Virtual manufacturing is fast becoming an affordable technology with wide-ranging applications in modern manufacturing. Its advantages over existing technology are primarily that users can visualize, feel involvement and interact with virtual representations of real world activities in real time. In this paper, a virtual cutting system is built which can simulate turning process, estimate tool wear and cutting force using artificial neural network etc. Using the simulated machining environment in virtual reality (VR), the user can practise and preview the operations for possible problems that might occur during implementation. This approach enables designers to evaluate and design feasible machining processes in a consistent manner as early as possible during the development process.

“…But the biggest advantage is to realize fast collision detection by using the bounding box for collision detection. According to this specific system, we adopt the axial bounding box method in order to improve the efficiency of collision detection [8]. For example, there is a very heavy workload to check the intersections between all the sides and faces of the two complicated models which is directly used in the collision detection.…”

According to the single release form of product information on the network in machine manufacturing enterprises and the high price of the conventional NC simulation software, a machining simulation system based on Web is developed in this paper. Making use of the superiority of Java and JavaScript on Web and the interaction of VRML technology, 3D browsing, virtual assembly and machining simulation are realized on the network. Based on the authenticity and real-time of virtual reality, a network distributed virtual simulation system is designed. This method of NC machining simulation is not dependent on the expensive CAD/CAM software, and for the size of the system files is small, it can be transferred on the network conveniently. Using the browser with the plug as the client, the system has free installation, authenticity, interaction, low cost, portability, low requirements for the client, etc.

“…A new application framework "enhanced virtual machining" was developed by Lin and Shen [6] to quantitatively predict the part geometry errors. Wang et al [7] proposed an illumination model to build a realistic turning machining scene such as chip formation during machining operation. Haptic rendering in milling and grinding operations were also reported in [8] and [9] respectively.…”

A prototype system called haptic virtual turning operation system (HVTOS) is presented in this paper. The HVTOS system has three kinds of interactive tools for cutting, browsing and grinding. In cutting operation, a NURBS deformation algorithm is proposed for workpiece modeling which is expected to accelerate haptic and graphical rendering. For grinding operation, a simple NURBS trimming technique is used. In using the HVTOS system, a user can manipulate a virtual tool to cut or polish a virtual workpiece with force feedback as if he/she is working on a real turning machine. The force feedback varies with different simulation parameters such as cutting depth and material properties (e.g. hardness, surface friction and damping coefficients), which can be set by the user before operation. During operation, tool positions and their corresponding forces are recorded in order to provide data for analyzing the performance of tool paths. Vibration, friction and viscous effects felt by a user can improve the simulation fidelity. The proposed system provides an intuitive way not only for the modeling of three dimensional revolved objects but also for the training of lathe machining and grinding operations. Several models created by this system are given to illustrate the easiness and effectiveness of the HVTOS.
