As i am sure all of you know a fundamental design aspect of milling machines is structural rigidity.Having three (at least) moving axis and ensuring that the
tool follows the designated path accurately is essential. Indeed all other aspects such as control software , and drives depend on the machine design.
I am inviting those interested to share what information we have on small
(x300mm , y200mm , z50mm as guide to size) machines capable of working steels up to say 316l stainless.
