2. Principle of a typical machine
The principle of a chip-removing machine tool is very simple: a workpiece is moved in front of a tool (fixed or moving). This relative displacement results, if there is tool/workpiece interference, in the removal of material, which we call machining.
most of the material removed must belong to the workpiece. However, most machining processes also involve the removal of material from the tool; this is wear whose effect is not always harmful (cf. self-regeneration of grinding wheels or honing stones).
According to the conventions of elementary physics, a material point – and therefore a part made up of an infinite number of points – has, relative to a fixed spatial reference frame, six degrees of freedom. If this reference frame is a trirectangular trihedron, the movement...
