Calculation By finding the distance between Plane A and New scan table, where: - Plane A goes through the point of the scan table farthest from the solution table and is parallel to the solution table.
- New scan table is parallel to the solution table and goes:
- through the point of the scan table nearest to the solution table - if this nearest distance is positive (that is when fully grind the existing scan table, the solution is not touched);
at the distance of 20 µm from the solution table - if this nearest distance is negative (that is when fully grind the existing scan table, the solution is broken); through solution table itself - if the maximum distance between the initial scan table and solution table is less than 20 µm (and nearest negative).
