基于虚拟仿真的线切割实训课程设计

Design of WEDM Training Course Based on Virtual Simulation

摘要: 电火花线切割加工具有加工精度高、加工质量好、工件表面无切削应力的优点，能够完成贯通结构的小拐角、窄缝、深径比孔。教学研究中综合了手工趣味编程、数控编程、虚拟仿真，构建了三位一体的教学模式，层层推进、虚实结合，夯实学生实践基础。课程内容安排集工程实践和工程实际于一体，旨在培养机械类学生在面对复杂工程类问题时发现、分析、解决问题的能力，解决传统教学模式场地、学时、设备等受限，学生实践能力培养层次低的问题。

Abstract: WEDM has the advantages of high machining precision, good machining quality and no cutting stress on the surface of the workpiece. It can complete the small corner, narrow slot and depth diameter ratio hole of through structure. In the teaching and research, we have integrated the interesting manual programming, numerical control programming and virtual simulation, and constructed a trinity teaching mode, which can push forward layer by layer, combine the virtual and real, and consolidate the students’ practical foundation. The course content arrangement integrates engineering practice and engineering practice, aiming to cultivate the ability of mechanical students to discover, analyze and solve problems in the face of complex engineering problems, and solve the problems of traditional teaching mode, such as limited space, class hours, equipment, and so on, and the cultivation level of students’ practical ability is low.
