BS EN ISO 10791-2:2015 is a technical standard that provides guidelines for the evaluation of machine tools. It focuses on determining the geometric accuracy of machine tools through various tests and measurements. This standard was formulated by the British Standards Institute (BSI) in collaboration with the International Organization for Standardization (ISO).
Importance of BS EN ISO 10791-2:2015
Machine tool accuracy plays a crucial role in ensuring the quality and precision of manufactured products. Variations or errors in machine tool geometry can result in inferior product quality, increased production costs, and potential safety hazards. Therefore, it is vital to have standardized methods to evaluate and ensure the accuracy of machine tools.
BS EN ISO 10791-2:2015 provides a comprehensive framework for conducting geometric accuracy tests. It helps manufacturers, engineers, and quality control personnel assess deviations from the ideal geometry of machine tools, such as positioning accuracy, straightness, flatness, and rotational axes.
By following the guidelines set forth in this standard, companies can identify and rectify any inaccuracies in their machine tools, ensuring consistent product quality and optimal performance.
Testing Procedures and Criteria
The standard defines specific testing procedures to assess different aspects of machine tool accuracy. These include linear accuracy, angular accuracy, positioning accuracy, and backlash.
In the linear accuracy test, the machine tool's ability to move in a straight line is evaluated. This involves determining its deviation from a specified reference line using precision measuring equipment.
Angular accuracy testing focuses on assessing the machine tool's ability to maintain precise angles during operation, such as tilting or rotating movements. The standard specifies procedures for measuring angular deviations and setting acceptable tolerance limits.
Positioning accuracy, as defined by the standard, refers to the machine tool's ability to reach and maintain specified positions. It involves evaluating errors in linear positioning, point-to-point positioning, and simultaneous multi-axis positioning.
Backlash, another important aspect addressed by BS EN ISO 10791-2:2015, measures the clearance between moving parts in the machine tool's transmission system. Excessive backlash can result in diminished accuracy and repeatability. The standard outlines procedures for measuring and specifying acceptable backlash levels.
Compliance and Benefits
Adherence to BS EN ISO 10791-2:2015 enables companies to demonstrate their commitment to producing high-quality products. By conducting regular machine tool evaluations based on this standard, manufacturers can identify potential issues before they impact product quality or safety.
Compliance also offers a competitive advantage in industries where precision is paramount, such as aerospace, automotive, and medical devices. Certification or conformity with this standard enhances trust and confidence among customers and partners.
Moreover, by implementing the recommended practices outlined in BS EN ISO 10791-2:2015, manufacturers can improve overall production efficiency, reduce rework, and minimize scrap material. This leads to cost savings and enhanced productivity.
In conclusion, BS EN ISO 10791-2:2015 plays a crucial role in ensuring the accuracy and reliability of machine tools. Through standardized testing procedures and criteria, this technical standard helps manufacturers assess and rectify any deviations from ideal geometries. Complying with this standard not only ensures high-quality products but also provides competitive advantages in precision-driven industries. Embracing BS EN ISO 10791-2:2015 guidelines brings benefits such as improved efficiency, cost savings, and enhanced customer trust and satisfaction.
