There are three kinds of measurement methods in general point measurement: direct measurement, program measurement and self-learning measurement.

A Coordinate Measuring Machine (CMM) is a device used to accurately measure the geometry of an object. According to different measurement methods, CMM can be divided into the following categories:

If the CMM uses a triangular beam structure as its beam, it may have the following adverse effects on the accuracy.

As an important part of mechanical structure, the design and shape of the beam directly affect the stability and bearing capacity of the structure. A triangular beam is a common beam design that consists of three interconnected triangles, often used to support and carry heavy loads. Although triangular beam structures have advantages in some respects, they may also have some structural defects.

A typical CMM inspection system consists of four parts: the measuring probe quill, the probe extension, the stylus adjustment or extension, and the stylus.

In the process of product testing, if it is found that the test data of the same program or the same part during multiple tests are greatly different, the output is inconsistent, or it is different from the actual assembly situation, it needs to be checked and analyzed from several aspects. Here are the main points.

In the modern manufacturing industry, CMM is increasingly used in the production process, making the goal and key of product quality gradually change from final inspection to manufacturing process control.

When using the coordinate measuring machine for measurement, if the measurement deviation is too large, then please follow the following method to solve the problem.

The working process of a CMM generally includes preparation, select measurement program, set measurement parameters, data processing, data processing, follow-up processing.

There are many kinds of CMM probes, mainly divided into fixed, manual rotation, manual rotation automatic indexing, automatic rotation automatic indexing and general detection system.

CMM focuses on geometric measurements in three-dimensional space, while profilometers focus on surface profile and roughness. CMM are suitable for a wider range of industrial applications, while profilometers are more focused on surface characteristic analysis. 

At this glorious moment, we jointly celebrate the 75th anniversary of the founding of the People’s Republic of China.
