That is not too unreasonable.
However, to Ahmed, we, in order to make recommendations that fit what you want to do, do need to know what it is that you want to do. Things like 'how big is the part this so far vaporous machine needs to handle?" What is it made of? Method of machining? (std metal cutting/edm/plasma/hot-wire-for-foam) or? Some idea of the speed and accuracy requirements. And anything else that might bear on how we recommend to proceed. >2008/11/11 Ahmed Elghamrawi <[EMAIL PROTECTED]> > >> Brothers and Sisters, >> >> We are a group of final year students in Cairo university, Egypt.
