Accuracy seems to result in those "ticks" you hear as you're mining. The more accurate you are, the more resources you get out of that node, represented by  the top row of five icons filling up on the mining HUD (one tick fills up half an icon).

The cutter upgrades don't feel like they make it easier to mine or increase accuracy, but the range at which the cutter can detect the nodes goes up (30m for the normal cutter versus 45m for the focused cutter). Not sure of the advanced cutter has additional features, since no one has it yet.
