Abstract:
The appearance
of adhering layer formed on tool face, its composition and
distribution are analysed when Ca-S free-cutting stainless steel
is machined. Cutting temperature field and its relation with
formation of the layer is also studied. The result shows that,
the layer can be formed under proper temperature condition, the
stable cutting temperature field keeps the stable layer, its
thickness and composition distribution along rake face depend on
the corresponding cutting temperature field. The theoretical
model of the layer formation is set up.
Key words:
