An optical coordinate measuring machine is a noncontact, high-precision measurement device that uses image processing to execute the precise and immediate 2D & 3D measurements of an object. Unlike traditional Coordinate Measuring Machines which mostly rely on manual examination,  Optical CMM relies on light-based sensors, cameras, or lasers, making them superior for the measurement of large as well as small or complex parts where contact might damage the surface of the object or hinder precise measurement.

Features of Optical coordinate measuring machine

• Non-Contact Measurement: An optical coordinate measuring machine operates on sensors, leasers, or probes to help avoid physical contact with the object.
• Highly accurate: Optical coordinate measuring machine provides submicron-level precision accuracy.
• 3D Scanning Ability: Optical coordinate measuring machine generates detailed 3D as well as 2D models by capturing multiple points across an object’s surface.
• Flexibility: Suitable for measuring soft, fragile, or hard-to-reach areas.

How Optical Coordinate Measuring Machine Works

Initialization by Setup:
Initially, the object is placed on the Calibrated machine’s surface for measurement. The software of the machine is configured to determine the object’s geometry & dimensions.
Non-Contact Probing:
Non-contact probing methods such as cameras and lasers are used in optical Optical coordinate measuring machines to the objects. In Optical coordinate measuring machines probe does not touch the object, which prevents damage and allows for precise measurement of the surfaces of the object.
Data Collection by software:
In Optical coordinate measuring machine probe is used to scan the surface of the object to collect the data points. These points are recorded in terms of their X, Y, and Z coordinates.
Point Cloud Generation:
The collected data points have a digital representation of the object surface which forms a point cloud. Every single point in this point cloud indicates a specific location on the object’s surface. Point cloud is mainly used to create a detailed map of the object under study.
Data Analysis:
The point cloud data helps in comparing the data with the design specification of the object, the software analyzes the data to detect any error in the object. This helps in identifying any manufacturing defect for quality standards.
Generate Report:
The results of these measurements have been presented by this machine in a comprehensive format. This report not only includes the results but also the deviations from design specifications and any detected errors. The report is represented with the help of graphs, charts, and 2D & 3D models to help understand the results more effortlessly.

Benefits of Optical Optical coordinate measuring machines:

Highly Precise:
Optical Coordinate Measuring Machines operate on advanced optical technology. This provides highly precise measurements, even in the nanometers. This type of precision is crucial in industries like aerospace, electronics, and automotive, where minor defects can create problems.

Non-Destructive Testing
The non-contact measurement capability of the Optical coordinate measuring machine is most critical. Unlink any traditional probes, this optical system uses cameras, lasers, and probes to measure the dimension of the object. This ensures that it’s a non-destructive process that does not touch the object in any way.

Versatility in measurement
Optical Coordinate Measuring Machines are highly versatile tools as they handle a wide variety of measurement tasks. Optical coordinate measuring machine can accurately measure objects of different shapes, materials, and sizes, ranging from tiny microelectronics to large industrial components.

Efficiency and Speed
One of the benefits of optical coordinate measuring machines is their ability to perform measurements quickly and efficiently. These machines are automated in nature which allows quick data processing and significantly reduces the time taken by machines for inspection. The speed not only improves productivity but also minimizes the time needed for manufacturing processes.
