A NEW METHOD FOR MANUFACTURING CHAMFER FOR SINGLE AND MULITPLE PATTERNS BY DRILLING

摘要

The method describes the creation of blunt corners in manufacturing small boards/substrates/pieces, wherein the sharp corners have to be rounded-off for ease of handling or for placing inside a box. The method describes the creation of the blunt corner (a concave shaped cut-out) by the method og drilling, which is commonly carried out in all mechanical shops. This new method shows how the same effect as that of a costlier manual process or a punch operation are attained. In multiple patterns (where the smaller pieces are arranged as array or a matrix)the hole is drilled at the jinction of corners, which results in the blunt corners for all rhe boards/pieces which are meeting at that point. A preferred embodiment of the said invention is described in detail.
