Helium polish software
What is new in the Helium Polish version 3.93?
  1. New parameters for StepCut / Trapezium:
    Girdle side width, Girdle side length, Girdle side width-based length
    Culet length, Girdle facets slope & azimuth angles
  2. Automatic control of holder height
  3. The new GIA cut grade estimations are available in the illustrated report for brilliant
  4. Fixed bug

1. New parameters for StepCut / Trapezium

  • Girdle side width - widths of narrow Girdle facets
  • Girdle side length - lengths of long Girdle facets
  • Girdle side width-based length - lengths of Girdle side along the normal to the largest Girdle side width
  • Culet length - Culet length on the projection into the girdle plane
  • Girdle facet angle - slope angle of the Girdle facet (ideal 90 o)
  • Girdle facet azimuth angle - azimuth angle of the Girdle facet

Please see example of the report:

The new parameters output into report with the follow bookmark names:

  1. Girdle side width 1 - GIRDLE_SIDE_WIDTH_MM_1
  2. Girdle side width 2 - GIRDLE_SIDE_WIDTH_MM_2
  3. Girdle side width 1 - GIRDLE_SIDE_WIDTH_PC_1

  5. Girdle side length 1 - GIRDLE_SIDE_LENGTH_MM_1
  6. Girdle side length 2 - GIRDLE_SIDE_LENGTH_MM_2
  7. Girdle side length 1 - GIRDLE_SIDE_LENGTH_PC_1
  8. Girdle side length 2 - GIRDLE_SIDE_LENGTH_PC_2
  9. Girdle side width-based length 1 - GIRDLE_SIDE_WIDTH_BASED_LENGTH_MM_1
  10. Girdle side width-based length 2 - GIRDLE_SIDE_WIDTH_BASED_LENGTH_MM_2
  11. Girdle side width-based length 1 - GIRDLE_SIDE_WIDTH_BASED_LENGTH_PC_1
  12. Girdle side width-based length 2 - GIRDLE_SIDE_WIDTH_BASED_LENGTH_PC_2
  13. Culet length - CULET_LENGTH_MM
  14. Culet length - CULET_LENGTH_WISE_PC
  15. Girdle facet angle 1 [degree] - GIRDLE_SIDE_ANGLE_DEG_1
  16. Girdle facet angle 2 [degree] - GIRDLE_SIDE_ANGLE_DEG_2
  17. Girdle facet angle 3 [degree] - GIRDLE_SIDE_ANGLE_DEG_3
  18. Girdle facet angle 4 [degree] - GIRDLE_SIDE_ANGLE_DEG_4
  19. Girdle facet azimuth 1 [degree] - GIRDLE_SIDE_AZIMUTH_DEG_1
  20. Girdle facet azimuth 2 [degree] - GIRDLE_SIDE_AZIMUTH_DEG_2
  21. Girdle facet azimuth 3 [degree] - GIRDLE_SIDE_AZIMUTH_DEG_3
  22. Girdle facet azimuth 4 [degree] - GIRDLE_SIDE_AZIMUTH_DEG_4

2. Automatic control of holder height

This feature adjust a holder height position if device have not stable holder height becouse of device temperature enlargement. The program do check-up automatic while the device is not scanning. If the system discoveres small or critical offset of holder the operator will see a warning with suggestions.

Critical offset

Small offset

It is be able to switch off / switch on the automatic control of holder height option, set time interval and etc.

To run the automatic control of holder height option insert the command line into the file HeliumBat.ini (or PacorBat.ini):
HeliumPolishHardwareControl [/source name] [/interval sec] [/extendedinterval sec]

The default settings are:

  • name - System\HolderContours.mmd
  • interval - 900 second
  • extendedinterval - 60 second

For work of automatic control option operator have to save five contours in the file System\HolderContours.mmd in advance. The countours should be saved in the motor pozition Rx=0.

The system try to check up holder height every 15 minutes. If the system can not make check-up it will try to check every minute. If it still unsuccessfully the program will wait a finish of scanning, block working and suggest to make check-up.

It is possible to put aside cheking of Holder Height for 30 minutes. Use the panel Helium Hardware Test Control. Select "Block Continious Holder Control".

To change the values of small and critical offset be able in the System Settings panel. Open the panel from Start / Inner/ Registry. Select Vertical Holder Offset.

Critical offset parameters

0.0050 mm
0.5000 px

For HP 1:2 Critical offset is near 0.015 mm = 0.005 mm + 0.5 px

Small offset parameters

0.0010 mm
0.1000 px

For HP 1:2 Small offset is near 0.002 mm = 0.001 mm + 0.1 px

It is strongly recommended do not change these parameters!

3. The new GIA cut grade estimations are available in the illustrated report for brilliant

The GIA cut grade estimation for Star facet length is available. Please see Star : Uper ratio section.

Also you can view the GIA estimations in the illustrated report for the follow parameters since version HP 3.91:

  • Girdle valley
  • Girdle bezel
  • Length girdle facet
  • Crown height
  • Total depth

Please see example of the Illustrated report:

4. Fixed bug

Crown corner angles were missed in the Helium Polish MS Word report for Princess. It is fixed in this version.
