Abstract

"Virtual manufacturing (VM) is a virtual reality based engineering application that provides an environment to model and simulate an actual manufacturing system through effective use of computers. Virtual computer numerical control (VCNC), which falls under the realm of virtual manufacturing applications, involves the development of a computer based virtual environment for modeling and simulating the functionality of a machine tool and the material removal process. In this thesis, virtual modeling and simulation of Bridgeport Series I CNC R2E3 Milling Machine with BOSS 81 (Bridgeport Operating System Software) controller and Cincinnati Milacron Sabre 750 3-axes CNC Vertical Machining Center with Acramatic 2100E CNC open architecture controller are presented. The above-mentioned virtual machine tools, which were developed using Deneb’s Virtual NC version2.1 simulation software, provided the means for realization of the machining process on a computer, before the actual machining process is commenced on the real machine. Various CNC programs developed for machining various parts were simulated using the developed virtual CNC machines and virtual CNC controller. The virtual controller has the capability for detecting collisions between the different machine components as the CNC part program is being simulated. While running the simulation, the user can observe the changes in various parameters like feed rate, depth of cut, material removal rate, cycle time etc. Virtual machine tools that were developed will help in improving the quality of machined components, eliminating catastrophic program errors and optimizing the cutting path. As a future work, the developed virtual machine tools can be incorporated in a web-based virtual environment where the user can input his CNC programs through a graphical user interface for simulation"--page iv.
