“New advances in computerized modeling, visualization and simulation are making virtual manufacturing (VM) a viable alternative to conventional manufacturing resources. VM relies on the technology of modeling and simulation to simulate the manufacturing process in a virtual environment. This thesis presents the virtual modeling and simulation of Bridgeport Series I CNC R2E3 Milling Machine with BOSS 81 (Bridgeport Operating System Software version 8, inch unit) controller and virtual modeling and simulation of Okuma LB 15 CNC Lathe with OSP5000L control system using Deneb’s Virtual NC simulation software. The virtual components of Bridgeport CNC Milling Machine and Okuma LB 15 CNC Lathe were successfully modeled and assembled to create the virtual machines. Virtual CNC controllers were developed for both virtual CNC mill and CNC Lathe, which have the capability of reproducing the functionality of the actual CNC controllers. Various CNC programs written for machining various parts were successfully simulated on the virtual machines. Both the virtual CNC controllers have the capability to detect collision between all machine components as the CNC part program is being simulated and allow the user to monitor various machining parameters like the depth of cut, feed-rate, cycle time etc. The developed virtual CNC machines can simulate and reproduce the actual machine tools as well as the entire machining process, thus eliminating dry runs and catastrophic program errors, improving the quality of machined components and optimizing the cutter path. Ongoing research is aimed at developing a web-based virtual manufacturing environment where the users will be able to enter the CNC program through a graphical user interface and use the developed virtual machines to simulate the CNC programs”--Abstract, page iv.
