Modern manufacturing systems are being designed from the ground up to be as precise as possible. It is this high degree of precision which makes it possible for companies to make high quality products on a regular and repeatable basis. Unlike standard metrology services, the 3D metrology services are able to measure length, width and height of the product, even when the product shape is uneven or irregular. By working in three dimensions and thanks to the ability to collect data on multiple geometric surface points, the measurements are much more accurate than any conventional metrology system. With the emergence of 3D surface metrology, high precision engineering and production is now possible with a much lesser rejection rate.
Uses of 3D metrology
As of now there are a number of uses of 3D metrology services in the real world. Most experts recommend that when you are starting the planning work of any kind of manufacturing process or production line. The most common application is to measure a specific feature of a specific product. Specific measurements need to be accounted for as they will have a very big role in the overall manufacturing process.
- Quality control and inspection: Ensure that manufactured parts meet specified tolerances and dimensions, and to identify any defects or deviations from the desired specifications.
- Reverse engineering: Create digital models of existing parts or products, allowing them to be reproduced or redesigned.
- Product development and prototyping: Verify the design of a new product or prototype, and to identify any issues or areas for improvement.
- Surface analysis: Analyze the surface characteristics of an object, such as roughness, contour, or profile.
- Dimensional analysis: Measure the physical dimensions of an object, such as length, width, and height.
- Alignment and calibration: Ensure that machinery or equipment is properly aligned and calibrated, and to identify any misalignments or errors.
- Quality assurance: Ensure that products meet the required quality standards and specifications.
- Failure analysis: Identify the cause of a failure or malfunction in a product or component, and to determine the necessary repairs or modifications.
Different kinds of measurement in 3D metrology services:
In 3D metrology, measurements are taken using specialized instruments and techniques to accurately and precisely determine the physical dimensions and characteristics of an object or surface in three dimensions. Some common measurements that can be taken using 3D metrology techniques include:
- Length Width and Height: These are measurements of the distance between two points on an object or surface, typically taken with a caliper or micrometer.
- Surface roughness: This is a measurement of the texture or finish of a surface, typically taken with a profilometer or surface roughness tester. These are some of the key parameters in 3D surface metrology
- Roundness: This is a measurement of the degree to which an object is circular or cylindrical in shape, typically taken with a roundness tester or coordinate measuring machine (CMM).
- Straightness: This is a measurement of the degree to which an object is straight or aligned along a particular axis, typically taken with a straightness tester or CMM.
- Tolerance: This is a measurement of the allowable deviation from a specified dimension or shape, typically taken with a CMM.
- Angular deviation: This is a measurement of the deviation from a specified angle, typically taken with a CMM or angle gauge.
- Form error: This is a measurement of the deviation from a specified form or shape, typically taken with a CMM or form tester.
- Flatness: This is a measurement of the degree to which a surface is flat or level, typically taken with a surface plate or CMM.
These are just a few examples of the types of measurements that can be taken using 3D metrology techniques. There are many other measurements that can be taken depending on the specific application and the requirements of the measurement.
