The Development Trend of Coordinate Measuring Machine

1. High-precision

Since the development of CMM, it has been required to have high precision. At present, with the significant improvement of processing accuracy, this requirement is becoming more and more intense. There are many problems to be solved to improve the accuracy, the most important of which is the basic structure of the mechanical body. At present, CMM is still a Cartesian coordinate system composed of three orthogonal three axes. Similar to multi-axis automatic machine tools, it is very important to correctly choose the form of the measuring machine body (bridge or gantry). In general, when measuring small workpieces, the bridge is the most advantageous. In order to achieve higher precision measurement accuracy, in the field of medium size measuring machines, the high-precision bridge coordinate measuring machine produced by our company can achieve a high precision of 0.7um.

2. Automation (computer numerical control)

From the recent products launched abroad, the measuring machine numerical control system has a clear bipolar development trend: high-end and cheap. High-end measuring machine CNC system is the product of traditional measuring machine manufacturers, they supply large enterprises with higher price models, these enterprises have a high level of Computer application, cheap system is the product of some companies mostly using DCC(Directly Computer Control) technology, In order to reduce costs, while meeting the requirements of use. In addition, the purpose of computer numerical control is not simply to save manpower by using peripherals and software, but to use continuous profiling measurement using profiling probes to evaluate the shape of surfaces and to eliminate human error.

3. Become an integral part of the manufacturing system

From the perspective of development trends, CMM is gradually becoming the leading testing equipment in the machinery manufacturing industry, which will be increasingly used in the production line and become an integral part of the manufacturing system. No other measuring instrument has the flexibility and versatility of a coordinate measuring machine. The CMM can complete various complex measurements under computer control, exchange information with the machine tool, and complete the tasks of quality assurance and processing control. According to the test results, CAD and CAM software can be formed to realize reverse engineering.
