Coordinate Measuring Machines (CMMs)
Coordinate Measuring Machines (CMMs) are a highly sophisticated precision dimensional metrology equipment used in a wide variety of manufacturing facilities for carrying out complex 3D measurements. Bridge-type CMMs are one of the most popular types of CMMs. These are constructed with a granite base, aluminium bridges, steel guideways, powered with air bearings and ceramic heads and steel encoders. The presence of dissimilar materials poses a major problem for precision metrology since the alignment accuracy can change with temperature variations.
Rapid-I introduced the Shop-Floor CMM to obviate this problem with an all-steel construction with materials of very close coefficient of thermal expansion. Such a system is extremely stable and robust in shop-floor environments and does not need controlled-temperature clean rooms and component soaking to do accurate measurements. The operator can directly take the component from the manufacturing line, and measure the component in real-time with CNC-enabled automatic inspection.
