Sommario/riassunto |

This report is part of a broader effort by the World Bank Group to understand the motives and challenges of small entrepreneurs in fragile and conflict-affected situations (FCS). The report's key finding is that, compared to entrepreneurs elsewhere, entrepreneurs in FCS have different characteristics, face significantly different challenges, and thus may be subject to different incentives and have different motives. Therefore, it is recommended that both the current analytical approach and the operational strategy of the World Bank be informed by the findings that follow. The report summarizes |

Sommario/riassunto |
|
This book updates our knowledge on the metal cutting processes in relation to theory and industrial practice. In particular, many topics reflect recent developments, e.g. modern tool materials, computational machining, computer simulation of various process phenomena, chip control, monitoring of the cutting state, progressive and hybrid machining operations, and generation and modelling of surface integrity. This book addresses the present state and future development of machining technologies. It provides a comprehensive description of metal cutting theory, experimental and modelling tech |
