What is a CMM?

What is a CMM? A CMM, or Coordinate Measuring Machine, is a type of industrial measurement equipment used to measure the precision of mechanical parts, components, or finished products. They utilize sensors and specialized control software to create a 3D model of the measured object and provide critical parameters such as dimensions, shape, and position. This aids in quality control and ensures the accuracy of parts and products, while also improving efficiency and reducing errors in the manufacturing process.

CMMs (Coordinate Measuring Machine) are referred to by various names, including: 3D measuring machines, 3D CMMs, coordinate measuring machines, and three-dimensional coordinate measuring machines,..

History of the 3D CMM

The Coordinate Measuring Machine (CMM) is a precision measurement tool that was developed during the 1950s and 1960s, a period when the emergence of digital computer technology offered significant potential for the advancement of measurement tools. Key milestones in the history of the CMM include:

1950-1960: The first prototypes of the 3D CMM were developed by leading information technology and measurement companies of the time, such as Brown & Sharpe in the USA, Ferranti in the UK, and DEA (Distribuzione Elettronica Applicata) in Italy. Initially, these CMMs were primarily used in military and aerospace applications, where high accuracy and reliability were crucial.
1960-1970: CMM technology continued to evolve with the integration of electronic sensors and precision probes, enabling measurements on complex and hard-to-reach surfaces.
1980: CMMs were further enhanced by incorporating optical and laser technologies, opening up new possibilities for non-contact measurement and height measurement.

Subsequently: With advancements in computer technology and the development of control software, CMMs have become more compact, user-friendly, and capable of higher precision. Coordinate measuring technology has been integrated with other technologies, such as optical, laser, and photoelectric technologies, improving the accuracy and reliability of CMMs.

Today, CMMs (Coordinate Measuring Machine) have become a crucial tool in the quality inspection process and in ensuring the precision of products across various industries.

Structure and Operating Principle of a CMM

Structure of a 3D CMM

The structure of a CMM (coordinate measuring machine) can vary depending on the type and manufacturer, ranging from compact handheld CMMs to large-scale machines used in heavy industrial applications. However, the basic structure of a CMM typically includes the following main components:

Frame: The frame holds the mechanical parts of the machine and forms the main structure of the CMM. It is usually made of metal, ensuring the stability and rigidity required for precise measurements.
Measuring Table: This is a flat surface, sometimes equipped with slots or clamps to hold the samples to be measured. The table can move along multiple axes (X, Y, and Z) to measure in different directions.
Probe: This device is mounted on the measuring table or an axis to measure points on the surface of the sample. The probe can be a touch probe, an optical probe, or a non-contact probe using technologies like spectroscopy, laser, or electromagnetism.
Measurement System: This electronic component includes sensors, controllers, and measuring software, allowing for the collection and processing of measurement data from the probe. The system is often integrated with specialized measurement software, enabling programmed measurements, calculation of measurement results, and display of measurement data on a computer screen.
Accessories: These include clamps, positioners, locating tools, dial indicators, and other accessories that help position and securely hold the sample on the measuring table.

Operating Principle of a CMM

A 3D CMM (coordinate measuring machine) operates by moving a measuring device along three axes, x-y-z, and uses sensors to record information about the position of the measuring device in three-dimensional space. The computer control software integrated with the measuring machine provides tools and functions to process data and display measurement results. Currently, some modern software can automatically generate measurement reports.

Classification of 3D CMMs

Various types of 3D CMMs (Coordinate Measuring Machine) are available in the market today, each with distinctive features suitable for different usage requirements. They can be classified based on the coordinate system used and the interaction between the probe and the surface of the part or product being measured.

Based on the coordinate system used:

Moving-bridge CMM: Includes both moving and fixed-bridge CMMs.
Cantilever CMM
L-shaped CMM
Optical CMM

Based on the interaction between the probe and the measured part or product:

Contact 3D CMM: Uses a physical probe that mechanically touches the surface of the part being measured.
Non-contact 3D CMM: Uses optical technology to accurately map details into a 3D model.

To determine which type of CMM is suitable for your production scale and product, let's explore more in the following content of this article with Yamaguchi.
