1. A method of producing a building panel with a curved edge portion, the building panel including a wood-based core and a decorative surface, wherein the decorative surface comprises a wood veneer or a paper laminate layer, the method comprising: heating an edge of a building panel;lubricating a press tool at an exterior surface of the press tool that is configured to compress the edge of the building panel, with an oil or grease; andafter lubricating, compressing the edge of the building panel with the press tool to a curved edge shape so that at least the core at the edge of the building panel has a curved shape, wherein the edge of the board is compressed more than 0.5 mm, and wherein said compressing step compresses both the decorative surface and the core. 2. The method as claimed in claim 1, wherein the method comprises heating the tool. 3. The method as claimed in claim 1, further comprising moving the building panel relative to the tool via a conveyor. 4. The method as claimed in claim 3, wherein the building panel is moved at 50 m/min or higher. 5. The method as claimed in claim 1, wherein the edge is compressed to a depth of about 0.7 mm or more. 6. The method as claimed in claim 1, wherein the edge is compressed to a depth in the range of about 0.5 mm to 1 mm. 7. The method as claimed in claim 1, wherein the curved edge has an elliptic shape. 8. The method as claimed in claim 1, wherein the curved edge has a circular shape. 9. The method as claimed in claim 1, wherein the decorative surface comprises a wood veneer. 10. The method as claimed in claim 9, wherein the wood veneer extends to an outer edge of the curved edge shape at the curved edge portion. 11. The method as claimed in claim 1, wherein the core comprises HDF or MDF. 12. The method as claimed in claim 1, wherein the decorative surface comprises a paper laminate layer. 13. The method as claimed in claim 12, wherein the paper laminate layer comprises a resin and a paper sheet. 14. The method as claimed in claim 12, wherein the paper laminate paper extends to an outer edge of the curved edge shape at the curved edge portion. 15. The method as claimed in claim 12, wherein the core comprises HDF or MDF. 16. The method as claimed in claim 1, wherein the press tool is rotatable and is configured to rotate when applying pressure on the edge of the building panel. 17. The method as claimed in claim 1, wherein the lubricant is an oil selected from the group consisting of synthetic teflon oil, mineral oil and organic oil. 18. The method as claimed in claim 1, wherein the decorative surface extends to an outer edge of the curved edge shape at the curved edge portion. 19. The method as claimed in claim 1, wherein, the press tool having a surface grinded to a roughness of about 0.2 Ra. 20. The method as claimed in claim 1, wherein said compressing step compresses both the decorative surface and the core so that the core and the decorative surface have a curved shape, and wherein the decorative surface extends to an outer edge of the curved edge shape at the curved edge portion. 21. A method of producing a building panel with a curved edge portion, the method comprising: heating an edge of a building panel;lubricating a press tool; andafter lubricating, compressing the edge of the building panel with the press tool to a curved edge shape,wherein the building panel comprises a decorative surface and a wood-based core, and wherein the decorative surface comprises a wood veneer, andwherein said compressing step compresses both the decorative surface and the core so that the core and the decorative surface have a curved shape, and wherein the decorative surface extends to an outer edge of the curved edge shape at the curved edge portion. 22. The method as claimed in claim 21, wherein the building panel has a planar surface, including the edge portion, prior to compression, and wherein the step of compressing the edge of the building panel with the press tool involves compressing the entire edge portion from the plane of the planar surface to the curved edge shape. 23. A method of producing a building panel with a curved edge portion, the method comprising: heating an edge of a building panel;lubricating a press tool at an exterior surface of the press tool that is configured to compress the edge of the building panel, with an oil or grease, the press tool having a surface that is grinded to a roughness of about 0.2 Ra; andafter lubricating, compressing the edge of the building panel with the press tool to a curved edge shape,wherein the building panel has a planar surface, including the edge portion, prior to compression, and wherein the step of compressing the edge of the building panel with the press tool involves compressing the entire edge portion from the plane of the planar surface to the curved edge shape,wherein the building panel comprises a decorative surface and a wood-based core, the core being compressed to have a curved shape by the press tool,wherein the decorative surface comprises a wood veneer or a paper laminate layer comprising a resin, andwherein the decorative surface extends to an outer edge of the curved edge shape at the curved edge portion. 24. The method as claimed in claim 23, wherein the decorative surface comprises the wood veneer. 25. The method as claimed in claim 23 wherein the decorative surface comprises the paper laminate layer. 26. The method as claimed in claim 23, wherein the lubricant is an oil selected from the group consisting of synthetic teflon oil, mineral oil and organic oil. 27. A method of producing a building panel with a curved edge portion, the method comprising: heating an edge of a building panel;lubricating a press tool; andafter lubricating, compressing the edge of the building panel with the press tool to a curved edge shape,wherein the building panel comprises a decorative surface of wood veneer or paper laminate and a wood-based core,wherein the decorative surface extends to an outer edge of the curved edge shape at the curved edge portion, andwherein the core at the edge of the building panel is compressed by the press tool to have a curved shape.
