Abstract:
This Report deals with the machinability of Firth-Vickers
materials.
Reference REX WO (Stainless Steel) in the hardened and
tempered condition* U,T.S 70-75 tons; Brinell hardness
321 minimum, 375 maximum.
CONTENTS:
SECTION 1 The development of a single point
cutting tool (Lathe Tool).
SECTION 2 The application of this tool to the
turning process to determine the
optimum surface speed and best feed
rate.
SECTION 3 The determination of the life of
the cutting tool when used at
optimum surface speed and best
feed.
SECTION 4 The modification of the single point
tool to meet a special requirement;
i.e. to be applied as a single tooth
in a face milling cutter which is
suitable for use when face milling
Rex 1018 sheet in the hardened and
tempered condition.
The machining process must be designed
to result in the minimum distortion in
the finished component and give a good
surface finish. Further, it is
desirable that the finished dimensions
shall be achieved at one pass and an
area of 32 square feet be covered
between re-grinds of the milling cutter.
SECTION 5 Conclusions.
SECTION 6 Results of practical application.
Report on results of the application
of the proposed cutter design, etc.
