What does CMM mean?

The full form of CMM is Coordinate Measuring Machine. CMM works as an efficient device that helps to measure the lines of the physical object with the help of a probe. It locates the discrete points on the surface of the physical object. There are several kinds of probes used in a coordinate measuring machine. This includes white light, optical, mechanical, and laser.

Without the use of probes, the measuring of discrete points on the surface of the object is not possible. However, the position of the probe is changeable depending on the machine. Also, the position of the probe can be controlled or changeable by a computer or by an operator.

History of Coordinate Measuring Machine

In the early 60s, CMM made its first appearance in the market. In the 50s, the Ferranti Company in Scotland originally developed the CMM. However, the first developed CMM was 2-axis. The 2-axis was used for the 3D tracking device.

It also has a digital readout that is displayed with XYZ positions. Moreover, the Ferranti Company used the CMM for measuring its military products. However, the three-axis model made its first appearance in the 60s. CMMs are mainly used to assemble or test parts.

Component of Coordinate Measuring Machine

The main components of Coordinate Measuring Machine are:

• The main structure
• Probing system
• Reduction system
• Data collection

However, the main structure consists of three axes of motion.

Technical Facts of Coordinate Measuring Machine

The coordinate measuring machine consists of a total of three components. The three of them are primarily in the use of measuring the geometry of the physical object.

Let’s look at the three major components of a coordinate measuring machine:

• The primary structure of the coordinating measuring consists of three major axes of motion. However, the material used in making these axes has changed over the years. Previously, old methods like granite and steel were used in making these axes of CMM’s. Presently, the axes used in CMM’s are made of aluminum alloy. In some cases, ceramic is used to increase rigidity from the Z-axis. Therefore, today every CMM organization uses an aluminum alloy to build frames. Due to market requirements in a specific area, CMM manufacturers use granite to build frames. However, China and India are the two leading countries that build granite frames for coordinate measuring.
• It works best as a probing system.
• The CMM consists of a data collection and reduction system. This includes application software, machine controller, and desktop computer.

Benefits of Coordinate Measuring Machine

• The coordinate measuring machine is free-standing in nature
• The machines are highly portable
• The machine can be efficiently handheld
• It comes with an accuracy
• Reduction of human error
• It comes with great speed

Different Types of CMMs

Bridge CMM

The bridge CMM works with the three axes: X, Y, and Z. The axes are also placed in an orthogonal manner to each other in the Cartesian coordinate system. However, the probe’s position is monitor or regulated by a sensor from each axis. Therefore, it moves towards the object and detects discrete points on the surface of the physical object. This kind of point is referred to as a point cloud. Also, the CMM is divided into two sub-heads: moveable-bridge CMMs and moveable-table.

Pros of Bridge CMM

• It is highly efficient for measuring machine parts with high stability
• It shows an accurate result
• Ideal for small to medium component
• It is best used for scanning and probing

Cons of Bridge CMM

• It can be an expensive measuring component
• It gives a fixed measure volume
• Need efficient workers to run the device

Granty CMM

Granty CMM works similar to Bridge CMM. However, they come in a larger form. This is because it is used for lifting heavy or large parts. It is used on a regular basis in CMM. It should be placed mounted facing directly on the floor.

Pros of Granty CMM

• It is highly accurate in nature
• It is perfect for lifting heavy or larger parts
• Compared to the Bridge component, it is easier to load and unload components from Granty CMM

Cons of Granty CMM

• It gives a fixed measurement of volume
• It can be expensive like the Bridge CMM
