This document summarizes a seminar report on virtual manufacturing. It includes an outline covering topics like what virtual manufacturing is, its characteristics and classification, the virtual reality and other technologies used, as well as benefits, drawbacks and applications. Virtual manufacturing uses simulation, virtual reality and information technologies to generate digital information about the structure and behavior of manufacturing systems. It allows for interactive simulation of processes like virtual prototyping and assembly.

The power of immersive virtual manufacturingHemanth kumar
Virtual manufacturing (VM) is the use of computers to model, simulate and optimize the critical operations and entities in a factory plant. Virtual manufacturing started as a way to design and test machine tools but has since expanded to encompass production processes and the products themselves. The main technologies used in VM include computer-aided design (CAD), 3D modeling and simulation software, product lifecycle management (PLM), virtual reality, high-speed networking and rapid prototyping.
Virtual manufacturing provides an organization with the ability to analyze the manufacturability of a part or product as well as evaluate and validate production processes and machinery and train managers, operators and technicians on production systems. There are three main subcategories of VM:

Development Prototype Design of Virtual Assembly Application-Based Leap MotionIJAEMSJORNAL
Innovation in design engineering practice is very important in the world of manufacturing in the increasingly competitive global market. Prototyping and evaluation measures are inseparable from the design process in the manufacture of a product. And made one of many physical prototypes require very expensive and time consuming, so the technology of Virtual Reality (VR) is needed, so the industry can quickly and precisely in the decision. VR technology combines a human being with a computer environment visually, touch and hearing, so that the user as if into the virtual world. The goal is that users with hand movements can interact with what is displayed on the computer screen or the user can interact with the environment is unreal to be added into the real world. VR is required for simulations that require a lot of interaction such as prototype assembly methods, or better known as the Virtual Assembly. Virtual Assembly concept which was developed as the ability to assemble a real representation of the physical model, the 3D models in CAD software by simulating the natural movement of the human hand. Leap Motion (accuracy of 0.01mm) was used to replace Microsoft's Kinect (accuracy of 1.5cm) and Motion Glove with flex sensors (accuracy of 1°) in several previous research. Leap mot ion controller is a device that captures every movement of the hand to then be processed and integrated with 3D models in CAD software. And simulation of assembly process virtually in CA D software with hand gestures detected by the leap mot ion, assembly parts can be driven either in translation or rotation, zooming and adding the assembly constraint. It also can perform mouse functions (such as left-click, middle-click, right-click and move the mouse cursor position) to a virtual assembly process simulation on CAD software.
Additive manufacturing (AM) or additive layer manufacturing (ALM) is the industrial production name for 3D printing, a computer controlled process that creates three dimensional objects by depositing materials, usually in layers.
AM is a rapidly growing field that is having an impact on multiple industries by simplifying the process to go from a 3D model to a finished product.
In contrast to conventional manufacturing processes, AM fabricates objects by adding materials as required which eliminates the necessity of subtracting materials (by means of machining, milling, carving, etc.) to obtain desired shapes.
AM can advantageously fabricate complex geometries with no part-specific tooling and much less waste material.
In the construction sector, architectural models have been created with AM methods for more than a decade.
Recent years have seen a vast increase in research on printing methods for building components.
AM allows building companies to produce geometrically complex structures, to vary materials within a component according to its functions, and to automate the construction process starting from a digital model.
The technology can bring significant benefits to the construction industry in terms of increased customization, reduced construction time, reduced manpower, and construction cost.

B Kindilien-The Digital Age of ManufacturingjgIpotiwon
Making modeling and simulation make sense to manufacturers: You’ve seen the video games young people play: Computer-generated environments with rich three dimensional (3D) visuals and hardware with force feedback, touch-sensitive game controllers, and head-mounted displays that give the gamer a nearly (virtual) exact contextual representation of the world (reality) we live in. Think these tools are child’s play? The National Aerospace Leadership Initiative’s (NALI) modeling and simulation team wants you to think again.
“Virtual machining” is a modelling process that realistically simulates the setting up and running of an actual machining operation. First, the user specifies the stock from which the part will be cut, either by entering dimensions into the software or importing a CAD model. Then, after selecting the cutting tools, the NC program (either G-code data or native CAM output) automatically simulates the motion of the tool removing material from the stock. The programmer can watch the material removal process and see details of how each cut changes the shape of the part. This eliminates having to try to imagine how cuts from the current operation will affect subsequent operations.

13. VIRTUAL REALITY TECHNOLOGY
Virtual Reality is technology for presentation of complicated
information, manipulations and interactions of person with
them by computer.
Virtual Reality is a computer-generated interactive three-
dimensional environment to simulate reality.
Virtual reality with ability to show data 3D and attach sounds
and touch information increases extraordinarily data
comprehensibility.
Virtual reality has entered into the public awareness as medial
toy with equipment „helmet-glove“, which was preferentially
determined for wide public and the price of this system had also
to correspond to this fact, so price could not be very high.
