| 1 | Method of controlling an edger device, machine programmed to edge an ophthalmic lens blank, and computer program | US11511434 | 2006-08-29 | US07392108B2 | 2008-06-24 | Kurt William Schaeffer |
| The present invention relates to a method of controlling an ophthalmic edger device, and a machine programmed to edge and ophthalmic lens blank. A lens blank and an edger device for forming a groove in a peripheral edge of the lens blank are provided. A central processing unit is provided, which is operably associated with the edger device for controlling operation of the edger device. Processing instructions are transmitted from the central processing unit to the edger device, wherein the processing instructions comprise forming a groove in a peripheral edge of a lens blank, and removing lens material debris from the formed groove. | ||||||

| <P>PROBLEM TO BE SOLVED: To efficiently cut a channel having a depth greater than 1 μm in glass as a material to be cut by a ball end mill or a square end mill of cemented carbide. <P>SOLUTION: In a ball end mill working method, the ball end mill 1 is rotated at a high speed, and the channel at least 1 μm in depth is formed in the material 7 to be cut made of a vitreous inorganic material or a hard, fragile inorganic material by one cutting without damaging the material 7. Preferably, the rotary shaft 9 of the ball end mill 1 has a relative inclination angle θ in the feed direction of the ball end mill 1 in relation to the working side surface 11 of the material 7, and the ball end mill 1 is rotated at a high speed to cut the material 7. As a result, by using the ball end mill 1 of cemented carbide, the worked channel 5 of depth width 200 μm and depth 20 μm is formed in the glass substrate as the material 7 by one cutting. <P>COPYRIGHT: (C)2005,JPO&NCIPI | ||||||
