Function introduction

• 1. The automatic recognition ability of diamond indentation image is significantly ahead of the existing mainstream hardness measurement software products.
• 2. Each functional area of the main interface can be dragged arbitrarily to form a personalized layout style.
• 3. Compatible with Knoop (HK) hardness measurement, Knoop Indentation can be automatically identified.
• 4. Besides automatic measurement, there are also three kinds of manual measurements: four point measurement, diagonal measurement and four side measurement.
• 5. Two calibration methods: hardness block calibration and optical calibration.
• 6. The calibration of standard hardness block supports multiple calibration and averaging.
• 7. The software will automatically select the best calibration coefficient for different resolutions, different objective lenses and different loads.
• 8. The best calibration coefficient is automatically selected according to different hardness values during hardness measurement.
• 9. During manual measurement, it has the function of magnifying glass, which is convenient to find the vertex position of indentation.
• 10. The indenter / lens offset calibration function is provided to eliminate the mechanical deviation between the indenter and lens and correct the overall system error, so as to improve the accuracy of hardness test results.
• 11. Support a variety of video capture devices, with a resolution of 1.3 million, 2 million, 3 million and 5 million digital cameras. Display the indentation video on the computer to capture and store images.
• 12. When measuring the hardened layer path sequence, there are many flexible initialization setting modes, which automatically save and import the previous path sequence. The measurement path can also be saved arbitrarily for reloading.
• 13. The measurement results are arranged according to the path sequence, and the corresponding hardened layer depth value and hardness change curve are generated.
• 14. It provides distance measurement and angle measurement functions, and can display multiple groups of distances and angles on video or images at the same time.
• 15. Built in hardness value conversion tools for various standards, with reference to GB, DIN, ISO, ASTM and other standards, it can achieve mutual hardness conversion between Vickers HV, Knoop HK, Rockwell: HRC, HRA, HRB, HRD, etc., Superficial Rockwell: HR15N, HR30N, HR15T, etc., Brinell: HBS, HBW, etc. Any conversion unit can be selected and listed in the result table.
• 16. Report content and format can be set flexibly, and word and EXCEL documents can be generated automatically. All results, indentation images, user-defined information lists, and user logos can be set to generate graphic reports.
• 17. Password and management authority can be set: ordinary operators can only measure hardness
• according to the set settings.
• 18. The software can automatically save the user's habitual settings, and keep the state of the last
• shutdown when it is next started.
• 19. The software is available in Chinese, English, German, Spanish and Russian (optional).
• 20. Hardness tester turret automatic control function.
• 21. Path planning function, 17 kinds of path planning can be set freely.
• 22. Area mode & continuous printing and testing function. For multiple indentations that may exist in the same field of view, the area mode can be selected. Only the indentations within the set range are considered during each measurement. When the area mode is enabled during the continuous test, the test interruption caused by multiple indentations in the same field of view can be avoided.
• 23. The surface correction function conforms to Table I and Table II of ASTM E384 standard, and provides the test and correction requirements of ball, rod and other surface parts.
• 24. During Knoop automatic identification and measurement, the indenter angle correction can be input, ASTM E384-11, SEC 10.7.2.1.
• 25. For the Vickers and Knoop measurement results, the effectiveness alarm function is introduced for the suspicious shape indentation that does not meet the ASTM E384 standard.
• 26. Multi sample panoramic scanning function, which can perform panoramic scanning on multiple samples, then make path planning on the panorama, and finally complete continuous printing and testing.
• 27. The scanning area can be set freely. For irregular samples, the scanning area can be set according to the shape to reduce the scanning area and improve work efficiency.
• 28. The CHD hardened layer test function can set stop conditions as required. When the test conditions are met, the test process will be interrupted in advance. The original purpose of this function is to save time after the CHD test reaches the limit of the hardened layer.
• 29. The calibration adopts the evaluation of error and repeatability to ensure that the calibration is qualified.
• 30. The automatic brightness function can automatically adjust the surface of the sample to the best state. The appropriate brightness can better distinguish the indentation from the surrounding, and help to identify the indentation vertex more accurately.
• 31. The minimum interval generates test points, which can obtain more detailed and accurate hardness distribution of the sample.
• 32. The built-in predetermined denture template can greatly save the setting time for complex and timeconsuming test points, especially for the measurement points of the toothed flank. All standard presets such as HK30 and HK0.5 can be implemented in one device. The corresponding reports are also stored.
• 33. Fracture toughness: the system allows the user to continue to measure the crack size aftermeasuring the normal hardness indentation (click the left, right, up and down extremes of the crackwith the mouse) to calculate the fracture toughness. The system displays three more columns in thehardness measurement result table: C1, C2 and KIC. C1 is the distance from the leftmost to therightmost end of the crack (unit: mm), C2 is the distance from the top to the bottom, the total crack length L = C1+C2-D1-D2 (D1 and D2 are the measured diagonal length of the indentation), the fracture toughness is calculated according to KIC = 0.0028 * sqrt (HV * F/L), HV is the measured hardness indentation, F is the test force unit: N, the unit of L is m, KIC unit: MPa m^1/2. Different calculation methods will be provided later. Like the indentation, the crack size will have a rectangular mark. The user can drag the mouse to modify any side of the rectangle, and the calculation result statistics will be automatically updated. The selection of fracture toughness will be displayed in the statistics column. If it is checked, the statistical result will be fracture toughness KIC. If it is not checked, it will be HV. The report (WORD and EXCEL) will automatically add C1, C2 and KIC columns. Note: when the fracture toughness is selected, the Knoop hardness above shall not be selected.
