Abstract
The machinability of sintered stainless steel 430LHC has been investigated under dry drilling conditions, varying sintering atmosphere, manganese sulphide content, drill diameter, feed, and cutting speed. The results are presented as tool life–cutting speed diagrams and converted to cost–cutting speed relationships for a realistic set of production parameters. The tool life is related to tribological aspects, hydrogen sintering and the effect of admixed manganese sulphide in improving machinability. The experimental results allow production costs to be minimised in a quantitative way. PM/0717
