T/WLJC 110-2022 The basic regulations for tolerance labeling in the 3D design of machine tool equipment products
Basic Information
Scope
Scope: This standard specifies the terms and definitions of tolerance annotation in the three-dimensional design drawings of machine tool equipment products, the basic provisions of dimensional tolerances and fit annotation, and the basic provisions of conical dimensions and tolerance annotation. It is applicable to the basic requirements of tolerance annotation when displaying or outputting three-dimensional drawings of machine tool equipment products in three-dimensional design view or axonometric view on the screen in the main model of three-dimensional design. Main technical content: 1. Scope 2. Normative reference documents 3. Terms and definitions 4. Basic provisions of dimensional tolerances and fit annotation: basic requirements, tolerance annotation on part drawings, additional symbol annotation for linear dimensional tolerances, fit annotation on assembly drawings, and annotation methods for angular tolerances 5. Basic provisions of conical dimensions and tolerance annotation: conical dimension annotation, dimensional annotation, taper annotation, conical tolerance annotation, limiting conditions, basic taper method, and tolerance taper method
