Ltd., Pune, India Abstract This paper attempts to unfold the possible areas and functions in an organization where Digital Manufacturing could have considerable effect on the overall efficacy of the sub-system and the system as a whole. With the introduction of Digital Manufacturing over the conventional setup, the Process Design, Workflow, Plant Layout, Resource Management and all other such functions are radically influenced and need to be reviewed in the light of the changed perspective for achieving production goals. The role of Information Technology and Communications or Network Engineering in the IT domain, form a backbone for this system. At a micro-level, the blending or the integration of the Mechanical Engineering aspects in the manufacturing setup with its counterparts in the Electronics and Communications domain is crucial to exploit the technology in realizing organizational objectives. The scope and the possible applications of Digital Manufacturing in Automotive Industry have been discussed in this treatise. Key words: Digital Manufacturing, Robotics, Assembly Simulation, Ergonomics, Process Design, Resource Utilization Fig. 1: Digital Manufacturing complete Scope I. INTRODUCTION Digital manufacturing has been considered, over the last decade, as a highly promising set of technologies for reducing product development times and cost as well as for addressing the need for customization, increased product quality, and faster response to the market. The evolution of information technology systems in manufacturing, outlining their characteristics and the challenges to be addressed in the future needs to be dealt with. Together with the digital manufacturing and factory concepts, the technologies considered here include computer-aided design, engineering, process planning and manufacturing, product data and lifecycle management, simulation and virtual reality, automation, process control, shop floor scheduling, decision support, decision making, manufacturing resource planning, enterprise resource planning, logistics, supply chain management, and e-commerce systems.

Centerline (Windsor) Limited Fig. 19: Human Reachability study C. Metris Based Adaptive Robot Control Brings Aerospace Tolerances to Automotive Robots Metris has taken part in a major Airbus research project that results in greater level of automated drilling and riveting within the aerospace giant. Since industrial robots do not meet Airbus process specifications, Airbus, Metris, KUKA and DELMIA partnered to develop a new aerospace grade robotic platform. This patent-applied-for solution establishes a dynamic on-line link between a KUKA robot and a Metris K-series Optical CMM based metrology solution.

B. Airplane Maintenance Simulation Analysis - Safer and More Efficient Manufacturing Processes A leading aircraft manufacturer turned to Applied Manufacturing Technologies, Inc. (AMT) to use their simulation and process consulting expertise to identify issues and recommend solutions for service and maintenance operations on the manufacturer s airplanes. They asked AMT to perform service analyses on four specific maintenance operations with special consideration to ergonomic impact. AMT chose to use DELMIA V5 Software to do the analysis. DELMIA, a subsidiary of Dassault Systemes, offers a comprehensive suite of digital manufacturing software that streamlines manufacturing processes to bring products to market faster as well as lowering manufacturing costs and encouraging innovation.

6 Fig. 22: Robot Programming and simulation In this project both ABB s Robot Studio and Dassault s DELMIA V5 were successfully used, providing a simple method of creating robot programs and proving them off-line. Fig. 23: Relealistic Robot Programming and simulation using DELMIA V5 E. Holland Project: Digital Reconstruction of Naval History Digital Simulation: - Kinematics models were developed for mechanisms such as the access hatch and latching mechanism, inner and outer torpedo tube doors, gasoline engine, pumps, and electric motor/ generator. In each case, the kinematics mechanism was used to validate the design and to provide insight into the operation of the submarine. The combination of Part Design, Assembly design and Kinematics produced a complete physical model, but how did it really work? What were the steps involved in getting underway, diving the boat, firing a torpedo, and conducting routine maintenance? F. DELMIA s Digital Process for Manufacturing (DPM) provided many of the tools needed to answer these questions. DPM was used to simulate the operation of all equipment onboard the USS Holland, including submerging and torpedo launching and reloading. Fig. 24: DELMIA V5 in Submarine and Torpedo launching Mechanical simulations are great, but in a submarine such as the USS Holland where space is limited, it was important to determine how long it would take for a man to get into position to close a valve, pull a lever or flip a switch. DELMIA s Human Task Simulation was used to explore these areas.
