Distance to Crown Safe line before grinding from New scan table

Calculation

Calculated after the scan is bruted by finding the distance between New scan table and Crown Safe line ("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).
  
• Crown safe line is Crown Safe Line calculated for New scan table plane.

Usage and Examples

Distance to new scan table (crown) information is used during grinding.

Reporting

Visualization in Appraisers

Distance to Crown Safe line aftersolution table is reached (that is, distance to Crown Safe line from solution table itself).

Calculation

Calculated after the scan is bruted by finding the distance between Crown safe plane ("line") and solution table, where:

• Crown safe plane ("line") is Crown Safe Line calculated for plan table plane.

Formal definition:

FACETING_SAFE_LINE_CROWN_AFTER_TABLE = CROWN_HEIGHT_MIN_MM

Usage and Examples

C8 reference line information is used during grinding.

Distance to Pavilion Safe line before grinding from New scan table.

Calculation

Calculated after the scan is bruted by finding the distance between New scan table and Pavilion safe 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).
• Pavilion safe line is Pavilion Safe Line calculated for New scan table plane.

Usage and Examples

Distance to new scan table (pavilion) information is used during grinding.

Visualization in Appraisers

Distance to Pavilion Safe line aftersolution table is reached (that is, distance to Pavilion Safe line from solution table itself).

Calculation

Calculated after the scan is bruted by finding the distance between Pavilion safe plane ("line") and solution table, where:

• Pavilion safe line is Pavilion Safe Line calculated for Plan (solution) table plane.

Formal definition:

• Find the pavilion facet with the lowest height, let us say its number is F
• Marking for Pav, mm = CROWN_HEIGHT_MM_<F> + GIRDLE_WIDE_BEZEL_MM_<F>

Usage and Examples

Distance to plane table (pavilion) information is used during grinding.
