Gears are the important element of a mechanical system, which are used for variation of speed and power, failure of even a single tooth of a gear will make the machine to stop. Hence our aim is to strengthen the gear which is a key element of gear box. At Dynatech Engineering. Co. Ltd. due to catastrophic failure of gear teeth, the problem of gear teeth deformation occurred. Dynatech Engineering Co. needed to suggest appropriate gear material by considering its strength, cost, hardenability and machinability, due to past history of gear teeth failures. The materials utilized for pinion and gear are EN24 and EN8 respectively. The material properties and costing of pinion and gear material were studied, and standard gear materials were identified from PSG Design Data Book. The material sorting is done on the basis of availability, cost and strength of the material. We studied different material selection methods like Weighted Point Method, TOPSIS, COPRAS, ELECTRA and VIKOR Method etc. From these methods Weighted Point Method (WPM) is selected for material selection and its result validated by TOPSIS Method and COPRAS Method. The material is selected by studying above method. On that material we did the finite element analysis and we also did analysis on currently used material in Dynatech Engineering co. The input parameter required for analysis provided by company such as module, teeth on pinion and gear, operating temperature and torque on which it is operating etc. The analysis is done by using the software ANSYS 15.0. From the result of it is concluded that the selected material have less deformation and stress during the operation at the top of the teeth as compare to the existing material.
Modelling and simulation of stepper feeder mechanism for punch press
(AIKTC, 2015-05) Shaikh, Rizwan; Sarfraz, Ahmed (11ME06); Gaonkar, Rajesh (11ME22); Shaikh, Maaz (11ME56); Ayub, Mohammed Ishaque (11ME13)
A common method of feeding the stock material into the press is bypassing it through a pair of feed rollers which apply friction to the material and rotate in a cooperative manner to feed the stock in to the punch press. By synchronizing the rotation of the feed rollers to the speed of the press,the stock material is fed in to the punch press at the proper rate.Stepping motors are widely used in robotics and in the numerical control of machine tools to perform high precision positioning operations.The principal object of this invention is to provide a strip stock feeding mechanism that is suitable for feeding any desired length of stock for each cycle and which may be very easily adjusted for various lengths of feed.It was found that cost of stepper feeder is quite less as compared to other types of feeder available in the market.

Small scale industries plays an important role in Indian economic. It has emerged as powerful tool in providing relatively larger employment next to agriculture. It contributes more than 50% of the industrial production in value addition terms and generate one third of the export revenue. Global markets are continuously changing and demanding product of high quality and low cost. Such products can be produced using lean manufacturing, a management philosophy that aimed to reduce all types of wastes at all levels of product manufacturing so as to reduce product cost. 5S is a basic lean manufacturing tool for cleaning, sorting, organizing and providing necessary groundwork for work place improvement. This report deals with the implementation of 5S methodology in the Otoklin filters Company, Ambernath, Maharashtra. Out of the available various lean manufacturing techniques, 5S offers good potential for required improvement. 5S is a systematic technique used by organizations comes from five Japanese words; Seiri (sort), Seiton (set in order), Seiso (shine), Seiketsu (standardize), and Shitsuke (sustain). This system helps to organize a workplace for efficiency and decrease wasting and optimize quality and productivity via monitoring an organized environment. It also provides useful visual evidences to obtain more firm results. There is a real need for empirical studies in field of new management systems and their impact on company‟s performance. As importance role of continuous improvement in today‟s organizations, and lack of sufficient evidence to show the positive impact of 5S on organizational performance, this paper aims to determine performance factors and characteristics in industrial organizations and identifying the effectiveness of 5S implementation on organizational performance as well. Surveying method is used and data collection is done by distributing questionnaire among five target organizations which have implemented 5S techniques. The target organizations are chosen from different industries and diverse field of work. The results of this research obtained from a comparative measurement of organizational performance before and after 5S implementation. The results show that 5S is an effective tool for improvement of organizational performance, regardless of organization type, size, its production or its service. Consequently, 5S techniques would strongly support the objectives of organization to achieve continuous improvement and higher performance.

(AIKTC, 2015-05) Rizvi, Zoya; Ansari, Armaan (11ME08); Dabir, Altamash (12ME82); Khan, Sufiyan (11ME33); Shaikh, Ijaz (11ME54)
As No. of Airlines has been formed, Competitiveness has been increased. All these Airlines use some of the methods for assembling the wheel of the Aircraft. This Assembly requires manpower and Human effort to a larger extent and this leads to problems for human beings like Back and neck problems. So we have found out a method to reduce man power by designing a fixture which could be rotated and aligned in any position (Automation).This also increases efficiency and saves time per assembly. A typical A-310 aircraft consists of 8 main wheels and 2 nose wheels. Currently 3 Service Engineers (S.E) are required to assemble the main wheel of the airbus. We hope to change the method of assembly of the wheel, so as to improve efficiency and to reduce the actual working time. As a result, we hope to change the current manual method of assembly of the wheel, so as to improve efficiency and to reduce the actual working time. As a result we hope to increase the total number of assemblies from the current capacity of 6 assemblies per shift to 12 assemblies per shift. Hence, as result a huge chunk of time will be saved in assembly and also manpower will be reduced.

Modeling , simulations are performed using modeling software i.e. SOLIDWORKS and analysis on ANSYS. The maximum deflection is determined by performing static analysis. Computed results will be then compared to analytical calculation, to check whether the location of maximum deflection agrees well with theoretical approximation. The chassis is designed such that it requires less material and as well as it is strong enough to withstand the various impacts on it. Strength and light weight were our basic consideration throughout the design of the chassis of the kart. Hence, AISI1018 was selected as an appropriate material for design which is a medium carbon steel with properties such as light weight, high tensile strength, high machinability, better weldability, etc. All the impacts and stresses were calculated manually by considering the severe working conditions and then the design was analysed in the analysis software. Step by step modifications in design were made as found necessary and as analysed on the software. After the complete analysis and the approval of design by inspecting it in all the modes of failure the design was finalized and was selected to fabricate which will not fail in any extreme criteria of stresses or load induced.

Plastic, although considered as one of the greatest inventions by virtue of its use in carrying things but has become a major element in polluting the environment. Plastic bags are known for their carcinogenic gas release after burning in air, for choking of sewage lines during monsoon season and the harmful effect on aquatic life. Government is promoting the use of paper bag to reduce plastic pollution. The project aims at designing a model of paper bag manufacturing unit, which would manufacture paper bags from A4 size educational sheets also commonly known as assignment papers (21.7 X 28.8 cm). The assignments which each student write during his academic year are used as raw material for our manufacturing unit. The paper bags are designed by taking into consideration it’s cost, load carrying capacity and aesthetics. These paper bags have been tested at standard conditions and were found to have enough strength to replace plastic bag of 20 micron (10 X 14 cm). This project is based on reuse of papers for manufacturing paper bags instead of using recycled papers. It also aims on switching traditional manual method of paper bag manufacturing to low cost semi-automated system in order to achieve the goal of mass production of paper bags through automation. The motive behind doing this project is to manufacture paper bag which are easily disposable, cause no harm to environment and replace the current trend of using plastic bags in India.
