Micro-blasting has established itself among the mainstream machining processes for difficult-to-cut workpieces like glasses, carbides, ceramics, etc., by using abrasive particles. Initially, during micro-blasting process non-machined areas are covered by protective mask. Today, either mask fabrication practice or micro-blasting process, none is secretive in the area of micro-manufacturing, but in the previous work, those processes were well suited and optimized for producing micro-features on planar workpieces. However, the demand for micro-features on 3D freeform substrate in MEMs and...

A tunable fuzzy logic based servo controller for monitoring and control of the Micro- EDM process has been developed, which uses the behavior of discharge pulses. The fuzzy logic applies a heuristic approach in dealing with the non- linear and time varying nature of the micro-EDM process. The control parameters affecting the performance of micro-EDM include gap voltage and gap current discharge pulses. It is important to discriminate between different levels of pulses for proper operation of micro-EDM. Discrimination of pulses from an RC-type power source is still an ill- defined problem...

La transformation de la mangue au Burkina Faso n'est pas optimale. Les sous-produits issus de cette transformation ne sont pas traités correctement pour obtenir d'autres produits finis tels que les aliments bétails, combustibles. Les formulations des aliments bétails, combustibles à base de sous-produits de mangues ne sont pas maitrisées par les acteurs de la transformation et à cela s'ajoute le problème de conservation. L'objectif global est d'améliorer la transformation des sous-produits des mangues par la construction d'une technologie utilisant de l'énergie propre avec un...
