Core Tip:The 83rd meeting of ISO/TC39/SC2 International Organization for Standardization/Technical Committee on Machine Tools/Sub-Technical Committee on Inspection Conditions of Metal Cutting Machines was held in Salzburg Chamber of Commerce, Austria, from October
    The 83rd meeting of ISO/TC39/SC2 International Organization for Standardization/Technical Committee on Machine Tools/Sub-Technical Committee on Inspection Conditions of Metal Cutting Machines was held in Salzburg Chamber of Commerce, Austria, from October to 5, 2018.


    The meeting discussed the ISO/DIS 10791-7 "Machining Center Inspection Conditions Part 7: Precision of Finish Machining Specimens", which was proposed and revised by China. The "S-shaped" specimens were included in the appendix. Eventually, delegates agreed that ISO/DIS 10791-7 "Machining Center Inspection Conditions Part 7: Precision of Finished Specimens" entered the FDIS stage.

    Precision inspection and performance evaluation of five axis CNC machine tools are recognized worldwide problems. Promoted by the National Technical Committee for Standardization of Metal Cutting Machine Tools, the "S-shaped" specimens for the accuracy test of five-axis linkage machining machine tools were put forward and approved in 2012. It has been six years since the project was initiated. The "S-shaped" specimens have been questioned, revised and postponed until the meeting formally entered the FDIS stage, marking all the technologies proposed by China. The details have been discussed, and the machining accuracy inspection of the "S shape" specimen is about to enter the international standard sequence.

    Through participating in the international conference, the research and application achievements in the field of high-end CNC machine tools in China are displayed, which have been recognized by more and more foreign experts and established long-term communication channels. In the international organization for standardization, the rights and obligations of a P member have been fulfilled and exercised.
