Inspecting a Prismatic Part

A number of instruments have the right amount of sensitivity required to inspect most prismatic parts, but a CMM is often the most accurate. Inspection starts by measuring each size dimension in two ways: the cross-sectional dimension, or actual local size, and, sometimes, the actual mating envelope (AME). Prismatic parts are also routinely inspected for certain geometric tolerances, including straightness, flatness, profile of a line, profile of a surface, angularity, perpendicularity, parallelism, and position. The ways in which a part must be inspected is based largely upon its shape, so proper inspection of a prismatic part requires an understanding of its basic dimensions and tolerances. After taking this class, users will be able to describe best practices for inspecting the complete layout of a prismatic part.


Course Objectives:

  • Describe prismatic part inspection
  • Explain how tolerance impacts how a feature is gaged
  • Describe the size dimensions used in prismatic part inspection
  • Describe how size dimensions are measured during prismatic part inspection
  • Explain how to inspect for straightness and profile of a line. Explain how to inspect for flatness and profile of a surface
  • Explain how to inspect a prismatic feature for perpendicularity. Explain how to inspect a prismatic feature for angularity. Explain how to inspect a prismatic feature for parallelism
  • Explain how to inspect a prismatic feature for position.


Recommended Background
