Background
Currently, at the site of manufacturing, high efficiency and high precision machining of complicated shaped parts are required due to weight reduction of parts, reduction of the number of parts and complication of part shapes. In order to deal with this, the introduction of multi-axis machine tools (multi-task machine) is proceeding.
However, highly skilled skill is required for operation, problems of interference prevention and process design are difficult, intelligence and optimum processing are difficult and they are still in the development stage(Figure 1).
Therefore, in this theme, we are working to realize automatic interference avoidance, sensorless intelligence, optimization control technology of multi-axis machine tool for the first time in the world.
Goals
- Technical goal
FY 2014-2015: Development of element technology (interference collision avoidance, process design, intelligence, optimal control)
FY 2016 - 2017: Development and verification of a simple high precision and high efficiency processing system
- Outcome(Ripple Effect)
- Everyone can easily use multi-task machine. Level up of machining technology
Expansion of potential users of multi-task machines
Complex shapes that could not be processed conventionally can be made, and delight design can be realized
