What is BS EN ISO 10791-2:2015?

BS EN ISO 10791-2:2015 is an international standard that specifies the testing and evaluation procedure for determining the geometric accuracy of machine tools. This standard focuses on the measurement and assessment of positioning and repeating positioning accuracy of workpieces, as well as the performance of linear axes, rotary axes, and spindle systems.

Importance of BS EN ISO 10791-2:2015

The importance of BS EN ISO 10791-2:2015 lies in its ability to ensure the quality and precision of machine tools used in various industries such as automotive, aerospace, and manufacturing. By implementing this standard, manufacturers can determine the accuracy of their machine tools to guarantee the reliability of their products. It also helps in identifying any deviations or inaccuracies, allowing for necessary adjustments and improvements to be made.

Testing and Evaluation Procedure

The testing and evaluation procedure outlined in BS EN ISO 10791-2:2015 involves a series of measurements and assessments. Firstly, the positioning accuracy of linear axes is examined using a laser interferometer or similar measuring device. This determines the ability of the machine tool's linear axes to position workpieces accurately. The repeatability of positioning is then evaluated by repeatedly measuring the same point and comparing the results.

Furthermore, the performance of rotary axes is evaluated through tests involving angle errors, backlash, and angular positioning accuracy. These tests assess the rotational movement capability of the machine tool. Additionally, the spindle system's performance is measured by evaluating its speed accuracy, axial runout, and radial runout.

Benefits and Applications

Implementing BS EN ISO 10791-2:2015 offers several benefits and applications. Firstly, it provides manufacturers with a comprehensive and standardized method for evaluating the accuracy of their machine tools. This, in turn, leads to improved quality control and enhanced product consistency. It also allows for benchmarking against industry standards, helping companies maintain a competitive edge.

Furthermore, this standard is applicable across various industries that utilize machine tools. Whether it's precision cutting, drilling, or milling, BS EN ISO 10791-2:2015 ensures optimal performance and accuracy. Aerospace and automotive industries can benefit from the high precision requirements, while manufacturing companies can achieve reliable and consistent results, boosting productivity and reducing material waste.
