Title:
BEVELLING APPARATUS AND METHOD OF BEVELLING
Document Type and Number:
WIPO Patent Application WO/2011/052093
Kind Code:
A1
Abstract:
A bevel is prepared in two cutting paths wherein the position of the first cutting path is corrected at the end of the path before the second cutting path is performed. The object of the invention is to correct the end position of the first path with a high accuracy regardless of a work profile. A light projector projects slit light onto a base metal. An image pick up means picks up images including a cross image projected on the base metal by the laser slit light. The image signals are sent to a controller after the first path has been completed and before the end of the second path. The controller calculates positional errors of a corner as well as an angle of rotation in the X-Y coordinate based on the signals and corrects data stored for controlling the second path based on the calculations in terms of X- Y coordinate data.
