Scope

This document applies to the energy-saving design methods specified in GB/T 40808.1-2021 and the energy consumption measurement methods for machine tools and machine tool components defined in GB/T 40808.2-2025. Based on a reference scenario, this document introduces the environmental assessment of machine tools during their use phase and illustrates it with an example of metal cutting machine tools. This document defines a methodology for evaluating the operating status of machine tools based on a specific reference scenario, which is used for machine tool energy consumption assessment and integrates energy efficiency factors into machine tool design. This document elaborates on the content that needs to be measured in GB/T 40808.1-2021 and GB/T 40808.2-2025, and demonstrates how to evaluate the reference scenario of the "machining" phase of machine tools according to the provisions of GB/T 40808.1-2021. Appendix A provides a usage example of this document. It should be noted that the results obtained by using this document are influenced by the user's behavior during the use phase and the manufacturer's strategies. This document is not suitable for comparing machine tools with each other.
