The lathe will give you reasonably accurate parts straight off the machine. If you need something a bit more precise there are a few things you can do to increase your chances of getting a good part off first time.
These processes are aimed primarily at prototype and short run parts - a large production run has very different goals and targets so will approach roughing and finishing differently.
Warm up the machine
At the very least make sure the spindle is warmed up.
Bury the nose of the tool
Turning tools have a nose radius - this is typically the absolute minimum radial depth of cut you should be taking. Ideally you should be cutting with 2 or 3 times the nose radius.
Shallower depths of cut may be causing the insert to rub across the surface instead of actually cutting. This can affect accuracy and surface finish.
Deeper depths of cut will also encourage the chip breakers moulded into the tool to work properly.
