What is CMM?
CMM(Coordinate Measuring Machine) is an advanced measurement machine works for measure complex and large component. CMM is a device for measuring the physical characteristics of an object. The machine is controlled by a computer or an operator.
CMM consists of 3-axis namely X-axis, Y-axis, Z-axis. Measurement is done by the prob attached to a third moving axis. This prob could be mechanical, optical, laser or white light.
So, the machine who takes reading in 6 DOF(Degree of freedom) known as CMM.

Components of CMM
The 3 main component of CMM are-
- Machine itself (includes its 3-axis)
- Probing System
- Controllers & Softwares
Working Principle of CMM
CMM record X, Y, Z coordinates of the object and generate point which analysis by regression algorithm. This points are collected by Prob via direct computer control.
Main Parts of CMM
- Air Bearing
- Scales & Encoders
- Prob system
- Servo motors
- Machine control system
This is Mitutoyo’s manual floating bridge type CMM coordinate measuring machines designed to achieve very high accuracy in a wide range of applications.The model type is CRYSTA-PLUS M is the intelligent alternative to the complex, cost-intensive measuring equipment with conventional multi-point measuring devices.
Pros of CMM
- Single Setup
- Improved Productivity
- Reduced Setup Time
Probs of CMM
CMM probes are available in three main forms:
- Touch-Trigger probes
- Displacement Measuring CMM probes
- Proximity or Non-contact Probes

Types of CMM
There are four basic types of stationary CMM:
- Horizontal Arm.
