Defining Digital Manufacturing
Digital manufacturing is an innovative approach to manufacturing that uses computer technologies to improve manufacturing operations. It is an integrated process that connects all aspects of production, from design to production and on to the servicing of the final products.
Digital manufacturing technologies link systems and processes across all areas of production to create an integrated approach to manufacturing. This approach allows companies to optimize the manufacturing process, reduce production costs, and increase production efficiency.
Digital manufacturing tools can connect and simplify processes across the production cycle to create a “digital thread” that integrates manufacturing operations to streamline and enhance design, production, servicing, and more. These tools are used to simulate and model processes so that they can be optimized before production begins.
One of the key benefits of digital manufacturing is that it allows companies to produce customized products on a large scale. For example, a company can use digital manufacturing to create a unique design for each customer without incurring the high costs associated with traditional manufacturing processes.
Another benefit of digital manufacturing is that it allows companies to reduce the amount of waste generated during the manufacturing process. By optimizing the manufacturing process, companies can reduce the amount of raw materials and energy needed to produce a product. This, in turn, reduces the environmental impact of manufacturing.
Overall, digital manufacturing is a powerful tool that can help companies reduce costs, increase production efficiency, and create customized products on a large scale. With the rise of computer systems in manufacturing plants, it has become necessary to model, simulate, and analyze manufacturing processes to optimize production. Digital manufacturing is the solution that companies are turning to in order to stay competitive in today’s fast-paced manufacturing environment.
History and Evolution of Digital Manufacturing
Digital manufacturing has been around since the 1970s, but it has evolved significantly over the years.
