Title: Polishing surface teaching method for polishing device
Inventor: KAWADA KENICHI
IPC: G05B19/4103
Filed: 1995-06-13
Abstract: PURPOSE: To easily and quickly teach a polishing surface by interpolating parts set among the teaching points arrayed in a 1st prescribed direction by a straight line and interpolating the parts set among the teaching points arrayed in a 2nd prescribed direction orthogonal to the 1st direction by a linear expression respectively. CONSTITUTION: The parts set among the teaching points arrayed in a 1st prescribed direction are interpolated by a straight line in response to a fact that an optional point is shown on a polishing surface. Then the parts set among the teaching points arrayed in a 2nd prescribed direction orthogonal to the 1st direction are interpolated by a linear expression. Thus the polishing surface is expressed in plural functions and therefore the interpolation processing is simplified. Thereby, the teaching time of the polishing surface is extremely shortened and the interpolation processing is carried out in real time with no use of a processor having an especially high processing function.  Furthermore, an operator can intuitively recognize whether the spaces should be increased or reduced among the teaching points since the parts set among these points are interpolated by a straight line and a linear expression. As a result, the polishing surface can be taught with considerably high accuracy.

The piece 1 is placed between an upper and a lower molds 3, 4 which have such curved surfaces that the piece 1 should be worked into a desired shape. The resin 2 is then thermally set at a high temperature or room temperature. At that time, pressure on the resin may be as low as about 0.1kg/cm 2 . When a prescribed setting time has elapsed, the upper and the lower molds 3, 4 are separated from the piece 1. A soft foamed slab piece 1" coated with the thermally set resin 2 on the bottom is picked out. The piece 1" has such a curved shape that its bottom is contracted but its top is expanded.
