Abstract
An automatic grinding system and method for grinding a surface having a predetermined pattern of raised and lower regions includes sensing the width of at least one of those regions; determining the height of the raised region above the lower region in response to the sensed width; and selecting the grinding speed and force and the velocity of the grinder over the surface in response to the determined height of the raised region.
Claims16
An automatic grinding system for grinding a surface having a predetermined pattern of raised and lower regions, comprising:
- means for grinding the raised regions down to the level of the lower regions, said means including a grinder, said grinder having a flexible member for supporting a grinding medium selected to maintain the surface of the raised regions flat during the grinding of the surface;
- means for controlling the grinding force, the grinding speed and the velocity over the surface of the means for grinding;
- means for sensing the width of at least one of the regions;
- means, responsive to the means for sensing, for determining the height of the raised regions above the lower region;
- and
- means, responsive to said means for determining the height, for driving said means for controlling to set the grinding speed and force and the velocity over the surface of the means for grinding.
An automatic grinding method for grinding a surface having a predetermined pattern of raised and lower regions, comprising:
- sensing the width of at least one of those regions;
- determining the height of the raised region above the lower region in response to the sensed width;
- selecting the grinding speed and force and the velocity of the grinder over the surface in response to the determined height of the raised region;
- and
- selecting the grit size of the grinding medium to obtain a predetermined surface shape of the ground surface during grinding.
