LITERATURE SURVEY

The stakes for efficiency, precision, and productivity in today's fast industrial landscape have never been higher. Cut- throat competition has made the integration of the latest technology into manufacturing processes no longer a luxury but more of a necessity. A sorting, handling, and 3D CNC machining system integrated with colour sorting and simulated using software such as Factory IO is one of the state-of-the-art techniques. The material sorting and handling and machining system integrates sorting, handling, and machining perfectly within the operation of changing raw materials into finished products— very efficiently and with extreme precision.

The concept starts with the entry point of raw materials in the production chain. This is made easy by an emitter. Materials are moved across the production process in one sequence and uniform flow by a conveyor belt [1]. A colour- sorting mechanism forms the heart of the system, carrying high-resolution optical sensors and intelligent AI algorithms. These sensors categorize materials into predefined groups based on colour. This is the first stage of sorting; it is the most important one because here, materials are directed to their respective machining processes, and each item is going to follow the right work-flow[2].

After being sorted, the materials proceed to their respective machining centres. For example, raw materials of a certain colour can be directed to a drilling station where it can be accurately drilled to holes, while raw materials of another colour can be worked upon at the milling station where it would be shaped and surface-finished [3]. In this regard, the CNC system controls the machining processes for accuracy, repeatability, and consistency of the machining processes. The products are sorted and placed in their respective storage boxes for collection or shipment. The structured approach minimizes human involvement and, therefore, errors to the least, with every product meeting high industrial standard [4].The backbone of this automated solution is comprised of the integration of advanced technologies such as high- resolution optical sensors, AI algorithms, and CNC systems. The robotic plays a key role in picking and placing the raw materials in the CNC machine [5]. With the inclusion of AI, it can adapt to changes in material properties and sorting requirements; hence, highly versatile.

On the other hand, CNC machining provides precision and reliability in such operations as drilling, milling, and cutting. These machining operations constitute the backbone of industries in the likes of automotive, aerospace, and electronics, where accuracy is not something that can be compromised. It is this interplay of technologies that creates a system that does many things, but does them with precision and efficiency .The smooth integration of the colour sorting module with the machining module offers several advantages. Integration of sorting and machining in one set-up does not require separate equipment for the two processes. This saves valuable floor space throughout the entire production cycle and reduces the time taken to produce, but also lowers operational costs. What's more, streamlined work-flow maximizes productivity of the production cycle with turnaround times that are faster than usual.

The most significant advantage is waste reduction. With the preciseness of the system in sorting and machining, it brings maximum material utilization, which leads to waste reduction. This characteristic is vital in addressing environmental concerns in manufacturing. Further, flexibility allows scaling up and adjustments according to the varying production volumes and can be accommodated for both small-scale operations and industrial-scale productions [6]. Another key feature is its flexibility; it can work with materials as disparate as metals, plastics, and other composites. It's good for aerospace, automotive, electronics, and the manufacture of consumer goods—all those industries that require a level of precision and consistency in their products [7].

Besides, the 3D simulation software is more efficient: Factory IO, for instance. Potential problems in a production line can be identified and even corrected beforehand in order that everything flows seamlessly from design to production. An integrated colour sorting and CNC machining system pushes the boundaries of industrial automation further. It is a versatile, scalable, and highly efficient solution for modern challenges in manufacturing, combining the latest technology. This system sorts, machines, and arranges materials within a single work flow, thereby cutting down on operational costs significantly and providing high-quality output that current industries demand. As manufacturers strive to innovate, it is such systems that will lead the charge toward efficiency, sustainability, and innovation.
