Introduction to Measurement Software: 

1:Direct element measurement

It can measure 12 types of elements (points, lines, circles, arcs, ellipses, rectangles, slots, O-rings, distances, angles, open curves, and closed curves). 

There are various measurement methods (automatic discrimination measurement, point sampling measurement, comparative measurement, tolerance comparison measurement, preset element). 

There are various single-point collection methods: mouse click collection, crosshair edge-finding collection, magnification collection, straight line collection, and automatic mouse capture. 

2. Indirect measurement 

The distance between two elements, the included angle of two sides, the flatness of a plane formed by multiple points, and so on, can all be achieved through the software's construction function. The elements that can be constructed include: points, lines, circles, arcs, angles, planes, etc. 

3. Image measurement of height difference 

First, focus on one plane. The software will record the ZUI high point data of this plane. Then, focus on another plane. The software will also record the data of the next point. The software calculates the height difference between the two planes based on the coordinates of the bright spots, with an error less than 0.005mm. 

4. Scanning Function 

The contour of a workpiece can be scanned and then transferred to CAD for editing. The design drawing is obtained, and thus the data of the workpiece is acquired, achieving two-dimensional reverse engineering. 

5. Map Function 

A complete picture of a workpiece can be taken, and measurements and annotations can be made on the picture. The picture can be stored and retrieved for measurement. 

6. Macro Measurement 

The macro measurement function is to associate a series of the same "construction measurement" and construction commands with a button. By clicking the button, the macro measurement function will start and automatically complete the construction actions, reducing the number of times the user operates the mouse and improving work efficiency. 

7. Template Measurement 

The template measurement method, which is also a type of visual inspection method, mainly relies on the user's eyes to visually assess whether it is qualified, similar to the standard specification board used in projectors. 

Template measurement mainly includes cross-line templates, grid templates and concentric circle templates. 

The cross-line template is mainly used to measure angles, the grid template is mainly used to measure distances, and the communication group template is mainly used to measure circles. 

8. Predefined Elements 

The software can freely preset elements in either the mechanical coordinate system or the working coordinate system. 

9. Establishment of Coordinate System 

Multiple workpiece coordinate systems can be established freely. Then, the crosshair rotates along with the coordinate system, so there is no need to align the components. Another advantage of establishing a workpiece coordinate system is that it maintains the same reference as the drawing, allowing for the measurement of X and Y directional distances. 

10. Data Output 

The measured data does not need to be copied by hand; it can be directly exported to Word, Excel, Tct, Cad and then printed. 

11. Professional SPC Statistical Analysis 

Importing measurement data into SPC can generate commonly used control charts. Control charts for measured values include: average range control chart, average standard deviation control chart, median range control chart, individual value and moving range control chart, histogram, CPK trend chart, specification and process standard control chart, process status analysis chart, process recommendation analysis chart, etc. The generated graphs can be judged using the eight major judgment rules, allowing users to promptly understand the product quality status. For count data, single quality monitoring is also provided to promptly understand the product status.

What is a semi-automatic 3D probe image measuring instrument?

A semi-automatic 3D probe image measuring instrument, commonly known as a "hybrid" or "2.5D + probe" measuring instrument, is a semi-automatic coordinate measuring device that integrates a high-precision optical vision system with a three-dimensional contact probe system. 

Its core design concept is "complementarity". Traditional 2D image measuring instruments are good at measuring the two-dimensional planar dimensions of workpieces (such as length, diameter, and angle), but they often struggle with elements that cannot be clearly imaged, such as edge chamfers, internal features of deep holes, and those requiring the measurement of three-dimensional geometric tolerances such as flatness, perpendicularity, and cylindricity. The semi-automatic 3D probe image measuring instrument addresses this pain point through the following methods: 

1.Optical system (image measurement): By using high-resolution CCD cameras and zoom lenses, the edges of workpieces can be captured rapidly. The precise contours are measured through automatic edge-finding technology. This method is non-contact and non-destructive, making it particularly suitable for measuring soft or easily deformable workpieces such as plastic parts, rubber parts, and PCB boards. 

2.Probe system (contact measurement): It integrates contact probes from brands such as Renishaw. When measuring three-dimensional spatial dimensions (such as step height, hole depth, taper) or conducting probe measurements, the probe touches the surface of the workpiece, and the software records the points and fits them to form three-dimensional elements. 

3.Semi-automatic control: Unlike fully automatic CNC image measuring instruments, semi-automatic models typically feature high-precision manual control (or low-friction smooth rod transmission) on the X and Y axes, facilitating rapid positioning. On the Z axis, where focusing accuracy is extremely critical, electric servo control is employed to achieve automatic focusing and automatic height measurement. This design retains the flexibility of manual operation while eliminating the errors associated with manual focusing. 

Why choose "image + probe" composite measurement?

Many users often face a dilemma when purchasing inspection equipment: should they buy a high-precision image measuring instrument or a coordinate measuring machine? The emergence of semi-automatic 3D probe image measuring instruments precisely offers a third option - multiple uses in one machine, complementing each other's strengths. 

1.Solving the problem of what optical measurement cannot achieve

Optical measurement relies on the contrast of object edges. When dealing with fully smooth surfaces, highly reflective mirror surfaces, the inner walls of deep holes, or threads, the image system has difficulty accurately locating. At this time, the touch measurement function of the probe becomes crucial. The operator only needs to control the probe to touch the feature points to accurately obtain the spatial coordinates. 

2. Achieving the assessment of three-dimensional geometric tolerances

Image measurement typically only provides evaluations within a two-dimensional plane. However, in practical engineering applications, we often need to measure the perpendicularity of a circle relative to a reference plane, or the cylindricity of a cylindrical surface. By taking points with a probe in multiple sections in space, the software can fit three-dimensional features such as cylinders, cones, and planes, and conduct a comprehensive analysis of form and position tolerances. 

3. Enhance Z-axis measurement accuracy

Conventional image measuring instruments rely on optical focusing (the point of highest clarity) when measuring height. This method is highly subjective and limited in accuracy due to the influence of the operator. Semi-automatic models, through electric control of the Z-axis and in combination with probe contact or laser assistance, can enhance the Z-axis measurement accuracy to the level of (5.0 + L/200) μm, far surpassing simple optical focusing.
