Electric discharge machining is non conventional machining process used for machining of hard materials which cannot machined by conventional machining process. Electric discharge machining is an electro sparking method of metal working involving an electric erosion effect. A pulse discharge occurs in a small gap between the work piece and the electrode and removes the unwanted material from th...

Bio technologies, electronic components, MEMS or watch industry require handling and positioning of ever smaller micro-parts (ten to hundred μm size). Several tools used for such tasks, called micro-grippers have been developed based on different catching and releasing principles. Vacuum grippers are mainly used in the macro world and have been successfully downsized to fulfill micro-world appl...
