ENGINEERING TOOLS AND METHODS
• Importance of distinguishing between a feature and feature of size • The definition of feature of size from Y14.5 • Requirements and categories of a feature of size • Identifying and interpreting a complete, interrupted, partial, and bounded feature of size Applicable Drawing Standards • Determining on which standards an engineering drawing is based • Clarifying a drawing when no dimensioning standard is referenced • Reducing confusion on dimensioning standards Drawing Interpretation • Interpreting an engineering drawing • Drawing title block, revision column, general drawing notes • Fundamental rules that affect drawing interpretation • Surface coating and heat treat • Geometric controls and a valid datum system • Misconceptions on measuring parts that use the datum system • Controlling characteristics for each part feature • Proper uses for coordinate tolerancing • Specification / interpretation
• Describe uses, advantages, misconceptions, and common errors of the datum system • List nine common datum feature types • Describe advanced datum target concepts • Explain how to specify / interpret specialized datum feature applications • Describe modifier usage in tolerance of position applications • Describe the effects of simultaneous and separate requirements with tolerance of position • Explain composite position tolerancing and multiple single- segment position tolerancing • Interpret tolerance of position applications with a conical tolerance zone • Explain composite profile tolerancing and multiple single- This course is valuable for individuals who create or interpret engineering drawings, product and gage designers; process, product, and manufacturing engineers; supplier quality engineers/professionals; CMM operators; buyers/purchasers; checkers; inspectors; technicians; and sales engineers/ professionals.
