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, the most common being mechanical and laser sensors, though optical and white light sensors do exist.
The kilometre (SI symbol: km) is a unit of length in the metric system equal to 1 000 meters (10 3 m). To help compare different orders of magnitude , this section lists lengths between 1 kilometer and 10 kilometers (10 3 and 10 4 meters ).
A CMM provides a rapid method for inspecting absolute points, but geometric relationships, such as runout, parallelism, perpendicularity, etc., must be calculated rather than measured directly. By aligning an accurate spindle with an electronic test indicator with a geometric feature of interest, rather than using a non-scanning cartesian probe ...

Different lengths as in respect to the electromagnetic spectrum, measured by the metre and its derived scales.The microwave is in-between 1 meter to 1 millimeter.. A centimetre or centimeter (US/Philippine spelling), with SI symbol cm, is a unit of length in the International System of Units (SI) equal to one hundredth of a metre, centi being the SI prefix for a factor of 1 / 100 .

Just like humans, nutrition is important for our friends in the animal kingdom. Helping them grow and develop properly, the right diet can help our pets stay healthy.
Where the standard CMM uses a three dimensional Cartesian X, Y, Z system where each axis is orthogonal to the other, a Cylindrical Coordinate Measuring Machine omits the X or Y axis. The probe moves in only two axes (the vertical Z and either X or Y horizontal) and the rotating table positions the subject of inspection (a cylindrical part ...
