Abstract :
Glass substrates were micromachined using electro chemical discharge machining. The developed tool holder allows to scan the substrate surface as well as machining it in a closed loop. The developed control algorithm for drilling holes allows to achieve relatively high machining speeds (up to 30 μm/s) and deep structures (up to 1 mm). Micro-channels up to a depth of 100 μm were machined in one step with a removal rate of 4.5·105 μm3 /s. Reported are some examples of machining micro-holes, micro-channels and modification of existing pattering
