Development of A Hybrid Multi-tasking Machine Tool: Integration of Additive Manufacturing Technology with CNC Machining

Abstract Reduction in manufacturing cost and total in-process time is critical for industries in developed countries in order to maintain competitive advantage. At the same time, high added value manufacturing is also required. If not addressed, it will become increasingly difficult for the manufacturing industries in high-wage countries who are at a competitive disadvantage to survive in the future. In order to meet these requirements by creating a new possibility for machine tools, a Hybrid Multi-tasking machine tool has been developed by equipping Laser Metal Deposition functionality in addition to existing integrated turning and milling capabilities. The concept of a Hybrid Multi-tasking platform enables a further evolution of Done-in-One processes enabling building near-net shape components to be produced by additive manufacturing and then quickly generating the net shape through high-precision finish machining operations. It is particularly well suited to small-lot production of difficult-to-cut materials, such as aerospace alloys, high-hardness materials used in the energy sector, production tools and components and high-precision, specialty alloy designs common in medical device manufacturing. This paper introduces the features of the Mazak Hybrid Multi-tasking machine tool with application examples and demonstrates possibilities and tasks for the next generation manufacturing.
