In dry cutting, the geometry optimization tool is very important. Standard tool should not be used dry cutting, for dry cutting should select the optimal tool geometry to reduce friction between the tool and chip machining of. Tool geometry optimization should be: first, to reduce the contact area of the tool / workpiece surface, such as the inverted cone drill should be reduced and helix angle; Second, consider the maximum lubricity of the tool surface, preventing the generation of BUE.

In addition, in dry cutting, the cutting edge of high-quality fine-grained carbide cutting tools and diamond tools can be used for small minor passivation its own matrix strength to maintain a sharp cutting edge, to reduce the cutting temperature. This tool not only to maintain high performance, but also to maintain optimum tool life.

In the case of dry cutting can not be fully realized, can be "the least amount of cutting fluid (minimal quantities of lubricant, mql)" technology to minimize the amount of cutting fluids, mql also known as quasi-dry machining (near dry cutting). Here the "minimum amount of coolant" refers to the process of supplying a small amount of cutting cutting fluid (when the machine is operating in the best conditions, cutting fluid consumption should be 50ml / h or less, while the use of the normal jet cutting fluid cooling consumption may exceed 6l / min).
