Emulation Training System For CNC Lathes Based On VR

The CNC lathes are the modem manufacturing means. The equipment is expensive and its operation is complicated. So it has brought high difficulties to manipulator's training. The emulation training system of CNC lathes based on VR are designed for solving these problems.With the developing of CNC emulation and VR technology, the combination has bright future. In this thesis, the whole system design scheme and the function of each module based on VR are proposed.The establishment of VR environment is chiefly depended on three dimensions of scene as well as each object's true operation. Model's export means using 3DS MAX is introduced particularly. It also expounds how to make use of 3D Lingo language in Director's multi-medium software to drive 3D model in VR environment. Meanwhile, based on the three dimensions grid method, it proposed the solving way of producing reai-time 3D workpiece module.The developers are continuously concerned about protection for the intellectual property rights. In the 5th part of the thesis, it introduces the basic principle of RSA enciphered algorithm detailedly. It also put forward the enciphered science basis which using the serial number of hard disk, the way of procuring the serial number of hard disk, the realization of registered machine and decrypting procedure etc.As training system, the most central thing is to have a convenience prompt help function. The manipulator can get help in time. So Microsoft Agent technology is emphasized and the settlement scheme of system help is proposed.Instead of the development pattern of traditional VR technology based on compiles language, this article adopts 3DS MAX software to create the CNC lathes model, Photoshop to complete the interface, Flash to make the software controlling plane board. It also adopts the Shockwave3D technology and 3D Lingo language of Director to create 3D drive engine and to export 3D workpiece model real time. It realizes the emulation training system of CNC lathes based on VR. All of these open up high efficiency way to realize VR.
