19 September 2023


Carry out quality control in your manufacturing plant through CMM Measuring by Aero Spec Engineering. Discover its working principles and associated advantages.

Coordinate-measuring machine or CMM measuring is a highly advanced technology that allows for precise and accurate measurement of complex geometric features. It can be utilised in assessing the dimensional characteristics of a wide range of objects, covering small components to large structures. Generally, this advanced technology works based on the principles of coordinate geometry, which is the study of geometric objects using a coordinate system.

How CMM Measuring is Conducted

The machine used for CMM measuring maximises a combination of motion control systems and high-precision encoders to precisely position the probe in 3D space. The probe is then directed to specific points on the object’s surface to collect data on the coordinates of each point. The data is captured by the CMM’s software, which analyses and processes the measurements. The processed data can, ultimately, give accurate dimensional information.

CMMs can utilise a wide range of probes depending on the application and object being measured. The most common types of probes are tactile probes and non-contact probes. Tactile probes physically contact the surface of the object, while the non-contact ones capture measurements without touching the object.

CMM Measuring and Quality Control

Given the importance of quality control in the manufacturing industry, more and more manufacturers take advantage of CMM measuring as a way to produce high-quality parts and products. Here are some advantages of CMM measuring in quality control.

• Highly Accurate: With CMMs’ sophisticated probing system and advanced software, they can easily measure parts and components with incredible precision, often reaching tolerances within micrometres. This level of accuracy is crucial in industries where even the slightest deviation can lead to product failure or performance issues.

• Comprehensive Measurement: CMM measuring offers comprehensive measurement capabilities that allow for the inspection of various dimensional aspects of a part or component. From simple length and width measurements to complex geometries and profiles, CMMs can capture a wide range of dimensional data, making them suitable for inspecting intricate parts found in the aerospace, automotive, and medical industries.

• Time Efficient: CMM measuring can significantly reduce the time required for quality control inspections. CMMs tend to automate the measurement process, enabling rapid and repeatable inspections. Their time efficiency allows manufacturers to streamline their production processes, reduce downtime, and improve overall productivity.

• Full Data Analysis and Reporting: The software integrated with CMMs allows for advanced statistical analysis, trend identification, and data visualisation. This data-driven approach allows manufacturers to gain insights into process variations, identify areas for improvement, and make data-based decisions to enhance product quality.

• Complex Geometry Inspection: CMMs excel at inspecting complex geometries that may be challenging or impossible to measure accurately with traditional tools. By using multiple axes of movement and advanced probing systems, CMMs can capture data points on curved surfaces, intricate features, and non-standard shapes.

CMM measuring is a powerful tool in quality control, offering high accuracy, comprehensive measurement capabilities, time efficiency, and data analysis. Manufacturers across various industries can benefit from the advanced technology and capabilities of CMMs to make sure their products meet stringent quality standards.
