Appeal No. 97-0593
Application 08/365,906
DECISION ON APPEAL
This is a decision on appeal from the examiner's
refusal to allow claims 1 through 5, 7, 8 and 10 through 16
as amended subsequent to the final rejection in a paper filed
March 25, 1996 (Paper No. 9). Claims 6 and 9 have been canceled.
Appellant's invention relates to a cutting insert for
cutting a workpiece by removing chips of material therefrom and,
more specifically, involves a cutting insert with a chipbreaker
that effectively breaks thin, foil-like chips that result from
fine cuts of the workpiece. As indicated on page 2 of the
specification, these thin, foil-like chips have a thickness that
may vary between .005 and .009 inches and are more difficult to
curl and embrittle to the extent necessary to cause them to
continuously break into small pieces. The invention is broadly
described in the paragraph bridging pages 3 and 4 of the
specification as follows:
[T]he cutting insert comprises an insert body
having a cutting edge defined by an inter-
section of top and side relief surfaces, and
a chipbreaker configuration including the
combination of an elongated groove disposed
on the top surface of the insert adjacent
