Abstract:
When cutting the flat products (3) a set of the desired shapes and dimension of the products (3) is defined. Firstly at least one surface of the material (1) is scanned; scanning sets the boundaries of the available surface of the material (1). Optical scanning can be supplied by radiological scanning, preferably by means of a CT scanner (8). Defects (2) are identified in the scanned image and a position is assigned to them. A weight coefficient is assigned to each element from a set of the desired shapes and dimensions of the products (3). A cutting plan (4) is created; this plan (4) defines the boundaries of individual flat products (3), whereby the places with the identified defects (2) of the material (1). Optimalization of the distribution of the desired products (3) is realized with the goal of achieving the highest sum of the number of the products (3) multiplied by the weight coefficient of a given product (3) without the need to cut all the elements from a set of the desired products (3). Subsequently a cutting machine (6) is used to cut the products (3); this machine (6) cuts the material (1) without any limitation with regard to the mutual position of the cut lines of the neighboring products (3).
Abstract:
The invention relates to a method of cutting a sheet-like piece into one or several smaller pieces by using camera means and a controllable cutting apparatus, the directions and values of the coordinate systems of which are calibrated to correspond to each other. In the method following measures are taken: the piece to be cut is placed on a cutting surface located within the recording area of the camera means, the piece is photographed by the camera means and on the basis thereof the outlines of the piece are determined and the information on the outlines of the piece is input into the positioning system, where the cutting paths are established and input into the control system of the cutting device, which determines necessary parameters for the cutting and on the basis of these, controls the cutting of the piece into parts according to given instructions.

Abstract:
The invention relates to methods and systems for preparing a cutting path for machine cutting of a plurality of parts from a sheet material using beam cutting technology. Each one of the plurality of parts is formed by one of a plurality of two dimensional free form shapes, comprising at least a first shape. The method comprises a step of identifying at least one segment of the first shape, which segment prevents a part of the first shape to be positioned and cut so close to another shape in the plurality of shapes so that only one cut of the cutting beam is found between the parts. The method further comprises a step of modifying the segment to provide a modified first shape. The modified first shape comprises a modified segment, which is configured such that the modified segment allows a part of the first shape to be positioned so close to another shape in the plurality of shapes so that only one cut of the cutting beam is found between the parts whenever the shape of the parts allows it.

Abstract:
Method and apparatus enable cutting out shapes (S) preset in moving sheet material (10) by locating coordinates of one or more fiducials (F,F2...) in the sheet material (10) with a vision system (12). The fiducials (F,F2...) correspond to a pattern (P) for the preset shape (S). A cutting system (11) superimposes the pattern (P) relative to the located one or more fiducials (F,F2...) for cutting out the preset shape (S) while the vision system (12) is concurrently locating subsequent one or more fiducials (F,F2...) in the moving sheet material (10). The concurrent processes of cutting and locating subsequent fiducials (F.F2...) are repeated substantially continuously. Preferably, using two or more fiducials (F,F2...), distortion is detected and the pattern (P) can be remapped before cutting for accurate superposition of the pattern (P) and distorted preset shape (S).
