CMM
A coordinate measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs, including mechanical, optical, laser, and white light. Depending on the machine, the probe position may be manually controlled by an operator or it may be computer controlled. CMMs typically specify a probe's position in terms of its displacement from a reference position in a three-dimensional Cartesian coordinate system (i.e., with XYZ axes). In addition to moving the probe along the X, Y, and Z axes, many machines also allow the probe angle to be controlled to allow measurement of surfaces that would otherwise be unreachable.
March is a Fenland market town and civil parish in the Isle of Ely area of Cambridgeshire, England. It was the county town of the Isle of Ely which was a separate administrative county from 1889 to 1965. It is now the administrative centre of Fenland District Council.
The town grew by becoming an important railway centre. Like many Fenland towns, March was once an island surrounded by marshes. It occupied the second largest "island" in the Great Level. As the land drained, the town grew and prospered as a trading and religious centre. It was also a minor port before, in more recent times, a market town and an administrative and railway centre. March is situated on the banks of the navigable old course of the River Nene, today mainly used by pleasure boats.
