以达到改善数控加工程序的目的。

Abstract

In the 21st century, more and more people are paying attention to virtual machining，Virtual processing technology has also been accepted by the people because of its practical advantages of processing can not be replaced. To reduce the material consumption and improve the processing efficiency, Machinery processing enterprises confirmatory test procedures for processing ，They need to program optimization appropriateness. This requires us to be processed to obtain the final processing results in a virtual processing environment. Today, there are many kinds of CNC machining simulation software, VERICUT taken seriously as a leader in simulation software.

This article create a virtual machining environment by using VERICUT simulation software, Optimize the machining process using software brought their own optimization module. First, This article will introduce CNC machining technology and the development of simulation At home and abroad, In order to understand the virtual machining simulation technology Better;Secondly, Introduce VERICUT CNC simulation software as well as the process of creating its processing environment; Then, Introduce processing environment design process detailiy,Create tool in VERICUT, Actual machine as a template, And define the corresponding control system,(Modify the corresponding text addresses variables and defined G code), Custom the appropriate numerical subroutine(ATC procedures). Finally, Appropriate optimization for machining path and tool parameters In the process instance, Modify the NC program,to achieve the purpose of improving the NC program.

Keywords: CNC machining; Virtual Machine; simulation process; tool path simulation; subroutine.
