GB/T 16462.6-2017
Test conditions for numerically controlled turning machines and turning centers—Part 6: Accuracy of a finished test piece (English Version)

Scope: This part of GB/T16462 specifies a series of cutting inspections of standard test pieces under finishing conditions and the characteristics and dimensions of the test pieces themselves. The accuracy provided in this section is the minimum requirement for evaluating the cutting accuracy of machine tools. This part is applicable to the inspection of working accuracy of CNC lathes and turning centers (including CNC spindle machines, CNC vertical spindle machines and CNC inverted vertical spindle machines).
