Drawing and Drafting / Dimensioning and Tolerancing
The Drawing Requirements Manual (DRM) is a valuable reference for engineers, designers, drafters, machinists and quality control inspectors who need to understand drawing requirements and interpretations. It is the authoritative source for preparing engineering drawings for industry, while meeting the requirements of the Department of Defense (DoD).
Your company cannot afford to make mistakes in interpreting engineering designs throughout the manufacturing process. That's why the ASME Y14 series is so important an investment to make. Important changes in the latest ASME Y14.5 - 2009 address concept of feature of size; datum references and degrees of freedom; composite position tolerances; surface boundaries and axis methods of interpretation; profile tolerances; and symbology and modifiers tools. Additionally, the subject matter has been restructured for better readability, with profile, orientation and form now in separate sections, and material within sections reorganized.
