With the increasing demands of modern manufacturing enterprises for manufacturing efficiency and workpiece quality, it is required to achieve on-site measurement of processed workpieces in the manufacturing workshop, complete on-site dimension measurement and verification of various fixtures and molds, and monitor the assembly status in real time. Through this method, it is possible to provide real-time feedback on the quality of assembly and processing, and provide a basis for adjusting the production process and quality control.

The traditional method of handing over tolerance and accuracy verification to the metrology department after processing is no longer suitable, and requires measurement equipment to work on site in the workshop. Generally, efforts and adjustments need to be made in two directions.

One is the ability to overcome the impact of workshop environment on precision measurement systems and adapt to the high efficiency requirements of on-site production.

Unlike the measurement room, the production site will face environmental temperature conditions that cannot be strictly controlled like the measurement room, and there are also conditions such as vibration, dust, and oil pollution that have a serious impact on measurement accuracy. To meet the measurement needs in the workshop, the measurement system needs to be equipped with a temperature compensation system, which compensates for the impact of temperature changes on measurement accuracy through software and sensors. Simple is linear temperature compensation, which involves placing temperature sensors at both ends of the measured workpiece and each machine axis to sense temperature changes and perform real-time compensation. Considering that the machine structure does not undergo a simple linear change with temperature, the concept of structural temperature compensation was introduced. For example, the CLIMA and ACTIV temperature compensation systems of the measurement system of Hexagon Metrology Industry Group achieve structural compensation under temperature conditions of 16-26 ° C and 15-35 ° C by placing multiple temperature sensors in the core position of the machine and utilizing the structural model analysis technology of the measuring machine itself, effectively ensuring system accuracy in complex temperature environments.

Some models, such as the Bravo, SIRIO, and ONE models from the Hexagon Metrology Industry Group, are specifically designed for measurement needs in the workshop. The machines have robust mechanisms, are suitable for complex environmental needs, have high efficiency and complete temperature compensation systems, and even the entire machine does not require compressed air. As long as there is a power socket, the system can ensure high-precision operation in the production site. These models are designed specifically for on-site use in the workshop, taking into account the special measurement needs of modern users.

In addition, considering the special environment of the workshop site and the requirements for measurement efficiency and integration with the production line, measurement manufacturers often help users solve these problems through system solutions or turnkey engineering. This includes the design of isolation systems, the establishment of temperature control rooms, manual and automatic loading and unloading systems, as well as various specialized and universal fixtures.
