Development of a Learning-Training Simulator with Virtual Functions Lathe Operations

本研究旨在开发一个具有虚拟功能的车床操作学习训练模拟器。首先，一个原型模拟器模拟一个实际的车床已经产生。该模拟器提供了一个综合的操作感觉协调视觉，听觉，力和触觉实时操作员。这使得操作员在操作模拟器时感觉好像他或她在操作实际车床。该模拟器已被上越教育大学的金属切削技术教育科目采用，并在新泻县向工业高中机械系教师讲授的技术讲座课程中进行了演示。考虑到真正操作过模拟器的用户的意见，对模拟器的硬件和软件进行了根本性的改造，以进一步提高训练性能。最终模拟器的主要功能和特点是：（1）T ...更多信息 以实际车床的纵向、横向和尾架主轴方向进给驱动系统为基础，进行了硬件设计。实现了直车、钻削、锥车、切断、端面五种切削加工的单一模拟功能，以及模拟机械零件复合加工的高级零件加工功能。(2)In切削的模拟操作，该模拟器可以为操作者提供足够真实的感觉来操作车床的进给手柄。同时，扬声器播放工作的声音效果，主轴和工件的旋转以及字节进给实时响应于与操作者的动作相关的进给手柄的旋转而动画地显示在屏幕上。(3)In为了有效地训练初学者掌握基本技能和安全操作方式，在模拟器中开发并实现了许多有效的安全训练和帮助功能，如字节提示位置的调整、设定操作顺序的检查、危险动作的警告等。少

This research aims at developing a learning-training simulator with virtual functions for lathe operations. Firstly, a prototype simulator modeling a practical lathe has been produced. The simulator provides a synthetic operating sense harmonizing sight, hearing, force and touch to the operator in real-time. This makes the operator feel as if he or she were operating an actual lathe while operating the simulator. The simulator has been adopted for use in a technical education subject for metal cutting at Joetsu University of Education and demonstrated in a technical lecture course, taught in Niigata Prefecture, to teachers working in mechanical departments of industrial high schools. Taking into consideration the opinions from the users who had really operated the simulator, a radical remodeling for both hardware and software of the simulator has been undertaken in order to further improve the training performance. The main functions and characteristics of the final simulator are :(1)T … More he hardware is designed based on the feed driving system of an actual lathe in the longitudinal, transverse and trailstock spindle directions. Five single imitation functions of cutting operations, straight turning, drilling, taper turning, cutting off and facing, are realized together with an advanced function of part machining, which imitates the compound process of machining a mechanical part.(2)In an imitation operation of cutting, the simulator can provide the operator with a sufficiently real feeling for operating the feed handles of a lathe. At the same time, the sound effect of working is played by the speaker and the revolutions of spindle and work, and the byte feeding are animatedly displayed on the screen in real-time responding to the feed handle rotation related to the operator's action.(3)In order to train efficiently a beginner to acquire basic skills and safety operating manners, many of effective safety training and help functions, for example, adjustment of byte tip position, check to set-up operation sequence, warnings for dangerous actions and so on, are developed and implemented in the simulator.
