Articles related to inspection of engineering prints and interpretation of GD&T for inspection purposes
Some parts, such as those made of rubber or sheet metal, may fail inspection due to deformation from gravity if left in their "free state." This can be prevented by invoking a "restrained state."
Basic Dimensions are theoretically exact dimensions that define the ideal exact location and orientation of surfaces and features of size. A basic dimension is shown on a drawing as a dimension inside of a box,...
GD&T Basics has partnered with Mitutoyo to demonstrate how to set up and inspect a part using a CMM. In this video, we examine a part designed as a training aid by Mitutoyo, inspecting it...
This video is in response to a question that we received on our question line from Amber. Amber asked us if the tolerance value for circularity can be obtained by subtracting the upper limit of...
Ever wonder how surface finish is measured? For inspection, we use a device called a Profilometer. In this article, we will show you how profilometers work and highlight their advantages and limitations. What is a...
In this video, Brandon discusses basic dimensions and why they should not be recorded on an inspection report. What Are Basic Dimensions? Basic dimensions describe the theoretically exact location, orientation, size, or profile of a...
Do you know how dimensions and tolerances for complex parts are measured? Often, a coordinate measurement machine or CMM is used. In this article, we will look at different types of CMM’s and discuss how they work and when they are used. What is...
This video is in response to a question that we received on our question line from Brandon. The question is as follows: “I have profile tolerance on a flat surface of 0.2 mm with respect...
