ABSTRACT:
An improved automatic lens grinding machine and process for shaping lenses to fit any particular glasses frame.
The machine includes a recording assembly by which the pattern of a glasses frame which will hold a lens is recorded on a heat or photosensitive substrate. The paper and lens are mounted on a carriage assembly which is movable into and out of a grinding position adjacent a grinding assembly. When positioned in the grinding position, grinding is under control of a scanner assembly and a control circuit. Thus, the relevant process for automatically grinding a lens to fit any particular lens includes the steps of recording a desired pattern on a recording substrate, moving the lens into position to be ground, subsequently scanning the recorded pattern and generating signals indicating the presence or absence of the pattern earlier recorded on the heat or photosensitive substrate, sensing the contact pressure between the lens and the grinding stone and controlling the position for the lens to be ground with respect to a rotating grinder stone in response to the signals generated during the scanning and pressure sensing process.
