The difference between climb milling and conventional milling centres around the rotation of the tool in relation to the table feed.

In climb milling operations, the cutter rotates with the feed. This method is best used proactively on a CNC machine, mainly because CNC milling machines have none to very little backlash in the lead screw. The swarf is evacuated behind the cutter so the risk of re-cutting the waste material is slim when running at higher RPM and feed rates.

During conventional milling the tool rotates against the feed rate direction. This method of milling is commonly used on manual machines and allows the table to take up the slack in the lead screw, maintaining an accurate position on the machine table.
