What Is CMM Machine: Components, Uses, and Benefits in manufacturing prototypes or real parts of all products.

As a general-purpose measuring instrument, CMM has been widely used in precision measurement and product quality control due to its advantages of high precision, strong function and convenient operation.

CMM is one of the most effective ways to measure and obtain dimensional data, because it can replace a variety of surface measurement tools and expensive combination gauges, and reduce the time required for complex measurement tasks from hours to minutes, greatly Improve measurement efficiency.

The coordinate measuring machine​ is a measuring system that detects the three-dimensional coordinates of the surface points of the workpiece through the relative movement of the probe system and the workpiece. By placing the measured object in the measurement space of the CMM, the coordinate position of each measuring point on the measured object is obtained by using a contact or non-contact detection system.

The three-coordinate measuring machine is a new type of high-efficiency precision measuring instrument developed in the past 50 years. Its emergence, on the one hand, is due to the high-efficiency processing of automatic machine tools and CNC machine tools, and the processing of more and more complex-shaped parts requires fast and reliable measuring equipment.

With the development of modern manufacturing industry, the design requirements for mechanical manufacturing products are getting higher and higher, and the three-coordinate measuring instrument has been widely used in many industries. Improve the efficiency of the three-coordinate measuring instrument, which can make the detection results more effective.

In addition to the four geometric errors of positioning error, straightness error, angular motion error, and perpendicularity error, the CMM​ also has four geometric errors due to force deformation, thermal deformation, measurement system, probe system, control system, data recording and processing.

CMMs are robust and easy to maintain, but they are not completely maintenance-free. Sensitive CMM measurement systems require a certain level of cleanliness. Fine dust particles on probe assemblies or standard ceramic balls can affect measurement accuracy. In addition, the measuring table must be maintained daily. Maintenance measures include regular cleaning and inspection of several components.

The work plane was not noticed. Especially when the programming hand picks the coordinates for the initial construction, if the working plane is not switched to the straight line used to build the coordinate system, it is likely to cause the rotation direction to deviate greatly or be invalid, and almost all such programs cannot run or collide.

Reverse engineering is based on existing products and materials, digesting and absorbing, reforming and innovating, and improving and optimizing the production process.

The coordinate measuring instrument and the image measuring instrument are widely used with the most advanced measurement technology.

During the calibration, the probe of the coordinate measuring machine will be affected by many factors, such as: dirty stylus, wrong input of stylus length, wrong input of sphere diameter, etc., which will affect the accuracy of the measurement.
