Description

  The present invention relates to a metal saw (circular saw), and in particular, a novel metal saw for cutting a curve, which cuts a carbon fiber reinforced plastic laminated plate, duralumin plate, other synthetic resin plate, metal thin plate, etc., which is an aircraft body, and its processing. The present invention relates to a method and a processing apparatus.

  In recent years, for example, there has been an increase in demands for low fuel consumption in order to cope with an increase in international logistics by aircraft and to improve the environment for the earth, and weight reduction and improvement in fuel consumption of aircraft have been attempted. As a concrete measure, since fiber reinforced plastic composite products such as CFRP (carbon fiber reinforced plastic) are lightweight and have high strength and rigidity, structural members such as aircraft (main wing, tail wing, fuselage) Etc.). Curve cutting of the structural members of the aircraft is performed by a special curve cutting machine, a hand tool (a cutting tool using a circular saw), or a curved blade cutter.

  As an example of the dedicated curve cutting machine, a thin plate cutting machine is provided. The configuration is such that the holding member can be moved relative to the work table in any three-dimensional direction, and a rotary blade having a V-shaped cutting edge made of a super hard material is attached to the tip of the holding member. To do. The thin blade on the work table is cut by appropriately moving the rotary blade in the X-axis and Y-axis directions while rotating and driving the rotary blade at a high speed while moving the holding member down to a predetermined height. As a result, the small-diameter disk-shaped rotary blade is rotated relative to the plate material and moved in the X and Y axis directions to cut the plate material. For example, as in a conventional laser processing machine, the plate material is appropriately selected. The product of the shape can be easily cut out. (For example, refer to Patent Document 1).

  The above-mentioned curved blade cutter is an improvement of a flat circular cutter (including a circular saw), and has a structure in which a mounting hole for a rotating shaft is provided at the center of a circular shape, and a cutting blade member or a saw tooth is provided on the outer periphery of the circular shape. It is a metal dish-shaped circular cutter equipped with a member, and the periphery of this outer periphery is formed of a conical dish bowl member, and several cut grooves are formed on the entire conical surface of the dish bowl member. The conical radial members are arranged at equal intervals, and the cutting blade members or sawtooth members provided on the outer peripheral edge of the counter ridge member are also arranged at equal intervals across the cut groove, and each has a circumferential arrangement in the conical shape. In addition, both the inner and outer side surfaces of the cone shape of the transplant blade member or the sawtooth member form the conical arc-shaped cutting blade. Thereby, first, the cutting blade to be rotated and cut can always maintain a suspended state with respect to the surface of the flat work material, and at the same time, during the rotary cutting and cutting with respect to the cutting edge width of the cutting and cutting blade, A constant clearance can be constantly maintained on both sides of the rotary blade. Next, as a rotational cutting curved blade that reasonably matches a large and small circular arc of a flat work material required for cutting, an unreasonable load such as galling and stagnation is not applied during the rotational cutting. (For example, refer to Patent Document 2).
