Burn – In: Burn-In is the application of thermal and electrical stress for the purposes of inducing the failure of marginal devices, those with inherent defects or defects arising from manufacturing aberrations which cause time and stress dependent failures.  It is a part of production flow in the backend test sequence, which exposes
Failure mode and effects analysis (FMEA) has long been used as a planning tool during the development of processes, products, and services. In developing the FMEA, the team identifies failure modes and actions that can reduce or eliminate the potential failure from occurring. Input is solicited from a broad group of experts across design, test, quality, product line, marketing, manufacturing, and the customer to ensure that potential failure modes are identified. The FMEA is then used during deployment of the product or service for troubleshooting and corrective action. The standard FMEA process evaluates failure modes for occurrence, severity, and detection (Chrysler Corp., Ford Motor Co., and General Motors Corp., 1995).
This chapter describes the overview of electrical discharge machining process (EDM) and presents outline of the research problem. 1.1 INTRODUCTION Electrical Discharge Machining (EDM) is widely used in manufacturing industries to make dies of complex cavities. In EDM, the material is removed primarily through the conversion of electrical energy into thermal energy through a series of discrete electrical sparks occurring between tool and work piece when both are immersed inside a dielectric medium and are separated by a small gap. The material is removed from the work piece by localized melting and even vaporization of material by high temperature spark. This causes many defects such as micro cracks, porosity, residual stress, in the white
CHAPTER 3 METHODOLOGY This chapter discusses and focusing the procedure used to investigate the surface roughness and microstructure during medium turning of Ti-6Al-4V ELI using different combinations of cutting parameter values under dry conditions. Experimental tests were carried out using uncoated carbide. 3.1 Experimental Equipments During the experiment was conducted, it involves the use of several testing equipments, cylindrical workpiece, and uncoated cutting tool. All these equipment will be discussed in the sub topic. 3.1.1 Testing equipment a. CNC lathe Haas ST-20 The machine involve in this experiment shown in Figure 3.1.
Methodology In this work we examined the cause of failure of gas turbine blade by SEM techniques and analysed the failure modes of turbine blade using modal analysis. But here we mainly focused over the modal analysis of gas turbine blade using experimental modal analysis (EMA) and computational modal analysis (CMA) and then correlating their results in order to identify the percentage variation of the EMA with CMA. Before working on the blade directly we first did with a cantilever beam of mild steel, then verifying the results of EMA and CMA for validation and then switching over turbine blade. In this way we will be able to rely on computational method for modal analysis of gas turbine blade and can say that this result is true upto maximum extent as per the applied boundary conditions. 1.4.1.
Then vertical drilling , horizontal drilling operation is carried out on the automatic machine. Then after the job is transport to the tapping machine. The problem which are face during this process are described below. The conventional method of the tapping operation was using the double cup and cone with crossed pulley. This was resulted into the duel pass of the component which was responsible for increment in cycle time, decrement in dimensional accuracy and increment in overall cost.
INTRODUCTION: Research in metal cutting was started with Cocquilhat in 1851 which measured the work required to remove a given volume of material in drilling. The attempt made by Time led to the explanation of formation of chips in 1870 and further research was made by Tresca in 1873. Later in 1881, Mallock suggested that the cutting process was the shearing of workpiece to form the chip and emphasized the importance of the effect of friction occurring on the cutting tool face as the chip was removed. Further, Taylor investigated the effect of tool material and cutting conditions on tool life during rough operations. Latest fundamental work has been carried out by Ernst and Merchant in 1941 dealing with the mechanics of metal cutting process.
Real-Time Estimation of Propagation of Cascade Failure Using Branching Process Priyanka Dey∗, Madhavi Parimi, S.R Wagh Electrical Engineering Dept Veermata Jijabai Technological Institute Mumbai India Email:firstname.lastname@example.org, email@example.com Abstract—Blackouts are characterized by a sequence of line trips and load shed which have a large impact on society. One of the models to predict the effect of a blackout is the Branching Process. The Branching Process model is utilized to compute the probability distribution of number of outages for a given power system. The mean propagation, a Branching Process parameter, is estimated from the simulated data to predict the size of blackout. The simulated cascading data is generated by
Research Plan for Doctor of Philosophy (Human Resource Management) By Akhilesh Gaur Assistant Professor Rajiv Academy for Technology & Management Mathura (Uttar Pradesh) Research Topic The proposed research work is going to attempt the study on the need and techniques of stress management. The title of the research proposed is Examining Stress and its management in a public sector unit. The research is proposed to elicit the causes of stress among employees of the public sector unit, and diagnosing the measures that can be considered to control stress level of employees. Introduction Recently, stress has been a matter of concern in rapidly changing industrial scenario. A health insurance brochure claimed that 90 percent of visits to a primary care physician were stress-related disorders.
Several research have been taken in the field of wet grinder. “Analysis and Improvement of Quality in Wet Grinder Manufacturing Industry through Customer Complaint Investigation”- L.Initha and et al. This paper proposes on existing problem in performance of wet grinder industry, which can be reduced. The investigation was carried out in wet grinder industry on customer complaint for the quality attainment of wet grinder. Quality tools like Pareto Diagram and cause & effect diagram are used to identify the problem area and causes.
