摘　　要：基于激光制造的现代加工技术是工科学生的必修课程,由于受实验场地、实验设备、安全性等条件的限制而不能满足实验教学需求。为了构建以学生为中心、以能力培养为核心的实验教学平台,介绍了一种基于Unity3D开发的激光切割虚拟仿真实验教学系统。该系统采用图形用户界面和对话框驱动,能够模拟真实的激光切割加工过程,包括实验原理、部件认知、加工参数、激光制造过程、工艺参数对切缝宽度的影响、实验结果分析等内容,弥补了实验条件、实验成本、交互性、安全性等诸多不足,有助于提高学生的学习积极性、创新精神和实践能力。The modern processing technology which based on the laser processing is a compulsory course for mechanical undergraduates. Due to the limitations of experimental site, equipment and safety issues, the actual requirements cannot be satisfied during the process of experiment teaching. In order to build a student-centered and ability-centered experiment teaching system and platform, a set of virtual simulation experiment teaching system of laser cutting technology was developed by Unity3 D. Driven by graphical user interface and dialog box, the system can simulate the complete flow of real laser cutting experiments, including experimental principles, component cognition, processing parameters, laser manufacturing process, influence of technological parameters on slit width, experimental results analysis and other contents. The system can make up for the real experimental conditions, experimental costs, interaction, safety and other deficiencies which is helpful to improve students’ participation and enthusiasm, and cultivate students’ spirit of innovation and practical abilities.
