Scope

Main technical content: This standard specifies the terms and definitions of CNC vertical turning-milling composite machining centers, accuracy inspection requirements, and methods and steps for geometric accuracy and working accuracy inspections. Based on a comprehensive collection of relevant standards, and taking GB/T 17421.1-2023, "General Rules for Machine Tool Inspection - Part 1: Geometric Accuracy of Machine Tools under No-Load or Quasi-Static Conditions", as the core, this study conducted accuracy inspections of CNC vertical turning-milling composite machining centers and developed this standard. The main technical content of this standard includes: 1) Clarifying the terms and definitions of CNC vertical turning-milling composite machining centers. 2) Specifying general requirements for accuracy inspection, including measurement units, reference standards, inspection temperature, inspection sequence, and tools. 3) Defining the methods and steps for geometric accuracy inspections of CNC vertical turning-milling composite machining centers. This includes machine leveling before accuracy inspection, runout and chatter at the spindle end, the verticality and parallelism of the tool holder, the coincidence, verticality, and repeatability of the tool turret components with the spindle axis, as well as the positioning accuracy and repeatability of the X, Y, and Z axes. 4) Specifying the methods and steps for working accuracy inspections of CNC vertical turning-milling composite machining centers. This includes inspecting cylindrical workpieces, the flatness of the end face perpendicular to the spindle axis, and the parallelism of the opposite side plane perpendicular to the spindle axis.
