Scope
This document defines the terminology of four-sided woodworking milling machines and their main components, specifies the geometric accuracy inspection and corresponding tolerances, and describes the corresponding testing methods.
This document is applicable to the accuracy inspection of general-purpose, ordinary-precision four-sided woodworking milling machines.
This document is not applicable to the operational tests of four-sided woodworking milling machines (such as vibration, abnormal noise, and creep of components), nor to the performance testing of machine tools (such as speed and feed rate).
