| Outline of Final Research Achievements |
This research has developed a compact triaxle NC milling machine with high precision steel cutting, the volume of which is about half the size of general ones. By sharing the base with plural machine tools, the proposed one has miniaturized its structure. The reduction in size results in the reduction in rigidity and induces the deformation of the machine tool. In order to suppress the machining errors, a method to correct the tool path by predicting the deformation of the machine tool has been proposed. The proposed method can reduce the machining error to several μm in the cutting of SS400. Additionally, a vibration absorption method with a piezoelectric element was proposed. The method applies intermittent impact to the structure in a direction orthogonal to the vibration. By hammering test with a cantilever, we confirmed the damping capacity increases. As the method needs no complex control, it can be expected to suppress the chatter vibration of machine tools
