XYZ Test-bed and mobile control

The system provides XY electric mobile sample table and Z-axis control:

1. XY stroke: 50mm*50mm mesa size: 200mm X180mm, displacement repetition accuracy < 2um; XYZ displacement resolution can reach 2um;

2. The moving speed of XYZ is adjustable.

3. You can click the mouse to control the movement, or move up or down by inputting the distance of the movement.

4. The rocker can be used to control the movement of XY and Z, and the position can be feedback in time.

Loading mode and path setting

A variety of ways to ensure that users can still obtain satisfactory measurement results when the sample is not placed vertically or horizontally.

Two-point method: the moving direction of the object can be specified by clicking two points on the sample image at will.

Normal mode: Normal line tangential to the edge of the specimen is selected as the moving direction of the object platform.

Angular bisector: The direction of the bisector is used as the moving direction of the sample through the selection of the angle.

Arbitrary point mode: the mobile platform is placed at any position, loading point is added, and then loading and measuring once.

Loading at any point: Double-click at any position of the platform, the platform automatically moves the point to the center of the pressure head field of view, loading and measuring.

Path adjustment: For the selected path, horizontal mirror, vertical mirror, 90 degrees, 180 degrees, arbitrary angle rotation, position translation and other operations can be carried out.

Fully automatic measurement

The hardness value is calculated by point-by-point automatic loading, auto-focusing and auto-indentation measurement according to the set loading path, and the hardening curve is drawn.

Camera and calibration management

13 million pixels USB2.0 CMOS dedicated to microscopic measurement cameras

2. Camera can be calibrated by hardness calibration block or calibration ruler

3. In order to improve the accuracy of measurement, different test forces can be calibrated separately and the system can be loaded automatically.

Hardness Value Conversion and Correction

Hardness conversion: Vickers hardness values measured can be converted to other hardness values such as HB, HR, etc.

Data statistics

Automatically calculating the mean and variance of hardness

Measurement algorithm

1. Leading automatic reading technology - leading automatic reading technology, not only can obtain sub-pixel, high precision and high repeatability results, but also can be applied to general indentation images, even including a small amount of rust, scratches, uneven light, shallow corrosion images, measurement speed is very fast;

2. Unique manual point extraction and automatic point finding technology - users can pick up approximate points near the four indentation vertices, the system automatically distinguishes the best vertex position and reads directly, which meets the common user's habits and greatly reduces the user's labor intensity;

3. General manual measurement methods, including 4-vertex measurement, 2-diagonal measurement, etc. When measuring 4 vertices, 4 vertices can be selected according to any order, which is convenient for users.

Hardening curve

Automatic drawing of hardening curve:

Data storage

The original measurement data and images can be saved in a document for subsequent calls and reports; a file holds all the data of a measurement.

Test report

Automatically generate WORD or EXCEL document reports; report formats can be customized; standard formats include hardness values, statistics, indentation images, and hardening curves for each single measurement point.

Knoop hardness

It can be set to Knoop hardness measurement.
