quality is ensured.
Cutting tools are usually provided with a rounded corner. Figure 5.9 shows
the surface prole produced by such a tool under ideal conditions, where the
peak-to-valley surface roughness R

The surface roughness increases at higher feed rates and decreases while
using a larger nose radius (Figure 5.10). The same gure also indicates the
decrease of surface roughness at high cutting speeds. Increasing the depth ...
