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.

​Brigg (/'brɪg/) is a small market town in North Lincolnshire, England, with a population of 5,076 in 2,213 households (2001 UK census),[1] the population increasing to 5,626 at the 2011 census.[2] The town lies at the junction of the River Ancholme and east–west transport routes across northern Lincolnshire. As a formerly important local centre, the town's full name of Glanford Brigg[3] is reflected in the surrounding area and local government district of the same name. The town's urban area includes the neighbouring hamlet of Scawby Brook.
