Efficient Inspection on the Shop Floor

While sometimes a nuisance, inspecting machined parts is a critical function in the machine shop. Here are a few different looks at how to choose the most suitable inspection process for a given application.

Measurement and inspection in metalworking operations takes many forms. It can include any tools and devices that are used to verify that a part’s dimensions conform to the tolerances required by the part’s design. The list of such equipment includes anything from hand-held calipers and micrometers to gage blocks and plug gages to probing devices.

The variety of probe applications on machine tools, CMMs, comparative gages and portable arms makes correct selection of styli usage essential for efficient, reliable and accurate measurement. In “How to Choose and Use Styli,” we take a look at some key points that can be helpful in choosing the best measurement solution.

Often, the gaging and inspection function is a post-process operation that occurs after a batch or run of parts has been machined. Using this method, any out-of-spec dimensions are already produced and, depending on severity, may require reworking or scrapping all or some of the part run. Read “In-Machine Gaging Automates Part Inspection” to learn about a line of in-machine gages that provide an automated solution to post-process inspection.
