Introduction
Gerard Lombard is a notable inventor based in Velaines, France. He has made significant contributions to the field of machining and optical lens surfacing. With a total of five patents to his name, Lombard's work showcases his expertise and innovative spirit.
Latest Patents
One of his latest patents is a method and multi-axis numerically-controlled machine for machining. This machining method utilizes a multi-axis numerically-controlled machine where a workpiece holder is rotated in a step-by-step motion around an axis. Rectilinear movements are produced between a tool and the workpiece holder along specific axes, while the tool is also rotated around another axis. These movements are controlled based on data corresponding to the required surface to be produced on a workpiece. The combination of these movements allows for the production of a spiral path of the tool on the workpiece surface, achieving the desired thickness at various points along the path.
Another significant patent is a workpiece holder apparatus for surfacing optical lenses. This apparatus is designed for use with a surfacing tool specifically for optical lenses, particularly afocal ophthalmic lenses. The workpiece holder features a chamber that receives an optical lens and is connected to a source of compressed air. An air cushion is established between the endwall of the chamber and the lens, allowing for precise control during the surfacing process.
