Abstract Indian sign language (ISL) is the indigenous language of the deaf and dumb community in INDIA. Sign language is a method of communication comprising simultaneous combination of hand shapes, orientation and movement of the hands, arms or body, and facial expressions. This report acknowledges us about the two hand sign language which is been widely used in India. I had designed a sign language translator device which works on the conversion of the sign gestures into text and speech. Therefore, it establishes a two-way communication between those who know sign language and those who don’t. Further the report deals with the technology and equipment used to observe movements of fingers using IR camera and then processing the image. The movement of hand was observed through the inertial measurement unit which gives the position with all 6 degrees of freedom. Then these movements were processed by a Beagle Bone black processor used for converting these signals from camera and IMU into respective text. Text was displayed on LCD/LED screen and using text to speech software a speech was out from a speaker. The study emphasizes on the description of anatomy of hand movements involving skeleton structure of hand, interphalangeal joints, and movement of fingers through muscles and connection of muscles to bone. The analysis of hand and design of translator, in which a standard human hand and a 12 year old child’s hand was been compared for the design of translator device including the extension of wrist, movements of fingers and size of hand. Translator was designed as to be used on any hand and camera was placed to observe any gesture movements.

Abstract Now-a-days, increasing the productivity and the quality of the machined parts are the main challenges of metal cutting industry during turning processes. Optimization methods in turning processes, considered being a vital role for continual improvement of output quality in product and processes include modelling of input-output and in process parameters relationship and determination of optimal cutting conditions. Main objective of our project is to study the process parameter, on tool wear (crater wear and flank wear), work piece temperature and metal removal rate. We will be using TAGUCHI OPTIMIZATION TECHNIQUE to analyze and optimize the process parameters and their dependence on each other. The tool to be used is carbide, and three different work pieces (EN31, SS 202 STEEL AND OHNS) are going to be used.

Title “EFFECT OF WELDING PARAMETERS ON MECHANICAL PROPERTIES OF GMAW DISSIMILAR WELDMENTS”

Abstract Gas metal arc welding (GMAW) is a welding process in which an electric arc is generated between a consumable wire electrode and the workpiece metal(s). In this process, heat is produced which melts the workpiece and join them on solidification or on cooling. It is the most common industrial welding process, preferred for its versatility, speed and the relative ease of adapting the process to robotic automation. Gas metal arc welding was originally developed for aluminium and non-ferrous metals but now it can be used for steels as it provides faster welding time compared to other welding processes. The design matrix will be prepared based on the number of process variables which will be chosen after conducting the literature review. The analytical models will be developed by regression analysis technique and the adequacy of parameters will be checked using the ANOVA method. Further the experimental set up will be prepared whose output results will be analyzed by comparing them with the analytical results. The developed models will be used to predict and indicate the important mechanical properties and the weld quality by selecting the appropriate process variables. The project aims at the complete analysis of the welded joints produces by gas metal arc welding and to also investigate the potential of controlling the various process parameters to obtain optimum results. The effect of various process parameters will be analyzed and further interpretation will be carried out on the mechanical properties of the weld.

Title “TO OPTIMIZE THE EFFECTS OF PROCESS PARAMETERS OF WEDM ON HIGH CARBON STEEL”
Supervisor Rana Ramakant (Lecturer, MAE Department)
Submission Date May 2014

Abstract Conventional machining operations tend to reach their limitations as newer materials are developed as very faster rate. In recent years, the technology of Wire Electrical Discharge Machining (WEDM) process has significantly improved to meet the latest requirement in the industry. WEDM process, with a thin wire as an electrode, transforms electrical energy to thermal energy which melts and removes the materials. With this process, high hardness materials like heat treated steel, super alloys, composites, etc. Material is eroded from the workpiece by a series of discrete sparks between the workpiece and the wire, separated by a thin film of dielectric fluid. High material removal rate and a very good surface finish cannot be easily achieved simultaneously. This is an age long problem and continuous efforts are being made by different researchers all over the world to meet such an objective. The objective of this project is in twofold. First part is to investigate the effect of various WEDM parameters on MRR, Surface Finish and Overcut and to arrive at an optimal setting. Second part is to compare the results obtained by two different tool wires materials. Experimentation is planned as per Taguchi’s L9 orthogonal array. Based on the literature survey the following four parameters are chosen at three different levels. These parameters are – TON, TOFF, Wire Tension and Wire Feed. The workpiece material for the experiment is EN31 and the two tool wires which are used in this experiment are – Brass wire and Zinc coated brass wire. Wire-EDM “SPRINTCUT ELPULS 40A DLX” machine has been used throughout the machining of workpiece.
