The manufacturing facilities are incomplete without metrology instruments, and now we have metrology systems that integrate automated CMMs and vision systems to reduce human error.  Venkat Srinivasan, COO of Trimaster Metrology LLP & Trimos India Pvt Ltd, shares that real-time measurement and feedback streamline production to provide consistent quality and faster inspections for modern manufacturing demands.

Metrology ensures that parts are made to the correct specifications. How are you using automation technology to enhance precision measurement in modern manufacturing?

We use automation technology to enhance precision measurement in metrology. Automation has revolutionised precision dimensional measurement in modern manufacturing. Automated CMMs and vision measuring systems have taken metrology ahead. These systems execute repetitive tasks with minimal human intervention, dramatically reducing the potential for human error and ensuring consistently accurate results. This strengthens the reliability of measurements and increases the output. The ability to perform faster inspections directly translates to improved production efficiency, allowing manufacturers to optimise processes and meet the demands of today’s fast-paced environment.

What are the latest advancements in online metrology and real-time quality control systems? What innovations has Trimaster Metrology proposed?

Online Metrology takes measurements directly to the point of production. By integrating precise measurement systems like our Trimos C4 instrument into the manufacturing line, users can reduce lead times and minimise errors in measurement processes. Our Trimos C4 CNC CMM does real-time feedback, instantly relaying data to the machining centre for accurate, online measurement and automated error correction. This seamless integration ensures higher efficiency, better quality control, and a more streamlined production process, thus making manufacturing more responsive than ever.

What challenges do you face in achieving micron-level accuracy, and how can they be addressed?

Environmental factors like temperature and vibrations, instrument limitations in calibration and resolution, material properties affecting measurements, human error, and contamination issues challenge achieving micron-level accuracy in metrology. We address these issues by strongly investing in controlled environments, high precision , and quality instruments with automated systems. We establish robust procedures, utilise advanced software, and maintain rigorous calibration and test schedules. Continuous improvements give us optimum performance and reduce errors.

How do metrology solutions contribute to reducing waste and improving manufacturing?

Our solutions drive sustainability in various industries. We deliver precise instruments according to the user’s requirements and also reduce inspection time. We also promote reuse through refurbished instruments. Regular servicing and calibrating instruments provide accurate measurements, optimise instrument usage, and decrease energy consumption through process enhancements, ultimately extending product lifespans. This focus on preventing rework and efficient resource allocation makes our metrology products a key contributor to a more sustainable and environmentally responsible manufacturing process.

What are some of the latest trends in portable and handheld metrology solutions, and how are they benefiting shop floor applications?

The latest trends in portable and handheld metrology solutions are revolutionising shop floor applications by offering greater flexibility, speed, and accuracy. Our 3D portable arms and height gauges empower manufacturers to perform on-site inspections quickly and accurately on the shop floor, thus streamlining workflows, reducing downtime, and enhancing real-time quality control.

Portable CMMs and handheld instruments, such as 3D portable arms and Trimos C4 CNC CMM, are incorporated into automated measurement routines. They can reduce operator dependency and minimise human error, speeding up inspection processes and ensuring consistent results.

Wireless data transfer and remote-control capabilities, like those in our Trimos height gauges, allow seamless integration with existing manufacturing systems. This facilitates real-time data sharing and analysis, allowing for immediate process adjustments.

Lighter, more compact designs and improved ergonomics make handheld devices easy to use in confined spaces and for extended periods, enhancing operator comfort and productivity.

What is the next big leap in industrial metrology that will transform manufacturing in the next five years?

Looking ahead, the next five years will witness a transformation in dimensional metrology with AI and advanced sensor technology.  Specifically, the widespread adoption of AI-powered, real-time, in-process measurement will be pivotal. The manufacturing lines will have dimensional metrology as an integral production process.  Sensors embedded within the instruments will continuously monitor dimensions, and AI algorithms will analyse this data in real-time. This will help systems to detect even minute deviations from specifications as they occur. The result will be self-correcting manufacturing lines that operate with unprecedented precision and efficiency. This will improve product quality and reduce costs while providing complex and innovative products.
