Alignment tool, cutting arrangement and method for treatment of a workpiece

An alignment tool for guiding cutting of a leading edge of a rotor blade of a wind turbine, the alignment tool comprising:

• at least one fixation means for fixing the alignment tool proximate a trailing edge of the rotor blade, wherein the at least one fixation means is a structure attachable to a first surface and a second opposing surface of the rotor blade, and the structure is selected from the group consisting of:
• a clamp arrangement, and at least one suction cup, the structure including a first loop configured to be proximate the first surface when the structure is attached to the rotor blade, the structure including a second loop configured to be proximate the second opposing surface when then the structure is attached to the rotor blade;
• and
• a first rope, chain, hook-and-loop fastener and/or tension belt attached to the first loop;
• a second rope, chain, hook-and-loop fastener and/or tension belt attached to the second loop;
• at least one guiding structure operably connected to the fixation means, wherein the guiding structure is configured to embrace the leading edge of the rotor blade and includes at least one groove or at least one edge that is configured to provide guidance for a cutting edge of a cutting apparatus, and wherein a first end of the guiding structure is attached to the first rope, chain, hook-and-loop fastener and/or tension belt and a second end of the guiding structure is attached to the second rope, chain, hook-and-loop fastener and/or tension belt.
