Chapter 6 Nursalbiah Machining Wear

When the tool wear reaches an initially accepted amount, there are two options, 1. to resharpen the tool on a tool grinder, or 2. to replace the tool with a new one. This second possibility applies in two cases, (i) when the resource for tool resharpening is exhausted. or (ii) the tool does not allow for resharpening, e.g. in case of the indexable carbide inserts.
