Enhancing Robot Precision with CNC

Release time:12-10-2023

A hospital in the UK tested a robot for performing delicate eye surgeries.    The research revealed that the robot was 10 times more accurate than a human surgeon.    The robot could execute movements with precision within one micron.


Today's robots can perform more intricate tasks than their predecessors.    Experts unanimously agree that future collaborative and service robots will be capable of completing complex tasks with greater accuracy than humans.


In the past seven decades, the field of robotics has undergone remarkable advancements, transforming robots into more powerful, efficient, responsive, flexible, and precise machines.


Precision has emerged as a critical factor for the future applications of robotics.


Technically, there is no robot or manufacturing process that achieves 100% accuracy;    there is always a certain margin of error.


The average positioning error of a robot determines its precision and the types of tasks it can perform.    Over time, this average error has sharply decreased, thanks to various technological improvements.



Factors affecting accuracy: Industrial robots & collaborative robots


One of the primary factors affecting the precision of industrial robots is the gearboxes within their joints.    Encoders and the rigidity of specific robot arms also influence robot accuracy, although these have become quite accurate or are easily improved upon.


While precision might not be as crucial for collaborative robots as it is for other forms of automation, collaborative robots now incorporate more sensors to ensure accurate perception of their environment, enhancing their precision.    These robots have sensors that inform them about the force they apply to a surface and even the type of part they are about to grasp.


CNC Machining

CNC Machining's Role in Enhancing Robot Precision


The relationship between precision CNC machining and robot accuracy is symbiotic.    CNC machining, exemplified by Boyang Hardware, plays a pivotal role in augmenting the precision of robots.    Here's how:


1. High-Precision Parts: CNC machining produces components with exceptional precision, down to microns.    These parts are vital in constructing robots with tight tolerances, ensuring that the joints and moving parts align perfectly.


2. Custom Components: CNC machining allows for the creation of custom parts tailored to the specific needs of a robot.    This customization enhances a robot's performance by optimizing its design for accuracy.


3. Material Consistency: CNC machining ensures consistency in material properties, essential for robot construction.    Uniform materials guarantee that the robot's components, such as arms and gears, perform predictably and with high accuracy.


4. Tolerance Control: CNC machining offers precise control over tolerances, which is crucial for maintaining the exact dimensions of robot components.    Even small variations can affect a robot's overall accuracy.


5. Repeatability: CNC machining guarantees the repeatability of parts production.    Robots require identical components to function accurately, and CNC machining ensures consistent results.


6. Advanced Materials: CNC machining can handle a wide range of materials, including advanced alloys and composites, allowing for the creation of robots with lightweight yet highly accurate components.


In conclusion, precision CNC machining, exemplified by Boyang Hardware, serves as the cornerstone of enhancing robot accuracy.


The ability to produce high-precision, custom components with tight tolerances and material consistency is pivotal in creating robots capable of performing tasks with unmatched precision.


As robots continue to evolve, CNC machining will remain a vital partner in pushing the boundaries of their accuracy and capabilities in both industrial and medical applications.
