Tool-to-Part or Part-to-Tool?

Whether the tool is guided to the workpiece, or better the workpiece to the tool, usually depends on the size, shape properties and ‘grippability’ of the workpiece.

For a better form analysis, clarity and thus planability of the paths, moving the tool on the workpiece is closer.

For which tasks the opposite is true, has to be developed on the basis of relevant practical examples.
