CMM for Beginners

Also learn GD & T used in CMM software and datasheet: What is Alignment and Datum in CMM? With today’s CMM software, the CMM measures the workpiece’s datums establish the Part Coordinate System, and mathematically relates it to the Machine Coordinate System. The process of relating the two coordinate systems is called alignment. With a street map, […]

CMM machine Main Parts of CMM Air Bearing Under normal working pressure, the thickness of air space between air bearing and guide rail is fixed, which can ensure good repeatability of the coordinate measuring machine. If the pressure of air supply fluctuates, the change of the pre-tightening force of the air bearing will accordingly lead […]

A coordinate system is a lot like an elevation map where the combination of a letter along one edge of the map, a number along the other, and elevations shown throughout uniquely describes each location on the map. This letter/number/elevation combination is called a coordinate and represents a specific place relative to all others. A […]
