Enhancing Machine Tool Performance through Analysis and Implementation of an IoT-Based Energy Monitoring System

2024-04-24T11:45:16+00:00

Reducing the energy consumption of machine tools holds significant potential for enhancing the environmental performance of manufacturing systems. Given the mounting concerns regarding stringent environmental regulations, energy efficiency has emerged as a pivotal metric within the manufacturing industry. To address this imperative, the adoption of an Energy Monitoring System (EMS) framework is indispensable for pinpointing the energy usage of each machine tool on shop floors. This study introduces the implementation of an EMS tailored to CNC groove grinding machine tools at BOSCH Limited. The system, developed and engineered by Siemens, facilitates real-time data collection through energy meters, with the data being transmitted to a host computer via the RS485 serial communication protocol and continuously stored in a database. Consequently, energy consumption parameters are effectively tracked, archived, and visually represented in graphical formats. The accessibility of energy data is ensured through a connected Human-Machine Interface (HMI), offering a standard interface for monitoring energy consumption during specific operations and for particular part types. Additionally, the data is stored in a generic data server for ongoing monitoring and further computational analysis, facilitated by the Sentron software app. Moreover, the quantification of energy control functions for each machine is achieved through precise measurements obtained from signals processed by the Programmable Logic Controllers (PLCs). This capability enables the machines to dynamically adjust energy modes, thereby optimizing energy costs per part.

2024-01-18T06:18:28+00:00

This paper meticulously delves into the intricate flow characteristics exhibited by R134a refrigerant within an adiabatic capillary tube, employing a comprehensive and controlled experimental study. The fine cylinder, with a width of 0.00107m and a length of 3.5m, works with an unequivocally managed mass stream pace of 6.6 kgh^-1 giving an ideal climate to an intensive report. The pressure within the capillary tube displayed a distinctive pattern throughout the experiment, with measurements indicating 12.95 bar at 0.5m from the inlet, gradually decreasing to 4.68 bar at a distance of 3m from the entrance. Simultaneously, a conspicuous temperature drop from 35.8°C to 14.7°C was observed at the exit point, located 3.5m from the entry of the capillary tube. To enhance the credibility of the results, the experimental data concerning pressure drop within the tube underwent a meticulous comparative analysis which revealed a coherent trend. Furthermore, this paper contributes valuable insights by presenting experimental data on temperature drop, thereby significantly enriching the understanding of the dynamic behaviour of R134a refrigerant in adiabatic capillary tubes. These insightful findings bear implications for optimizing the efficiency of refrigeration systems.

A Review on the Composite Material-Based Mano Leaf Spring using ANSYS

2024-04-24T11:56:37+00:00

The suspension system is essential for providing protection and strength to the vehicle's structure. However, the suspension system is an area of concern for manufacturers in order to reduce the load of a car by decreasing its suspension weight. Suspension system weights account for 16-21% of unsprung weight. Furthermore, automotive suspension systems constantly evolve to protect against impact loads and avoid chassis deformation and damage. The leaf spring suspension systems are critical for lowering car weight and boosting fuel efficiency and ride comfort. The advantages of leaf springs are their simple and low-cost design. However, several leaf springs are utilized in cars depending on the vehicle's gross weight. The form of a leaf spring distinguishes it from other varieties. The quantity of leaves heaped together in the parabolic and conventional leaf springs is different. Automobile manufacturers want to replace steel leaf springs with composite leaf springs to reduce weight. This is a significant step toward energy conservation, lowering the vehicle's overall fuel consumption. Therefore, this study is intended to be a comprehensive resource for designing a leaf spring using various composites. Some writers utilize software such as CAITA, Creo, etc., to design leaf springs, and ANSYS software is used to analyze leaf springs. Numerous studies have suggested composite leaf springs are superior to ordinary mono and multi-steel leaf springs in terms of weight, stress, vibration, expanding strength, exhaustion life, and riding comfort.
