Digital Twin Framework for Lathe Tool Condition Monitoring in Machining of Aluminium 5052

Abstract


 
 
 Digital Twin (DT) is a virtual representation of a product system that exhibits the properties and analyzes the system’s functions. The significant impact of DT extends to several fields, which increases productivity and reduces wastage. This article focuses on developing a Digital twin model of a Lathe machine for Tool Condition Monitoring (TCM). DT implementation in industries is challenging due to simulating online cutting forces and wear. Even though several pieces of research have been carried out in the prediction of tool conditions using machine learning, Artificial Neural network models, only a few pieces of research have been made in digital twins for TCM. This article provides the technique for implementing the DT model of a lathe tool. The feasibility of the DT Model framework is verified by a case study of the turning process with a CNC Lathe machine while machining of Aluminium 5052 workpiece using Titanium Nitride coated tool inserts. The sensor’s data are acquired and fed to the microcontroller for real-time data acquisition. The real-time dataset is processed in the DT model for monitoring and predicting the tool conditions. The tool wear classification using the DT model is achieved. Developing the Digital Twin model in machining increases productivity and assists in predictive maintenance.
 
 

New Techniques and Applications of Bioprocess inspired Manufacturing and Synthesis

“…Cattle horns are another source of wisdom because of their extraordinary ability to support weight and absorb force. In [3] described in detail the connection between the structural elements and the techniques of absorbing energy of different mammalian structural components as tusks, bones, horns, and teeth. The techniques of bio-inspired design were also presented by Murphy, Müller, and Jung [4] to develop new types of energy-absorbing composite materials.…”

Parametric study to investigate mechanical properties of welded dissimilar Al6063 and Al 7073 alloys through FSW process

“…The said novel welding technology showed the highest weld strength for welding aluminium alloys compared to other existing welding technologies [5]. After this invention, many dedicated researches on FSW were published to demonstrate the benefits of FSW for industrial applications [6]. Researchers demonstrated that process parameters (i.e., rational and transverse speed, force), probe shape, diameter, and materials' hardness significantly affect the weld strength.…”
