Although almost any book and/or text on metal cutting, cutting tool design, and
manufacturing process discusses to a certain extent the tool geometry, the body of
knowledge on the subject is scattered and  confusing. Moreover, there is no clear
, ~; Q  i1 G& k4 W6 i! [objective(s) set in the selection of the tool geometry parameters so that an answer
to a simple question about optimal tool geometry cannot be found in the literature
on the subject. This is because a criterion (criteria) of optimization is not clear, on
1 F* c) v4 M% \8 W8 x: Hone hand, and because the role of cutting tool geometry in machining process
optimization has never been studied systematically, on the other. As a result, many
- C8 _8 K4 N. J; z( Dpractical tool/process designers are forced to use extremely vague ranges of tool
geometry parameters provided by handbooks. Being at least 20+ years outdated,
9 [# K& ?# p0 Q4 L7 G9 Q/ }these data do not account for any particularities of a machining operation including
a particular grade of tool material, the condition of the machine used, the cutting
fluid, properties and metallurgical condition of the work material, requirements to
; O7 c3 T2 T9 M1 Cthe integrity of the machined surface, etc.
Unfortunately, while today's professionals, practitioners, and students are
interested in cutting tool geometry, they are doomed to struggle with the confusing
0 }% `2 |! F# h0 f$ ?! v8 l$ s( bterminology. When one does not know what the words (terms) mean, it is easy to
slip into thinking that the matter is difficult, when actually the ideas are simple,
easy to grasp, and fun to consider. It is the terms that get in the way, that stand as a
  t6 Y9 F% Y: n6 R/ R7 [1 ewall between many practitioners and science. This books attempts to turn those
walls into windows, so that readers can peer in and join in the fun of proper tool
$ e  q: O5 V$ u+ \$ v: edesign.
6 [& p+ @* x; z  R3 ^* P& p/ [. h5 jSo, why am I writing this book? There are a few reasons, but first and foremost,
because I am a true believer in what we call technical literacy. I believe that
6 X3 v1 u" L3 {8 H, A# n+ meveryone involved in the metal cutting business should understand the essence and
importance of cutting tool geometry. In my opinion, this understanding is key to
6 `+ n2 v( U* k4 v9 ?! M/ R1 }improving efficiency of practically all machining operations. For the first time, this
book presents and explains the direct correlations between tool geometry and tool
0 ~: o. E; [9 V# _performance. The second reason is that I felt that there is no comprehensive book
on the subject so professionals, practitioners, and students do not have a text from
which to learn more on the subject and thus appreciate the real value of tool
+ D. Z9 B# W, k. \, g8 Wgeometry. Finally, I wanted to share the key elements of tool geometry that I felt
were not broadly understood and thus used in the tool design practice and in
optimization of machining operations in industry. Moreover, being directly
& F$ C0 o! u! y/ }involved in the launch of many modern manufacturing facilities equipped with
2 h3 s1 F$ M5 C5 X) p4 a% c) cstate-of-the-art high-precision machines, I found that the cutting tool industry is not
ready to meet the challenge of modern metal cutting applications. One of the key
" i8 y- }8 H0 }' K  iissues is the definite lack of understanding of the basics of tool geometry of
' P$ F- T' R9 j* w0 g; x  d& M1 Q* Fstandard and application-specific tools.
The lack of information on cutting tool geometry and its influence on the
outcome of machining operations can be explained as follows. Many great findings
0 k, q$ j+ G/ E# K- eon tool geometry were published a long time ago when neither CNC grinding
machines capable of reproducing any kind of tool geometry were available nor
9 ~6 c# j2 G' d; ewere computers to calculate parameters of such geometry (using numerical
: p, B  ^& J, a. emethods) common. Manual grinding using standard 2- and 3-axis simple grinding
) p1 l- G8 O: v( Z- ?' Q  Cfeatures was common so the major requirement for tool geometry was the simpler
the better. Moreover, old, insufficiently rigid machines, aged tool holders and part
fixtures, and poor metal working fluid (MWF) selection and maintenance levered
any advancement in tool geometry as its influence could not be distinguished under
these conditions. Besides, a great scatter in the properties of tool materials in the
) r9 L5 \) z& R0 rpast did not allow distinguishing of the true influence of tool geometry. As a result,
studies on tool geometry were reduced to  theoretical considerations of features of
. y) l3 V" ~* S, v; otwist drills and some gear manufacturing  tools such as hobs, shaving cutters,
shapers, etc.  
8 n9 \# r; w1 g$ ]+ N% GGradually, once mighty chapters on tool geometry in metal cutting and tool
design books were reduced to sections of few pages where no correlation between
' @5 g2 b$ k0 U% }tool geometry and tool performance is normally considered. What is left is a
7 E$ R' c- {5 P( v( ^general perception that the so-called “positive geometry” is somehow better than
“negative geometry.” As such, there is no quantitative translation of the word
4 w: L" x1 D& y& h6 V3 `“better” into the language  of technical data although a great number of articles
/ R4 e* ~- S& x+ U5 c# ^( H. Y- @& `1 fwritten in many professional magazines discuss the qualitative advantages of
2 w7 r4 _5 {2 v0 U/ O' k! C5 h# o2 o“positive geometry.” For example, one popular manufacturing magazine article
+ ]0 f. s0 U& Cread “Negative rake tools have a much  stronger leading edge and tend to push
against the workpiece in the direction of the cutter feed. This geometry is less free
cutting than positive rakes and so consumes more horsepower to cut.” Reading
these articles one may wonder why cutting tool manufacturers did not switch their
; V+ G" D0 L. [, mtool designs completely to this mysterious “positive geometry” or why some of
them still investigate and promote negative geometry.
& R: `% M, `0 h4 dDuring recent decades, the metalworking industry underwent several important
# L& A- `  N4 D9 m1 D$ x9 x  Ochanges that should bring cutting tool geometry into the forefront of tool design
