Advanced digital manufacturing

Changes in international markets require that, in order to maintain their competitiveness, companies engaged in the manufacturing industry reduce their time to market and implement their ramp-up phases more efficiently. This becomes particularly emphasised in case of companies manufacturing valuable, customised B2B products. Specialisation and such products have been cornerstones of Finnish industry and exports for decades. Demanding digital manufacturing is an answer to these challenges, securing the success of Finnish manufacturers also in the future.

The use of computational modelling and simulation software is already commonplace in the manufacturing industry. However, problems often arise from the poor compatibility of such software programs, due to the use of systems from various suppliers. This is a very common problem in partnerships, where the software of the company and its customers and subcontractors are not directly compatible. The SMACC strategy for demanding digital manufacturing is to create a new concept, where the product’s digital model can be used effectively throughout the value chain of the product.

As regards demanding digital manufacturing, SMACC helps Finnish enterprises take advantage of the digital model as a means to improve their competitiveness. The more comprehensive application of simulations made using the model in the product development process, beginning with the preliminary planning and design phases, brings forward the launch of the iterative design process and making of the necessary changes in the design before the physical prototypes are made. The feedback loop from the data relating to the manufactured product enables updating of the digital twin in the course of the process. Deviations between the digital twin and the tolerated product show the need for changes in production parameters, such as machining parameters. The automatic feedback lays foundations for high quality and cost-efficient quality control; shortens lead times; improves the rates of utilisation of machinery; and enables the use of such tools as universal 4-axis and 5-axis machining tools and standard tools in demanding machining tasks as well.
