Coordinate measuring machine is a very efficient instrument, with it to measure roundness also has high accuracy, especially in the batch measurement can show its advantages, and, with the CMM to measure roundness, the workpiece does not need to be levelled and centred, reducing the detection error while saving a lot of detection time, so that the measurement error is limited to the error of the measuring machine itself and the influence of surface roughness, reducing the error Model. Coordinate measuring machine to measure the roundness of the main methods are:

1. Scanning measurement

If you want to grasp the complete shape, you can use the scanning method. When you use the scanning method, you get the complete contour and use the inclusive area method for evaluation. The scanning method is characterised by a slightly lower efficiency, but allows a detailed analysis of the part contour. Both methods can make accurate measurements of roundness, can be selected according to the actual requirements.

2. Single-point measurement

Single-point touch measurement method because of some discrete points, so the use of two times the method of calculation and evaluation. Calculated using the two-square method, the sampling point is generally an even number, and the average distribution. In the single-point method for roundness measurement, the number of sampling points can not be too small, otherwise it does not respond to the real situation of roundness, generally up to 16 points can be reflected in the basic contour shape of the measured circle, if in order to grasp the shape of the more stringent, can be appropriate to increase the number of measurement points, such as 24, 32 and so on. Sampling is generally used automatically, because manual sampling is inconvenient to control the vector direction. The single-point touch measurement method is characterised by high measurement efficiency and low wear and tear on the ball.

Measurement results show that, whether it is single-point measurement or scanning measurement, the measuring instrument can be obtained over and roundness instrument is very close to the results, indicating that the CMM measuring roundness has a high degree of accuracy. However, because the CMM generally use a spherical probe, the spherical probe is more sensitive to dirt, easy to cause false measurements, while the roundness of the instrument uses an axe-shaped probe, can pass through the dirt, so the dirt on it has less impact. So pay attention to the cleanliness of the workpiece when using the CMM.

Precise calculation, high repeatability

(A) software for edge extraction and lens distortion correction algorithms with unique patented technology, industry-leading.

(B) for the configuration of the surface light source independent research and development of the coaxial falling light source, to exclude human interference, the measurement of high precision can be guaranteed.

(C) can be comparable to the traditional imaging instrument measurement accuracy and repeatability.

A）Anyone can get started quickly, with or without operating experience can easily master.

(B) simple interface, measurement of intelligent, optimised for very simple operation steps, and real-time operation prompts.

(C) after the measurement can automatically record all the measurement data, a key to generate statistical analysis, you can print the measurement results for a variety of text formats.

Fresh software interface, rich functionality

(A) The software is divided into three functional modules: measurement setting, continuous measurement and statistical analysis, in which continuous measurement can be carried out in real time without pressing the button to determine whether it is NG/OK or not.

(B) provides up to 80 kinds of extraction and analysis tools, including [feature extraction] tools (such as the most valuable point, centre line, arc, peak circle, etc.), [auxiliary tools] (such as any point line circle, fit straight line, fit circle, tangent line, tangent circle, etc.), [intelligent labeling] tools, [shape and location tolerance] tools, special [application tools] (such as R angle, etc.) The accuracy of the flash measuring machine in the 3um (0.003mm), the accuracy of the flash measuring machine, the accuracy of the flash measuring machine in the 3um (0.003mm), the accuracy of the flash measuring machine in the 3um (0.003mm), the accuracy of the flash measuring machine in the 3um (0.003mm). Operation is simple and convenient, even if the operator is not familiar with the use of the instrument, but also in as little as 2-3 hours to operate proficiently, the biggest advantage is that you can import the product's CAD drawings into the software inside the software, the software automatically defaults to the programming process, reducing the time of personnel programming, so that customers can really experience the function of flash testing.
