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 the 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.

8. A method of cutting a sheet-like piece of metal 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, characterized in that 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, the information on the outlines of the piece is input into the positioning system, where positioning data is created by selecting at least one type of a small part and, when applicable, adding a desired number of said at least one type of small parts into the outline image inside the outlines and the cutting paths are established and input into the control system of the cutting machine which determines necessary parameters for the cutting and on the basis of these the cutting of the piece into parts is carried out on said cutting surface under the control of the said control system according to given instructions. - View Dependent Claims (9, 10, 11, 12, 13, 14)
