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).

Calculation

Calculated after the scan is bruted by finding the distance between New scan table and C8 reference plane ("line"), where:

  • New scan table is parallel to the solution table and positioned differently depending on conditions (see Grind depth calculation in the detailed description).
  • C8 reference plane ("line") is a crown main facets reference plane.

Usage and Examples

C8 reference line information is used during grinding.
