By experiments in cutting copper, brass, and Al alloy with diamond tools having various kinds of crystallographic orientation, to observe the effects of cutting force, and friction between tool and chip, the following conclusions are obtained.1. It is apparent that the Mercator method is superior to the Stereo method for representing crystallographic orientations such as the tool face (rake face, flank) of a single-crystal diamond tool, and the edge inverse direction (nearly equal to a chip's flowing out direction).2. A cutting force is subject to crystallographic orientations which become large with rake faces in the order of {100}, {111}, and {100} plane.3. A cutting force may be reduced by making an edge inverse direction pointed in a coefficient of friction decreasing direction, even if it is the same rake face.4. The coefficient of friction between rake face and chips increases as the actual depth of cut decreases by reducing feed. The extent of the increase depends on the crystallographic orientation at the flank. This is because the flank's coefficient of friction overtakes that of the rake face, the rate of increase depends on the crystallographic orientation of the flank.

用不同晶向的金刚石刀具切削铜、黄铜和铝合金，观察切削力和刀具与切屑之间摩擦力的影响，得到以下结论：很明显，墨卡托方法在表示单晶金刚石刀具的刀具面（前刀面，侧面）和边缘反方向（几乎等于切屑的流出方向）等晶体学方向方面优于立体方法。切削力受晶体取向的影响，在{100}、{111}和{100}平面上，切削力随刀尖面增大而增大。即使是同一前刀面，也可以通过使刀刃反方向指向摩擦系数减小的方向来减小切削力。前刀面与切屑之间的摩擦系数随着实际切削深度的减小而增大。增加的程度取决于侧面的晶体取向。这是因为侧面的摩擦系数超过了前表面的摩擦系数，增加的速度取决于侧面的结晶取向。
