And also, the machining accuracy of the thin wall by the non rotational tool is compared with that by an end mill. The main results are as follows. (1) FEM models for the tool and workpiece are made and the machining accuracy is predicted based on the deflection analysis using FEM due to the cutting force. (2) The tendency of the shape of machined surface is almost coincident to that of the predicted shape, then the propriety of the method of analysis is verified. (3) The shape error by the non rotational tool is not influenced on the radius of the curvature of the workpiece, the cutting speed and the type of machining side, and the tool realized about 3 \u03bcm of the shape error as the target. (4) The dimensional error is 3-9 \u03bcm larger than that by the predicted value. But, it is considered that about 2 \u03bcm of the spring back error caused by the radius of the tool edge is included in the above error. (5) The roughness Ry of the machined surface by the non rotational tool is smaller than 3 \u03bcm as the target, then it is possible to use the tool for machining the thin wall such as the scroll shape.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "41021",
