What is Defect Detection?
Let’s proceed by understanding ‘What is a Defect?’
As per Wikipedia – ‘A physical, a functional or aesthetic attribute which exhibits the product has failed to meet the expected standards and specifications.’
A simple and pretty straight forward explanation about the defect. A defect is further categorised into three main categories:
Deriving from the above pointers, we can understand that flaws are spotted through the Defect Detection process before a product is dispatched to market or for consumption.
Importance of Defect detection
Defect detection and quality control are essential for any production process. Timely defect detection can save an organisation from losses and expensive re-work. This is especially important for products that are very expensive to produce or are very delicate . In the face of it, it seems to be a reasonably simple exercise that can be conducted by an experienced professional. Manual Defect Detection is a time taking process and follows the sampling approach. Additionally, it is prone to introducing subjectivity.
But today, with the increased levels of automation across various industry sectors, there is a pertinent need for automated Defect detection. For every business to stay relevant in the market place, it has to walk the thin line between quality and quantity, i.e., the ability to satisfy market demands by maintaining excellent quality for each product produced.
Which sectors will gain the most from defect detection?
Timely defect detection of manufactured products is crucial. A production process, especially those who are running through various stages, requires run time detection of flaws. This way, timely action, and repairs can be executed.
A single component/ piece on a satellite is a coming together of parts produced by various producers. It is a complex production process. The likelihood of surface defects is high. The Challenger space shuttle disaster of 1986 can be a haunting reference to the importance of surface defect detection.
In the age of chemical and biological warfare, even a non-visible hole in military equipment can have disastrous impacts. Also, military equipment has to maintain its integrity in high pressures. Defect detection plays a crucial role here.
It is obvious who so ever wishes to buy a brand new car, would not like to have any scratches, cracks on its surface. It has to be perfect. A defective surface can have a drastic impact on sales figures.
Diamond is a girl’s best friend- but on the other side – a defective diamond is worth a piece of coal. The smooth unspoiled surface is one of the selling points of jewelry items.
A most common example is a punctured syringe. Imagine the kind of impact it might have in an emergency. Likewise, in the case of radiology equipment, radiation leak can cause a catastrophe.
The above sectors are product sectors, but surface detection is also useful in various services sectors like Supply Chain Management, e-Commerce, etc.
Specific advantages might vary per sector, but the common benefits of Defect detection across industries are:
Delivering high-quality defect-free products helps achieve higher customer satisfaction and better business opportunities.
Higher quality permits the setting of higher standards. Production processes can be further fine-tuned as per the standards.
Good quality products tend to market themselves better. The reputation of ‘Good Quality’ spreads faster through word of mouth.
With proper defect detection processes in place, a manufacturer can make an unforgettable space in the minds of his end-user.
Griffyn Robotech, an organisation based in Pune, India – has made headways in the field of Surface defect detection by developing two innovative products, namely ‘DEEPSIGHT’ and ‘OPTIVITY.’
DEEPSIGHT is a cosmetic grading machine created for mobile phones and tablets. It has proven its capabilities in the grading of electronic products in forward and reverse logistics.
OPTIVITY leverages advanced image processing capabilities and machine learning to detect surface anomalies invisible to the human eye.
Both these products are making their mark felt across various sectors with quite a lot of positive reviews and recommendations.
