Following John Stuart Mill, for example, one can claim that autonomy is "one of the elements of well-being" (Mill 1859/1975, ch. III). Viewing autonomy as an intrinsic value or as a constitutive element in personal well-being in this way opens the door to a generally consequentialist moral framework while paying heed to the importance of ...

CNC mills are generally more accurate than CNC routers, as the accuracy of a CNC machine heavily depends on its rigidity, among other factors. CNC mills can reach accuracies of 0.01mm with the right CNC mill, quality tooling, and optimal operating conditions. This accuracy is why a CNC mill is ideal for machining hard metals.

The tools are generally made with hard materials like tool steel and carbide. For example, end mills, slot drills, ball cutters, etc. Moreover, choosing the types of CNC milling operations according to 3D design ensures the optimal result. For instance, face operations smooth surfaces, while thread operations precisely cut threads.

The main difference between a rod mill and a ball mill is the grinding medium. Rod mills use long steel rods as the grinding medium, while ball mills use steel balls. Additionally, rod mills are better suited to handling larger feed sizes, and they create a more uniform particle size distribution than ball mills.

For example, the bottom of the pocket just mentioned must be machined flat, and since face mills are generally too large to fit inside a workpiece, an end mill is the only option. Also, most face mills (though not all) cannot machine a square shoulder, so once more, an end mill or shell mill must be used.
