I can give you the dimensions of my Tsugami S16D machine which is a smaller machine that a 32mm standard machine but will give something more than what you have now..
Machine is 7 feet wide from machinists point of view and 4" deep(210cm wide and 120cm deep). The magazine style barfeeder I have will fit a 12' long bar and has still 6' of "pusher" still behind that making the barfeeder 18' long (540cm). So the whole package is 7.5 meters long. Behind the lathe I have 36" (90cm) of space to allow the back elec. cabinet door to be fully opened and worked on-when it's closed, I have a tool box on wheels behind it. In front I keep a 120cm walking space to drive a pallet jack passed the machine.
A 32 mm machine might have bigger w and d dimensions but but a few 10's of cm's I would think.
Hope this helps getting started..
