Blade, in particular oscillating blade, to be used in a machine cutting method for cutting sandwich plates

Cutting machine blade (1) according to one of the preceding claims,

• characterized in that
• lips formed by the cutter back (18) and respective front and rear surfaces of the cutter leaf (17) are chamfered.

Cutting machine blade (1) according to one of the preceding claims,

• characterized in that
• the edge (16)—as seen in the extent from the cutter tip (19) in the direction of the holding section (15)—forms the first zone (12) before the intermediate zone (13) and the intermediate zone (13) before the second zone (11).

Cutting machine blade (1) according to one of the preceding claims,

• characterized in that
• the cutter (10) tapers in two stages in the shape of a wedge from the cutter leaf (17) to the edge (16), first surfaces (48) of the wedge, directly forming the edge (16) tapering less acutely than convergent second surfaces (49) of the wedge, extending between the first surfaces (48) and the cutter leaf (17), in particular with the first surfaces (48) forming an edge angle of between about 15° and 50°, and the second surfaces (49) converging with an angle which is between about 3° and 20° less than the edge angle.

Cutting machine blade (1) according to one of the preceding claims,

• characterized in that
• the cutting machine blade (1) is formed as an oscillating blade to be fitted in an oscillating cutting tool, and is intended for use in the scope of a defined stroke cutting mode, in which the cutting machine blade (1)—in addition to the guiding along the feed direction (52)—is moved by the cutting tool oscillating up and down in a stroke direction (51) essentially perpendicularly to the composite plate (20) to be cut, in particular with the stroke cutting mode having a stroke of between about 0.2 and about 12 millimeters, a stroke frequency of between about 50 and about 800 Hz, and a cutting speed in the feed direction (52) of between about 0.1 and about 4 meters per second,
• in particular with the stroke cutting mode having a stroke of between about one and about five millimeters, particularly between about two and about three millimeters, in particular about 2.5 millimeters, a stroke frequency of between about 100 and about 500 Hz, particularly between about 200 and about 300 Hz, in particular about 250 Hz, and a cutting speed in the feed direction (52) of between about 0.5 and about 2 meters per second, particularly between about 0.75 and about 1.5 meters per second, in particular about one meter per second.

Cutting machine blade (1) according to one of the preceding claims,

• characterized in that
• the cutter (10) with the edge (16) is formed in such a way that the first angle (41, 42) made with the feed direction (52) by the respective profiles of the edge (16) in the region of the first and second zones (12, 11) is between about 40° and about 65°, particularly between about 45° and about 60°, in particular about 52°.
