9 Computer System: -
A computer system is typically connected to the CMM to run the measurement software, store measurementdata,
and interface with other systems for data analysis and reporting.
10 Enclosure or Housing: -
Some CMMs are housed within an enclosure or cabinet to protect the delicate internal components from environ-
mental factors like dust, temperature fluctuations, and vibrations.
• Machine Structure
• Probing System
• Controller
• Software

Machine Structure: -
CMMs are typically composed of a rigid structure with three or more axes of motion. This structure provides stability
and precision during measurements.

Probing System: -
The probing system is the heart of a CMM. It consists of a probe attached to a moving arm or a scanning head
that makes contact with the surface of the object to collect data points. Probes can be mechanical or optical, and
they come in various types suitable for different applications.

Controller: -
The controller is responsible for interpreting the measurements obtained by the probing system and converting
them into usable data. It manages the motion of the CMM’s axes and ensures accuracy and repeatability in mea-
surements.
Software: -
CMMs are equipped with specialized software that allows operators to program measurement routines, analyze
collected data, and generate reports. This software often includes powerful algorithms for geometric analysis and
statistical evaluation.
• Application of cmm: -
1 Quality Control and Inspection: -

CMMs are widely used for quality control purposes in manufacturing industries such as automotive, aerospace,
electronics, and medical devices. They ensure that components and products meet specified dimensional toler-
ances and quality standards.
