TL;DR

This paper proposes a virtual manufacturing framework integrating modeling, simulation, and optimization to enhance design and production processes across product development, process planning, and manufacturing systems. By leveraging CAD/CAM-like digital twins, it enables early detection of errors and performance optimization, significantly reducing time-to-manufacture and improving decision-making in automated environments.

ABSTRACT

The research area "Virtual Manufacturing" can be defined as an integrated manufacturing environment which can enhance one or several levels of decision and control in manufacturing process. Several domains can be addressed: Product and Process Design, Process and Production Planning, Machine Tool, Robot and Manufacturing System. As automation technologies such as CAD/CAM have substantially shortened the time required to design products, Virtual Manufacturing will have a similar effect on the manufacturing phase thanks to the modelling, simulation and optimisation of the product and the processes involved in its fabrication.

Motivation & Objective

• Address the growing need for faster, more accurate decision-making in manufacturing by reducing reliance on physical prototyping.
• Overcome limitations in traditional design and production workflows that delay time-to-market and increase costs.
• Integrate simulation and optimization across product, process, and system levels to improve manufacturing efficiency.
• Enable real-time virtual validation of manufacturing processes before physical implementation.
• Bridge the gap between design and production through a unified digital environment for process control and optimization.

Proposed method

• Develop a virtual manufacturing environment that integrates product and process modeling across design, planning, and production stages.
• Utilize simulation techniques to model machine tools, robots, and manufacturing systems in a digital twin framework.
• Apply optimization algorithms to evaluate and refine process parameters before physical execution.
• Leverage existing CAD/CAM technologies as a foundation for virtual process replication.
• Implement a feedback loop between virtual simulations and real-world manufacturing data to improve accuracy.
• Use standardized interfaces to ensure interoperability between design, simulation, and control systems.
