Meanwhile, articulatedarm machines are gradually branching out from their traditional end-use sectors (automotive, aerospace,military, and machine shops) to newer markets. These devices are preferred due to their light-weight and�exibility offered by multi-axis arms in measuring parameters that are beyond the reach of �xed CMMcon�gurations. The market has lately been witnessing an increasing demand for Portable CMM (PCMM),driven by the growing scope from the semiconductor and mechatronics industries, as well as industriesthat make use of digitizing and reverse engineering applications. Mid-range models constitute the bulk ofthe market.
