    Abstract: PROBLEM TO BE SOLVED: To provide a cutting method to reduce cutting force, improve machining accuracy, restrain chattering vibration, reduce wear of a tool, and also enable cutting of materials hard to machine. SOLUTION: The tool is made to elliptically vibrate in the plane (yx plane) which contains the cutting direction (x direction) and the feed direction (y direction). Or the tool is made to elliptically vibrate in the yq plane which is decided by rotation of the yx plane for Θ about the y-coordinate. Or the tool is made to elliptically vibrate in the hx plane which is decided by rotation of the yx plane for Φ around the x-coordinate.

    Abstract: PROBLEM TO BE SOLVED: To provide a mechanism to exactly decide the position of a table in a 'walking drive' device to transport the table by alternately supporting the table by repeating contact and isolation on the rear surface of the table in which driving parts of A and B groups repeat a 'transport' operation in the transport direction. SOLUTION: The position of the table is controlled by: providing many stepping stones regularly deployed with a pitch equal to or smaller than the stroke of elements for transport of the driving parts on the lower surface of the table with which the contact blocks of the driving parts are brought into contact; and driving the table while two or more driving parts maintain the contact with the stepping stones.

    Abstract: PROBLEM TO BE SOLVED: To reduce cutting resistance, and set component force in a cutting edge tip direction to be apparently zero, to restrict abrasion of a cutting edge tip of a tool and deformation and decomposition of subject material to be cut, and to improve work precision. SOLUTION: In this vibration-cutting method, the tool 1 is relatively vibrated to the subject material 2 while cutting it. A cutting edge 3 of the tool 1 is relatively reciprocated to the subject material 2 in the cutting edge tip direction 6 of the tool 1 for cutting it in both directions of reciprocation. After cutting, the cutting edge 3 is separated from the subject material 2 (cutting point) at points 16 and 17 where vibration speed of the cutting edge 3 at least in the cutting edge tip direction 6 becomes zero. This vibration-cutting device is provided with a first and a second actuators to vibrate the tool 1 in the cutting edge tip direction 6 and a cutting direction 7, and a control part to control action of the first and the second actuators to conduct vibration-cutting in accordance with locus.
