The bridge type coordinate measuring machine has developed into the most precise method of measuring the demensions or shape of an object, whether in production, or in the laboratory.

New, low expansion materials have reduced the temperature sensitivity, so that the unit can be placed on the production floor. The sensitivity of the touch probes has improved in options of materials. Also, software programs can filter and improve the touch probe signal.

Having CMM capability be part of a machining process has been possible for the past 20 years on a single axis. This has expanded to multiple axes with a single probe in recent years.

To measure the accuracy of a lathe, the parts are round and the Y and Z axes are the same. Machining centers require three dimensional measuring and here the single arm probe in a gantry type motion can measure from three or more axes.

With five axis machining, the measuring capability has to follow.

CBG is looking at this measuring technology to add to our In Process Inspection products comparisons.
