Abstract (en)
[origin: WO9417683A1] Cutting is performed by automatically controlling relative movement between a cutting blade and a material along a desired cutting line according to set tangential speed and acceleration values for each line. On reaching an angle between a first cutting line path and a second path, the blade is rotated as it moves through the material so that it switches automatically from a first direction tangential to the first path, to a second direction tangential to the second path. Blade rotation takes place at a predetermined average rotation speed over a rotational path consisting of a predetermined portion of the first path and/or the second path which ends or begins at the apex of the angle or includes said apex. The average speed of the blade moving along the rotational path is correlated to the average blade rotation speed and the angle value, whereas the cutting blade moves along the first path and/or the second path, when outside the rotational path, at a set tangential cutting acceleration and speed determined for said path(s).
