APPLYING SMED/QCO TOOL TO IMPROVE THE PRODUCTIVITY AT SCREWING STATION OF HFR ASSEMBLY – A STUDY AT ROBERT BOSCH (I) LIMITED

Nowadays the industrial product market is increasingly demanding more customized and quality products, forcing the manufacturers to cut down the price, in order to survive in the highly competitive product market. Working on this, Robert Bosch INdia (RBIN) Limited, Bangalore Plant (BanP) designs and produces Diesel systems which make vehicles more cleaner and economical. Bosch has to manufacture products as per the demands of every customer, economically, to maintain being the world’s leading manufacturer of diesel injection systems. Fuel Injection Equipment in diesel engine is the “Heart of the Engine” and plays a major role in its performance, emissions and reliability. Hot Forged Rail (HFR) finds its application in common rail fuel injection system, which stores the fuel at high pressure (1600bar). And at the same time, the pressure oscillation, which is generated due to the high pressure pump delivery and the injection of fuel are damped by the rail volume. Its design varies according to customer requirement and engine design. Therefore, BanP has to produce different types of rails to compete the diesel market in India. In order to be customer centric and productive, BOSCH follows Bosch Production Systems (BPS), the elements of BPS in Lean manufacturing are Value Stream Mapping (VSM), Value Stream Design (VSD) and Value Stream Planning (VSP). The Single Minute Exchange of Die (SMED) is one important lean manufacturing tool to reduce waste and improve production flexibility, allowing lot size reduction and manufacturing flow improvements. Quick Change over (QCO) is a set of activities (preparation, changing and adjustment) which are being carried out in between the production of two varieties to reduce changeover time and to reach the optimum production running. The proposed SMED approach was tested for screwing machines changeovers and the implementation had enabled reduction in setup time, through company’s internal resources without the need for significant investment. The objective of the present study is to implement the SMED/QCO tool approach in RBIN, BanP, HFR production line at screwing station to reduce the changeover time by 90% and improve availability by \u3e42%, thereby eliminating the possibility of investing on new production line to meet customer demand

A global reference database of crowdsourced cropland data collected using the Geo-Wiki platform

A global reference data set on cropland was collected through a crowdsourcing campaign using the Geo-Wiki crowdsourcing tool. The campaign lasted three weeks, with over 80 participants from around the world reviewing almost 36,000 sample units, focussing on cropland identification. For quality assessment purposes, two additional data sets are provided. The first is a control set of 1,793 sample locations validated by students trained in satellite image interpretation. This data set was used to assess the quality of the crowd as the campaign progressed. The second data set contains 60 expert validations for additional evaluation of the quality of the contributions. All data sets are split into two parts: the first part shows all areas classified as cropland and the second part shows cropland average per location and user. After further processing, the data presented here might be suitable to validate and compare medium and high resolution cropland maps generated using remote sensing. These could also be used to train classification algorithms for developing new maps of land cover and cropland extent

ZnS nanocomposite formation: Effect of ZnS source concentration ratio

186-189Thin films of ZnS-PVA nanocomposites have been prepared by chemical bath deposition (CBD) method by varying the concentration ratio of sulphur to zinc sources. The obtained films are characterized by XRD, TEM, UV-visible spectra, photoluminescence (PL) spectra and current-voltage (I-V) characteristics. The results show strong dependence on source concentration ratio. There is an increase in particle size and decrease in band gap with increase of S to Zn source ratio. PL spectra show decrease in intensity and blue shift with the increase in this ratio
