Hi there,
I have a small CNC mill, but haven't done too much work on it since I have converted it. This should be changing shortly.
What I was wondering is how I should be setting my machine up to machine double-sided parts (one-offs or maybe only a couple of each component). The machine has 3 axes and a 4th axis is not an option at the moment. I have read about machining one side and then turning the stock over to machine the other side. This sounds reasonable, BUT how do I accurately align the part once I have turned it over? Would my stock have to be accurately machined so that I can use the edge of it for a reference point? How are smaller, more complex parts normally machined when a 4th axis isn't available?
Sorry for the questions, but it would be useful to know.
Thanks
Warren
