Calipers: Ideal For Measurement On The Go

Although it has been around for a long time, the caliper is still an extremely versatile and useful tool for making a range of distance measurements (both ODs and IDs). While micrometers are more accurate, they have a limited measurement range (typ...


Machine Compensation

Ever since electronics first made their way onto machine tools, machine builders and users have tried to achieve some level of "automatic" process control. Certain causes of dimensional variation in machined parts—tool wear, for instance—occur grad...


Perfect Gaging In An Imperfect World

It is certainly not news that, more and more, gages are being forced out onto the shop floor. Tight-tolerance measurements that were once performed in a semi-clean room by a trained inspection technician are now being done right next to the machine...


Gaging Countersunk And Chamfered Holes

While countersunk and chamfered holes are similar in appearance, functionally they are quite different. Consequently, different gages exist to serve these different functional requirements.


Never Forget The Basics

We spend a lot of time in this column discussing sophisticated gages and out-of-the-ordinary applications—so much so, that perhaps we've lately been neglecting the basics. After all, the fanciest electronics, computers and software won't deliver ac...


Electronic Height Gages

We've looked at "basic" comparative height gages, which are used for layout tasks and other surface plate measurements. Related to these are instruments known as electronic height gages.


Inspecting Tapers, Part 2: Toolholder Gaging

A few months ago, we discussed the calibration of conical taper masters, which are used to master taper gages. Now let's look at the parts those gages are used to inspect—toolholders.


Assessing Gage Stability

Gage stability implies different things in different contexts. If taken literally, it may refer to whether there is something loose on the gage, or some other gage problem occurs randomly, to cause two identical trials to produce different results....


Gaging 'Relational' Dimesions

Specifications often require inspection of dimensional relationships between two features, or between two dimensions on the same feature. Compared to single-dimension specifications (such as diameter), these "relational" specifications can be chall...


When Indicators Go Both Ways

Measuring and gaging are two fairly distinct forms of dimensional inspection. Measuring is a direct-reading process, in which the instrument incorporates a continuous scale of units, against which the part is compared directly.
