The study is intended to highlight the importance of considering manufacturing processes and optical measurement methods in a numerical simulation when analyzing the damage behavior of metallic materials. To describe the damage behavior of the material in the process chain simulations, it is important to calibrate the parameters of damage model more accurately. These parameters are determined using experimental investigation of desired damage specimens. In this regard, a selected damage specimen manufactured by different cutting processes is first experimentally and then numerically investigated. It is shown that the manufacturing process and the optical measurement methods influence the stress state analyzed in the numerical simulation.</p> Mortaza Otroshi Gerson Meschut Aathavan Nesakumar Copyright (c) 2021 Journal of Manufacturing Engineering 2021-10-01 2021-10-01 16 3 070 076 IOT BASED SMART AGRICULTURE http://www.smenec.org/index.php/1/article/view/319 <p>Agriculture plays a vital role in the development of an agricultural country. Around 70% of people depend on farming in our country, and one-third of the nation's income comes from agriculture. Issues concerning agriculture have been continually impeding the improvement of the nation. The main answer for this issue is smart agriculture by modernizing the current customary strategies for farming. Henceforth the undertaking targets making agribusiness smart using computerization and IoT advances. The featuring highlights of this project incorporate smart GPSbased remote-controlled robots to perform errands like weeding, sensing moisture, animal and bird scaring, spraying, and so on. Also, it contains smart irrigation with savvy control and canny dynamic dependent on precise ongoing field information. Thirdly, smart warehouse management includes temperature support, humidity maintenance, and burglary discovery in the stockroom. Controlling of every one of these tasks will be through any far-off shrewd gadget or PC associated with the Web, and the tasks will be performed by interfacing sensors, Wi-Fi or ZigBee modules, camera and actuators with miniature regulator and raspberry pi</p> Agilesh R Asrath J Hariharasuthan N Santhosh K Sathya Priyan R Copyright (c) 2021 Journal of Manufacturing Engineering 2021-10-01 2021-10-01 16 3 077 081 IMPROVING SERVICE QUALITY OF DHABA WITH THE HELP OF QUEUING THEORY http://www.smenec.org/index.php/1/article/view/69 <p>Queuing theory is the mathematics of waiting lines. It is extremely useful in predicting and evaluating system performance. Queuing theory has been used for operations research, manufacturing and systems analysis The common problem arises in almost every famous dhaba is that they lose their customers due to a long wait on the line. Some dhaba provide extra chair for the customer to wait. But after waiting too long they leave. However, waiting chairs alone would not solve a problem when customers withdraw and go to the next dhaba. This causes a lot of loss to our dhaba. This shows a need of a numerical model for the restaurant management to understand the situation better. This paper aims to show that queuing theory satisfies the model when tested with a real-case scenario. Authors obtained the data from a “Gulshan Dhaba” in Hodal, Haryana. in order to derive the arrival rate, service rate, utilization rate, waiting time in queue and the probability of potential customers to balk. The collected data is analysed by using Little’s Theorem and M/M/1 queuing model. The arrival rate at “Gulshan Dhaba”, Hodal during its busiest period of the day is 2 customers per minute (cpm) while the service rate is 2.02 cpm during our study period. The average number of customers in the restaurant is 100 and the utilization period is 0.99.</p> Kajal Garg Komal Umesh Sharma Copyright (c) 2021 Journal of Manufacturing Engineering 2021-10-01 2021-10-01 16 3 082 086 DESIGN AND ANALYSIS OF THERMOPLASTIC POLYPROPYLENE ANKLE FOOT ORTHOSIS http://www.smenec.org/index.php/1/article/view/83 <p>Ankle-Foot-Orthoses (AFOs) are assistive devices used for neurological and physical disorders affecting the movement of the lower limbs. The needs of an increasingly young and active orthotic patient population have led to advancements in ankle foot orthosis (AFO) design and materials to enable higher function. &nbsp;Proper selection of material for manufacturing of AFO leads to greater increase in popularity to patients during walking providing better and compatible ankle foot orthotic device for patient specific. The purpose of this study is to develop design guide to find out the structural characteristics of polypropylene of AFO. In this research work, design and static analysis of a passive AFO to fit a human foot is presented. The static analysis was carried out for AFO made up of Polypropylene material with thicknesses 4 mm. Based on the results obtained from the static analysis. The results obtained from the static analysis showed that the polypropylene AFO was performing better results, generating less stress, deformation, and good factor of safety.</p> GAUTAM YADAV GAUTAM M L JAIN VIJAY GEHLOT Copyright (c) 2021 Journal of Manufacturing Engineering 2021-10-01 2021-10-01 16 3 087 091 TROUBLE SHOOTING OF RAW MATERIAL HANDLING IN BAGASSE PULPING http://www.smenec.org/index.php/1/article/view/58 <p class="5abscont">The agitator bearing and shaft bending due to foreign materials is reduced by using stuffing box in the agitator between bearing unit and impeller. The foreign materials in the bagasse wet washing are collected by using SS Pivot Needles/Bars in the wet washing system. The vibrations which cause damage (cracks) in the pump pipe line are reduced by using rubber bellow between the pump and delivery pipeline. The rubber bellow absorbs the vibration and deflections due to vibration which protects the pump and pipeline from damages. Earlier the foreign materials were struck up in the pump impeller. These foreign materials were removed by dismantling the entire pump set up. In the current work, the design of suction line was altered by introducing an inspection dummy. At the end of the suction line, through the new design the foreign materials were moved off from the pump impeller easily by removing the inspection dummy instead of dismantling the entire pump set up. Through the new design, the efficiency of the wet washing plant is increased upto 55%. Further, the downtime of wet washing plant also reduced and availability of equipment is increased.</p> SAKTHI VADIVEL K SIVARAJ C VIGNESHWARAN K Copyright (c) 2021 Journal of Manufacturing Engineering 2021-10-01 2021-10-01 16 3 092 107
