A coordinate measuring machine (CMM) is a device used to measure the physical geometric properties of an object. These machines can be manually controlled by an operator or they can be controlled by a computer. Measurements are defined by a probe attached to the third moving shaft of this machine.
The Capability Maturity Model (CMM) is a method for developing and perfecting an organization’s software development process. ISO 9000 standards establish an effective quality system for the manufacturing and service industries. ISO 9001 is specifically about software development and maintenance.
The CMM also allows you to control the angle of the probe to allow measurement of complex surfaces that would otherwise be inaccessible. The most common use of a CMM is to test the accuracy of a manufactured part against its original design to ensure it meets stringent quality requirements.
A coordinate measuring machine (CMM) works similar to your finger when it draws the map coordinates of its three axes from the machine’s coordinate system. Instead of a finger, the CMM uses a probe to measure points on a part. Each point on the part is unique to the machine coordinate system.

There are five levels of CMMs:
There are four basic types of coordinate measuring machines: bridge, arm, portal and horizontal arm. Each offers unique advantages depending on the components to be measured. Bridge.
Put simply, a CMM machine is a device used to measure the physical geometric properties of an object. This procedure uses a probe mounted on the third moving axis of the CMM machine, which allows to define the dimensions of the piece under examination.
Regarding the degree of maturity, the process areas are divided into the following five categories:
Capability Maturity Model Integration (CMMI) is a training and assessment program to improve the process level. CMMI defines the following levels of maturity for the processes: Initial, Managed, Defined, Quantitative Managed and Optimization.
KMG stands for Cubic Meters Per Minute
Today the price range of MMTs ranges from around 30,000 to over US $ 1 million, depending on the manufacturer’s specifications. Similarly, the cost of various probe / sensor configurations ranges from several thousand dollars to several tens of thousands of dollars.
The flatness of optically planar surfaces is measured using CMM pen techniques. The pen can be used or programmed to make specific and precise measurements along the surface of the object and automatically compare the data to generate a report on the flatness of the object.
A vernier with a thickness can be at least 0.1mm, while a micrometer can be at least 0.01mm. The smallest counting error occurs with both systematic and random errors. Instruments with greater precision can reduce the smallest counting error.
In a CMM system, several discrete points on the surface of the element are measured. The form error of the function (ε) is then determined by minimizing the maximum error value of the sampled points with respect to the position and orientation of the ideal form.
(CMM) is a tool for measuring the physical-geometric properties of an object and can be controlled manually by an operator or by a computer. Global Performance comes standard with a touch sensitive probe, temperature compensation and advanced software with CAD functions.
A maturity model is a tool that helps people assess the current effectiveness of a person or group and determine the skills they need to learn to improve their performance.
