U¿yteczna wiedza zawarta w ksi¿¿ce mo¿e sprawi¿, ¿e produkcja stanie si¿ bardziej produktywna bez zwi¿kszania jakichkolwiek zasobów produkcyjnych. Ksi¿¿ka ta jest przeznaczona dla mened¿erów, in¿ynierów odlewni oraz pracowników produkcji i montäu na pierwszej linii. Jednym z najskuteczniejszych sposobów wykorzystania tej ksi¿¿ki jest czytanie i omawianie jej z innymi pracownikami. Kädy rozdziä zawiera refleksje w formie "Rzeczy do zapami¿tania", które s¿ pomocne w stymulowaniu dyskusji grupowej pomi¿dzy zainteresowanymi pracownikami w odlewniach. Czytelnicy dowiedz¿ si¿: Definicja przezbrojenia, Znaczenie krótszych uk¿adów, Istniej¿ce ograniczenia odlewnicze, Proponowana metodologia maj¿ca na celu wprowadzenie prze¿omu w uk¿adach maszyn odlewniczych oraz dziesi¿tki konkretnych pomys¿ów na popraw¿ uk¿adów matryc. Niniejsza praca wyjänia równie¿: Jak wykonä badanie czasu w celu zmierzenia rzeczywistych ustawie¿, Jak przeanalizowä dany zestaw za pomoc¿ arkuszy SMED i dalej, jak zidentyfikowä "w¿skie gard¿o" lub dziäania cz¿stkowe za pomoc¿ kombinacji wykresów Pareto i analizy przypadku g¿ównego, odpowiednio. Omówiono równie¿ wp¿yw dobrego gospodarowania (5S), TPM, Poka-yoke i zestawu narz¿dzi Set-up na ogólne zmiany. W ksi¿¿ce potwierdzono jej wyniki za pomoc¿ "Studium przypadku".

Friction Stir Welding is a fairly recent technique that utilizes a non consumable rotating welding tool to generate frictional heat and plastic deformation at the welding location, affecting the formation of a joint while the material is in the solid state. The basic principle of FSW involves simultaneous application of pressure and relative motion, generally in a rotational mode, between the components to be joined. From the available literature, it has been observed that the effect of welding parameters on desired characteristics was determined by taking into consideration one parameter at a time or by using conventional methods like, One Factor at a Time (OFAT) technique. So without ignoring the limitations of earlier researches, the main focus in this study has been kept on welding of dissimilar alloys (specifically AA6061 and AA5086) by using Design of Experiments (DoE) which is quite rarely used Multi-Factor at a Time (MFAT) technique. Therefore, the ultimate objective of the work is to optimize critical to process parameters (CPPs) of FSW process for achieving mechanical characteristics within ranges. This book contains quite rare information as far as FSW is concerned.

The useful knowledge contained in the book can make manufacturing more productive without increasing any input resources. This book is written for managers, foundry engineers and frontline production & assembly associates. One of the most effective ways to use this book is to read and discuss it with other employees. Each chapter includes reflections in the form of ¿Things to Remember¿ which are helpful to stimulate group discussion among the concerned work force on foundry shop floors. The readers will learn; Definition of Changeovers, Significance of shorter Set-ups, Existing Foundry constraints, Proposed methodology to bring breakthrough in the Set-ups of Die casting machines and dozens of specific ideas to improve die set-ups. The present work also explains; How to perform Time- study to measure actual Set-ups, How to analyse the given Set-up with SMED sheets and further how to pin point the bottleneck activities or sub activities by using combination of Pareto charts and root case analysis, appropriately. It also discusses the impact of good housekeeping (5S), TPM, Poka-yoke and Set-up tool-kit on overall Changeovers. The book validates its findings through a ¿Case study'.
