Machinability of cast iron was investigated from the viewpoint of chip formation, tool life, and surface finish.
Cutting mechanism of cast iron was analysed based upon the flow region concept. The effects of depth of cut and rake angle on the cutting process were discussed.
The most suitable tool material for cutting cast iron was selected and effects of cutting conditions on tool life were investigated over a wide range.
Machinability based upon surface finish was discussed in connection with tool wear.
