What exactly is drilling?
Drilling is a machining manufacturing process which is used to create boreholes in various materials. Since all geometry values of drill and cutters are known this production method counts to the “machining with geometrically defined cutting edge”. Turning and milling also count to this manufacturing process.
Along with the process “Lower and Rub” everything is defined in DIN 8589, because all methods have the same kinematics , inother words, the same relative movement between the workpiece and the tool.
