Abstract: Processes of part manufacturing are modeled by mathematical concepts and simulated in virtual environments to be analyzed and modified. Thus, optimization methods can be applied to the simulated manufacturing process in virtual environments in order to improve efficiency of part production. Also, errors of simulated manufacturing processes in virtual environments can be predicted and analyzed in order to increase accuracy of produced parts. Moreover, more added value in part production can be achieved by developing manufacturing processes in virtual environments. As a result, an advanced production system can be presented by applying digital environments to manufacturing processes.

Keywords: Virtual manufacturing, Production optimization, Efficiency of part production, Accuracy of produced part

1. Introduction

Virtual manufacturing systems are applying computers and different types of software in manufacturing and production in order to simulate and model errors of real environment in virtual reality systems. The objective of simulating manufacturing technologies in virtual reality systems is to design a completely digital factory. The part is modeled and produced in a computer simulation environment with predicted errors in order to achieve the best accuracy in the produced part by choosing optimized process parameters. Virtual simulation provides a strong tool for producing and analyzing parts in digital environments in order to decrease cost and time of accurate production. The main objective is to understand and emulate the behavior and error effects of a particular manufacturing system on a computer environment. As a result, a reduction of testing and experiments on the shop floor production can be achieved.

2. Virtual analysis and modification of manufacturing processes

To analyze and modify manufacturing process in virtual environments, mathematical modeling can be used. Effects and behavior of the system are simulated by mathematical concepts in order to be analyzed and modified. So, different parameters of the process can be analyzed in order to be optimized. Thus, efficiency of part production can be increased by applying optimization methods to the simulated manufacturing process in virtual environments.

Modification can also be presented to the simulated system in virtual environments by analyzing and decreasing errors of manufacturing process. Therefore, accuracy of produced parts can be increased in order to improve efficiency of part production.

Machine tools Elements as well as production processes can also be simulated, analyzed and modified by using virtual manufacturing systems. So, stress, strain as well as deformation of machine tool elements can be analyzed in order to increase accuracy of part production.

In the CAPP application, the most suitable methods of part production can be selected by applying process planning methodologies to the simulated manufacturing processes in the virtual environments.

In order to provide the error effects analysis in virtual environments, the parts can be analyzed using the Finite Element Method (FEM). Moreover, residual stresses in machining operations can be analyzed and decreased by using virtual machining systems to increase safety level in produced parts.

Modified version of machining strategies can be obtained by analyzing cutting tool paths in machining operations of free form surfaces using 5-axis CNC machine tools.

IT-related problems in different production processes can be developed to new technologies, processes and methods by using virtual manufacturing systems. As a result, knowledge as well as capabilities of different virtual manufacturing systems can be shared in the web to increase efficiency of part production.
