Manufacturing industries improve efficiency, output, and product quality using innovative robotic technologies. Industrial robots are integral in areas that require consistent, accurate work, like automotive, aerospace, and precision electronics manufacturing. Robot Absolute Accuracy is one of the most crucial aspects of robotic work.

Manufacturers demand precision when it comes to robotic work, in order to reduce errors and downtime, and to increase the rate of production. Robot Absolute Accuracy is key to achieving this. Coupled with a dependable Robot Guidance System, manufacturers can achieve the best level of automation and ensure work is of the highest quality.

Robot Absolute Accuracy Defined

Robot Absolute Accuracy is the measurement of how close a robot is able to position its tool center point, to a specified position in a program, with a specified allowance of deviation. In other words, it measures a robot's perceived ability to reach a given coordinate.

Numerous industrial robots are well designed with high repeatability. That is to say, they can arrive at the same point, time and time again. However, relative repeatability is not enough. For modern production applications, if a robot is off a target position, arriving at the same incorrect position repeatedly can still bring about production faults. Absolute accuracy is what ensures a robot can arrive at the correct position, and do so without repeated failures.

Robot Absolute Accuracy is important in industries like aeronautical engineering, where even the smallest error can lead to product failures and costly recalls.

Repeatability Versus Absolute Accuracy

Manufacturers brand repeatability and Robot Absolute Accuracy the same. While they are correlated, they are not parallel.

Repeatability defines how close a robot can return to a point after performing a task and returning multiple times. Robot Absolute Accuracy defines how close the robot can reach the exact programmed point for a specific task.

For instance, a robot can reach a distance of 2 millimeters to a target point, meaning it is more accurate for returning to the same point than it is for reaching the target point. This can lead to a lot of problems in high-precision manufacturing.

This is why industries like aerospace, medical device manufacturing, and electronics manufacturing require both high repeatability and high absolute accuracy in robots.

The Importance of Robot Absolute Accuracy to Manufacturing

Improves Quality

One of the fundamental benefits of Robot Absolute Accuracy is that it improves the quality of the products manufactured. With a lot of precision in robotic position, it decreases the errors of misalignment during assembly, welding, and accuracy.

Manufacturing industries can improve precision and thereby satisfy the strict quality criteria. Industries engaged in manufacturing products that are high-performance or that are safety-critical can benefit from this improvement.

Increased Speed of Production

With improvements in robotics position and accuracy, the number of manual adjust and corrections decreases, thus allowing industries to improve the speed of production cycles and the volume of output of quality products.

A well-calibrated Robot Guidance System allows robots to adapt to different operating conditions while maintaining improvements in accuracy. More output from the production process is achieved due to improvements in efficiency.

Less Waste and Rework

Manufacturing designs that contain defects leads to a lot of wastage of materials and products that should be rejected plus expensive processes to correct the manufacturing design. Inaccuracy in robotic position leads to errors in cutting, welding and assembly.

Robot Absolute Accuracy eliminates these issues by executing tasks accurately. Consequently, businesses save on material costs, operating costs, and increase profits.

Enhanced Synergy with Automated Systems

Today’s factories rely on higher automation levels with integrated systems based on machine vision, sensors, and digital controls for production. Perfect robotic positioning is fundamental for seamless connection of these systems.

Robot Guidance Systems increase the ability of robots to engage with the equipment around them and respond to changes in the manufacturing process. This flexibility in automation is an enhancement on the overall production efficiency.

Sectors That Utilize Robot Absolute Accuracy

The aerospace industry has an added advantage whereby the recent advances in Robot Guidance Systems assist in enhancing production as well as reducing the inaccuracies that are often present in the manufacturing process.

Manufacturing of Electronics

Manufacturing of electronics involves the handling of very small parts, once again, precision is a requirement. An example is the use of robots to manufacture printed circuit boards, the placement of micro components, and the manufacture of semiconductors.

Even the slightest deviation in position can either damage a part or result in a faulty product. Robot Absolute Accuracy is crucial to ensure the required level of precision and reliability of the products of electronics manufacturing.
