Applications of CMM Technology in The Machinery Manufacturing

As the manufacturing industry developed rapidly, the demands on product quality are spiraling up. Especially in the field of  aerospace and automotive manufacturing, the size, shape and position of the precision parts have very high requirements.

The measuring principle of a CMM is to use the movement of the probe in three directions to measure the co-ordinate position of the object to be measured in three-dimensional space, and thus determine its shape and size. This is particularly important for the measurement of high-precision machining parts, as it provides extremely high measurement accuracy and ensures that the dimensions and shape of the part during manufacture meet the design requirements.

The CMM process involves controlling the probe through a control system that scans the surface of the object being measured and transmits the results to a computer for processing. The accuracy of this process is directly related to the quality and performance of precision machined parts.

Aerospace

Coordinate measurement technology was first used in the aerospace field, as one of the important tools for the aircraft components manufacturing, coordinate measuring machine has high precision, high efficiency and high stability characteristics, so that it is widely used in aerospace.

Coordinate measurement technology is not only able to detect the accuracy of aircraft components in the aerospace field, but also can detect the quality of the surface of the aircraft components, perpendicularity and flatness and other key technical parameters, under the coordinate measurement technology, which provides great convenience for the production and inspection of aircraft components.

In the aerospace field in the application of three coordinate measurement technology, the overall shape of the parts can be detected, clear aircraft parts of each corner of the position and size, effectively improve the aircraft manufacturing link involves three-dimensional geometric parameter accuracy and effectiveness, and then enhance the aerospace field of aircraft parts production link of accuracy and efficiency.

Automobile manufacturing field

Coordinate measurement technology in the field of automotive manufacturing also has a wide range of applications. Coordinate measurement technology applied to the field of automobile manufacturing, can effectively detect the accuracy of automobile parts, such as car body and engine.

Through the three coordinate measurement technology can effectively enhance the accuracy of the car body and engine, for the production of key automotive components to provide a certain level of protection, and then to enhance the stability and safety of the automobile driving process to lay a solid foundation, and in the process of subtle enhancement of automotive emissions.

Mechanical manufacturing field

Coordinate measurement technology in the field of machinery manufacturing also has a wide range of applications. The application of coordinate measurement technology in the field of machinery manufacturing can effectively improve the accuracy of metal parts inspection work in the field of machinery manufacturing.

Through the application of coordinate measurement technology to mechanical parts in the field of mechanical manufacturing, with the support of coordinate measurement technology, it is easy for surveyors to analyse their three-dimensional shape and size. If the three-dimensional shape and size of the mechanical parts have certain errors, the measurement personnel can propose a series of measures to make timely and effective corrections according to the results.

Therefore, the application of three coordinate measurement technology in the field of mechanical manufacturing, not only can improve the accuracy of mechanical parts in the field of mechanical manufacturing, but also can improve the performance of mechanical parts, and then achieve the purpose of increasing the life of mechanical parts.

Electronic manufacturing field

The application of coordinate measurement technology in the field of electronic manufacturing can effectively improve the precision and quality of electronic components involved in the field of electronic manufacturing, and thus effectively improve the accuracy of the field of electronic manufacturing.

Coordinate measurement of electronic components can accurately and effectively measure the size, shape and structure of electronic components and other parameters. And effectively improve the accuracy of the measured parameters, optimise the design process and production process of electronic components in the field of electronic manufacturing, so as to improve the quality and quality of electronic components in the field of electronic manufacturing.

Medical equipment manufacturing

The application of coordinate measuring technology in the field of medical equipment manufacturing can provide a good guarantee for improving the production quality and precision of medical equipment. In the medical equipment manufacturing, the staff need to involve a variety of components and parts of the accuracy to verify, such as mechanical components, metal parts and electronic components.

Coordinate measurement technology can be based on the different needs of medical manufacturing, based on the actual needs of a variety of materials for testing, to ensure that the overall size and accuracy of medical equipment manufacturing equipment. Or very small structure, organisation, its quality can meet the relevant needs of medical equipment, and thus to improve the quality of medical equipment manufacturing to provide a good help.

Example of free-form surface measurement

As the use of coordinate technology becomes more and more common in the CNC industry, especially with the proliferation of free-form surfaces of all kinds, it is important to ensure the quality of free-form surface measurements by using higher precision machining modes in order to ensure the validity and accuracy of inspections.

For example, when applying the coordinate measurement technology to free surface measurement, a new space coordinate should be established according to the characteristics of the free surface before applying the coordinate measurement technology to ensure that the deviation between the measurement result and the theoretical calculation result is the same at the same point. Therefore, it is necessary to determine a new spatial coordinate on the new space to achieve the purpose of determining the accurate orientation of the spatial coordinate.

When measuring the mould, the processing accuracy should be ensured. The processed mould is used as the basis to construct a new coordinate system. By comparing the measured curve with the model curve, the inspection model is analysed, so as to construct a better three-dimensional solid model and effectively improve the accuracy of the 3D model.

Using the coordinate measurement, the whole mould is checked in advance, each inspection point is divided, the final data collection is completed, and then the point-triggered inspection is carried out on the coordinate according to the inspection plan.

Conclusion

Coordinate measurement technology as a modern machinery manufacturing industry, one of the important measurement technology, optics, mechanics and electronics and other high-tech technology in one. As a more efficient automated measurement technology, the three coordinate measurement technology is applied to the modern machinery manufacturing industry, replacing the traditional single production mode, and comprehensively improving the manufacturing level of modern machinery manufacturing industry.
