Abstract: The device comprises a cutting head (2) freely pivotable within a solid angle range, and a positioning arrangement (3) by which the alignment of the processing direction of the cutting head is adjustable within the solid angle range. The cutting head is pivotably fixed. The pivoting is carried out around two axes running transverse or crooked to each other and the positioning arrangement comprises two positioning drives (6, 7) actuated independently from one another that are guidable along a linear axis (8, 9) and grip to the cutting head for pivoting the cutting head. The device comprises a cutting head (2) freely pivotable within a solid angle range, and a positioning arrangement (3) by which the alignment of the processing direction of the cutting head is adjustable within the solid angle range. The cutting head is pivotably fixed. The pivoting is carried out around two axes running transverse or crooked to each other and the positioning arrangement comprises two positioning drives (6, 7) actuated independently from one another that are guidable along a linear axis (8, 9) and grip to the cutting head for pivoting the cutting head, which is fixed in a gimbal actuator. The linear axes pass straight and/or the linear axes of the positioning drive are directed parallel to each other and/or transverse to each other and/or are arranged in a common plain. The plain is horizontally aligned in functional position of the cutting device. The linear axes are enclosed in functional position of the cutting device with a horizontal plain of respective angle and/or the linear axes are vertically directed in functional position of the cutting device. The linear axes are aligned in an acute angle or parallel to the processing direction of the cutting head in its middle position regarding to the pivoting movement and/or the linear axes are aligned in the acute angle or parallel to the middle axis of the solid angle range. The cutting head is fixed in a fork-shaped reception, which stands against the plain described through the linear axes in a right angle. Each positioning drive comprises sleds (11, 12) guidable along the linear axes and/or each sled is connected over a frame with the cutting head. The positioning device comprises an electric drive and the cutting head comprises means for plasma cutting, laser cutting, water-beam cutting and/or mechanical cutting. A control unit is formed for calculating an adjusted position of the positioning drive for a given angle alignment of the cutting head within the solid angle range and/or the opening angle of the solid angle range is 90[deg] and/or the cutting head is arranged in resting position in the middle axis of the opening angle. The pivoting of the cutting head is carried out around a first axis of the suspension of the cutting head through a counter-process of the positioning drive and/or the pivoting of the cutting head around the second axis of the suspension of the cutting head is carried out through the counter-process of the positioning drive. The suspension of the cutting head is tightly connected with a reinforcement of the positioning arrangement and/or guidable regarding to the reception for the workpiece, within an imaginary plain. An independent claim is included for a method for activation of a cutting device.
