The latest developments in modern industrial measurement technology (4)

Control technology for controlling processes

Renishaw of the UK exhibited the newly developed NCI non-contact tool measurement system, which is mainly used for tool adjustment and operational monitoring on machine tools. The system uses a visible laser to facilitate random measurement of the tool position, which can shorten the positioning time and prevent processing errors caused by improper tools, so that the processing efficiency and processing quality are further improved.

Japan's Mitutoyo exhibited the newly developed Measur Link series, a measurement data network system that can aggregate and analyze the product quality data obtained in the measurement process in real time. The production line and management department use the data provided by the system to carry out the data. Quality Control. Mitutoyo has developed a series of related software for users to choose. For example, there is a process management program applied by the measurement department, which can send the measurement data acquired by various measuring instruments to the microcomputer terminal, and draw it into a management chart or a schematic diagram, which can be displayed in real time, so as to facilitate early detection of abnormal phenomena, which can be effective. Prevent the occurrence of poor processing.

With the rapid development of information technology, many enterprises have adopted a large number of microcomputers and constantly improve the internal network system. Therefore, it is one of the technical research directions that companies need to continuously strive for in the future by using the monitoring system that comprehensively displays the production site conditions, making full use of information resources, and closely monitoring the processing quality.

Strive to reduce measurement costs

For a long time, most of the measurement and inspection work requires setting a constant temperature room to improve the reliability of measurement; the narrower the adjustment range of the temperature of the constant temperature room, the higher the maintenance control cost. Therefore, users want to purchase a measuring instrument that can fully perform its performance over a wide temperature range to reduce the cost of measurement.

Mitutoyo exhibited a newly developed flexible measuring machine QM-Measure, a simplified model of a benchtop CMM that can be used in production sites for inspections. The machine combines the functions of various metering tools to achieve long-term reduction in measurement costs. The machine is equipped with a temperature compensation function and can be used at a temperature of 15 to 30 °C.

The PRISMO measuring machine jointly developed by Zeiss and Tokyo Precision Co., Ltd. is also a CNC coordinate measuring machine for production sites, and the temperature condition for measuring accuracy is 16 to 30 °C. The measuring error of this measuring machine is E=20+L/300μm, and the measuring error is R=1.8μm, which is a high-precision measuring machine.

Although the above-mentioned measuring machines are used in different forms, they can be moved from the constant temperature chamber where the temperature must be strictly controlled to the production site for measurement, and the measurement accuracy can be effectively ensured. This has important pioneering significance in the precision measurement industry. And it is also very beneficial to users.
