4、 Software functions


1. CNC programming for automatic measurement: software is used to control the worktable and z-axis movement direction of the measuring instrument, making the measurement more convenient. The optional joystick control makes the operation more user-friendly. According to the measured size of the customer's products, measurement programming can be carried out. After the measurement path is saved, batch automatic measurement can be carried out, greatly improving the measurement efficiency;


2. Set the number of repeat operations for automatic measurement: measure the size of the same product to be tested, and set the number of repeat operations for automatic measurement, so it is unnecessary to repeat drawing and marking each time, saving time;


3. Optical focus: the computer automatically determines the focus plane of each time, so as to ensure the reproducibility and accuracy of measurement when the focus is changed;


4. Optical focusing height measurement: through the optical focusing function, the z-axis height is automatically calculated by software;


5. "Full picture" navigation and positioning window: it can browse all the drawn pixels in real time, and let the mouse click where to go, and let the measured data be in control;


6. "Browse" window: it can observe the whole drawing of workpiece and has the zoom function similar to AutoCAD;


7. Annotate in browse view: you can annotate directly in browse view;


8. Subpixel edge finding: let the software refresh in real time, track the mouse in real time, automatically capture the closest point of the mouse from the clearest edge, and save the mapping time to a greater extent;


9. Automatic graph capture: it can automatically scan the edge of line, circle and arc and obtain the graph automatically; custom circle: it can customize the standard graph according to the customer's needs (the center coordinate, diameter and radius of the circle are defined by the customer). Then compare the standard circle with the workpiece in the image to find the error between the workpiece and the standard figure;


10. Custom line segment: the customer defines the starting point coordinate, length and rotation angle of the line segment, and then makes overlapping comparison with the workpiece in the image, so as to find the error between the workpiece and the standard drawing;


11. Mark: any geometric dimension (diameter, radius, angle, distance between two lines, distance from point to line, distance between two circles, etc.) on the plane can be measured;


12. Coordinate annotation: mark the coordinate position of any point on the pixel based on the set coordinate origin (0, 0);


13. Self setting customer coordinates: you can set the coordinate origin (0, 0) on the actual workpiece in the image according to the customer's own needs, and then mark the X and Y coordinate positions of this point on any point of the screen based on the (0, 0) point;


14. Drawing: the actual workpiece shape in the real-time image can be described to form a complete engineering drawing, and the drawing method is similar to AutoCAD;


15. Operation number: the outline of the product can be easily traced, and the traced figure can be transferred to AutoCAD and modified to form an engineering drawing;


16. Set pixel color: all pixel colors drawn and marked can be changed to make it easier to distinguish and recognize;


17. Auto capture each node on the pixel: it can automatically capture the starting point, middle point, end point of the line and the three nodes on the intersection, center and circumference of the two lines, which are used for auxiliary annotation drawing and other application functions;

19. Setting tolerance: it can be set that the actual dimension of the product is out of range, otherwise, it will be warned with red background;


20. Send to AutoCAD: it can directly output the pixels described in real-time image according to the actual workpiece shape to AutoCAD;


21. Save high pixel photos: it can save clearer mapping elements and product photos, and observe the saved pictures in the drawing software in a larger multiple;


22. CCD correction: it compensates the errors produced in CCD production to make the measurement more accurate;


23. Grating scale correction: the error caused by grating scale shall be compensated to make the measurement more accurate;


24. Z-axis correction: compensate the movement deviation of z-axis to make the measurement more accurate;
