Hi all, I'm a former manual milling and turning apprentice. After completing my apprenticeship in 2003 I went straight into vechile fitting with the MOD where I have remained ever since. I'm looking to return to CNC machining but I haven't touched a machine since 2003. Has anyone got any advice on any courses I could do to stand a chance of being employed as a CNC Setter/Operator (I already hold C&G Part programming). Or perhaps any training software I could use to practice on?

Many thanks in advance :)!
