Abstract: Competence management comprises the management, building, leveraging and deployment of strategic and operational competencies, the causal relationships and linkages between them, and the way competencies are embedded in organizational and individual resources. In-house development and external acquisition to contextual factors, for small manufacturing firms, such as the firms’ strategic orientations are inter related. This paper presents a detailed case study in a two wheeler manufacturing unit.Keywords: Manufacturing Competency, Strategic Success, Case Study, Two Wheeler Manufacturing Unit

Abstract: As global business competition shifts from efficiency to innovation and from enlargement of scale to creation of value, management needs to be oriented towards the strategic use of human resources. Core and managerial competencies are not specific to any occupation. One could demonstrate the competency of “teamwork” or “client orientation”, for example, in performing any job. Specific technical competencies are not included in the model of United Nations competencies for the future. To complement the core competencies, individual departments may choose to define functional competencies related to their respective areas of work. This research involves development of model for Manufacturing Competency and Strategic Success for automobile manufacturing unit. The model has been developed by using SEM based on AMOS 21.0

Abstract: Micro, Small and Medium Enterprises (MSMEs) have been noted to play a significant role in promoting economic growth in less developed countries, developing and also in developed countries. Worldwide, the micro and small enterprises have been accepted as the engine of economic growth of any nation. Small and Medium Enterprises are the backbone of the economies, because it trigger employment, output, export, poverty alleviation, economic empowerment, economic development etc. in developed as well as in developing countries. It is more important to developing countries as the poverty and unemployment are burning problems. MSMEs have been playing a momentous role in overall economic development of a country like India where millions of people are unemployed or underemployed. Therefore, the growth of small sectors is essential for the growth in the GDP, employment generation, total manufacturing production and export. India, being one of the fastest growing economies of the world, needs to pay an honest attention for the utmost growth of MSMEs for its increased contribution in above areas.

Abstract: Micro, Small and Medium Enterprises (MSMEs) make a significant contribution, by reducing unemployment in India. They need to operate efficiently and productively in order to maximize their contribution to nation, as well as national economies. MSMEs play a significant role in the economic growth of the country owing to production, exports and employment. They contributes 8% to the countrys GDP, 45 % to manufactures output and 40% to the countrys exports. It provides employment to 60 million people. The aggressive competition situation arising out of globalization and liberalization is forcing the organization across the globe to realize that their survival is not feasible in the absence of technological innovation. Technology innovation reflect a critical way in which organization respond to either technological or market challenges. Therefore, the importance of technology innovation in organizations competitiveness is an undeniable fact. The literature reveals that most significant determinants of technology innovation associated with MSMEs are technological collaboration and monetary management. These determinants are relatively significant in improving the manufacturing performance of MSMEs.

Abstract: In this paper, the effect of different wire electrodes used in wire electrical discharge machining (WEDM) on the machining characteristics of AISI D3 die steel has been presented. Three process parameters, namely type of wire (brass wire, zinc coated wire and composite wire), pulse on time and peak current have been considered. The process performance is measured in terms of cutting speed and surface roughness. The research outcome will identify the important parameters and their effect on performance characteristics while machining AISI D3 material with different wire electrodes. The analysis of variance (ANOVA) of multilevel factorial design indicated that all the selected parameters have significant effect on the performance characteristics. The study indicated the improvement in surface roughness with brass wire over other wires. Maximum cutting speed was obtained with composite wire as compared to zinc coated and brass wire. Additionally, scanning electron microscope (SEM) examination highlighted important features of machined work piece surface.

Abstract: The wire electrical discharge machining (WEDM) is widely used for machining workpieces having complex geometries. A wire electrode of diameter 0.25 mm is moved coaxially between two guides and electrical energy in the form of electrical pulses is applied to remove material from the workpiece. In this study, the effect of key process parameters on wire wear of shallow cryogenic treated brass wire electrode used in WEDM was investigated experimentally. Five process parameters, namely Type of wire, Pulse width, Time between two pulses, Wire tension and Servo reference voltage have been considered. Taguchi experimental design has been applied to investigate the optimal parameters for minimum wire wear ratio (WWR). The experimental results indicate that Type of wire; Pulse width and Time between two pulses have a significant effect on WWR. The analysis of variance of mean and analysis of variance of S/N ratio on data was performed to identify the significant factors in order to establish the relative significance of parameters for WWR. It is found experimentally that shallow cryogenic treatment decreases the WWR. Increasing pulse width increases the WWR, where as increasing Time between two pulses decreases WWR. The results have been validated by three confirmation runs for optimum WWR.
