titleGrind depth


Info
This parameter is applicable to the following cuts: All Cuttings

How much should we grind parallel to the solution table to reach a new scan table - the one used to set a stone on for bruting.

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).

Usage and Examples

Information is used during grinding.
