Inspection and Measurement
Scanning For Process Improvements
A coordinate measuring machine with a constant-contact scanning probe makes it possible to get better, more complete information about workpiece features, especially contours. Two shops talk about how this information helps streamline their production processes.

How Accurate Is Your Machining Center?
Virtually every machine tool builder lists, as part of a machine's specification, accuracy and repeatability figures. What's generally not given is the method used to arrive at the figures. Though these methods are defined in linear positioning standards, not all builders use the same standards.

Gaging Distance Between Hole Centers
Many of the gaging applications we've considered over the years involve size inspection of a single feature, that is, the diameter of a hole, depth of a groove, height of a gage block, and so on. Many parts, however, contain multiple features that establish dimensional relationships between two or more other parts.

Conventional air gaging for measuring inside diameters is typically limited to a minimum size of about 0. 060 inch/1.

Called the Cordax Discovery, the fully automatic CMM is made to operate on the shop floor near CNC machine tools.
Read MoreFlexible Scanning Gage Is Designed For Shop Floor
While CMMs are extremely flexible as measuring systems go, and certainly provide the means to acquire a lot of dimensional data quickly, most shops have a hard time justifying more than one or two machines, even if they are designed for the shop floor. If Carl Zeiss IMT Corp. (Minneapolis, Minnesota) has its way, however, these same measurement capabilities will be found all over the shop, though not quite in the form of a conventional CMM.
