Temperature Dependence of the Viscosity Of Fluids

PERIODICAL. ChemickSr prum 10, pp. 533

TEXT: According to J.H. Perry (Ref. 3) the curves of the
temperature dependence of the viscosity of various substances
are very similar and therefore if, on the log q versus t
t is not in degrees Centigrade but in terms of the temperature
difference,a single curve is obtained for all substances. This
method was verified at the Research Institute for Synthetic
Rubber, n.p. Kauchuk in conversion calculations for various
temperatures of data measured by means of rotameters and a
considerable variance of the values was observed for various
types of substances.. On the basis of evaluation of the
temperature dependence for about 20 substances it was found
that the method could be made considerably more accurate if the
temperature difference is plotted in reduced values. If at
least two.viscosity values at.two temperatures are kPown. inter-
polation can be carried out on the basis of the equation.

Dependence of the Viscosity of Fluids
log I = A + B/T (1)
To enable plotting a generalised curve the constants A and
B were first calculAed for Eq. (1), in which T is
substituted by T for all the 20 substances under consideration.
r
By means of these constants, thederivations dT r/dlog q were ilv
determined for equal viscosity values of these substances and the
values averaged. It was found that the real values of the
derivations for equal viscosities, which characterise the slope
of the temperature-.dependence curves, are very close for the
various substances. The average derivations were plotted in a
graph against log q The generalised curve was then plotted
on the basis of graphical integration of the equation!

Contribution to the Simple Determination of the Temperature
Dependence of the Viscosity of Fluids
The curve of this dependence Is plotted in Fig. 1. To enable
accurate plotting of this curve numerical data are entered in
Table I for 20 subst-ances. The method was then tested by
0
c.alculating the viscosity values for temperatures about 40 C
higher-than the temperature for which the viscosity was known.
The thus calculated and experimentally determined results for
~2 for 20 substances are entered in Table II, which also contains
the values of the constants of Eq. (1) for the reduced temperature.
As an example, the viscosity of ethylbromide at 77.8 OC is
calculated from the known value at 30 0C (0-348 cP). The thus
calculated viscosity at 77.8 C is 0.233 cP as compared with the
measured value of 0.230 cP,

Title Stray Fields of Conical Pole Pieces
Orig Pub Chekhosl- fiz. zh., 1959, 9, No 2, 266-268
Abstract The author calculates the stray field of conical pole
pieces, intended for the production of an inhomogeneous
sector magnetic field, which varies in the meridian plane
in inverse proportion to the distance from the axis of the
field. Assuming that the pole pieces are not bounded iv.
the radial direction and that their surfaces are equipo-
tential, and also assuming that the air gap between them
is small, the author reduces the problem of finding the
stray field to the solution of the plane problem, obtained
by Coggeshall (Coggeshall I.I.D., Journal of Applied Physics)

TEXT.- The article which appeared originally in the Czech journal

giveV. comprises an analysis of the principles which may help to
improve the cutting power of metal cutting tools. In conducting
this study the author divides the cutting power P into three per-
pendicular components as shown in Fig. 1. The empirical formula
for estimating the PZ component, representing in most cases 90
of the total power acting upon a cuttirgtool, is:

licable only for chips with a thickness from 0.03 to 0.08 mm. The
specific resistance increases when thinner chips are cut. This is

SAE 1112 American steel as cited by W.R. Backer, E.R. Marschall
and LIX, Shaw (Ref. 2: The Size Effect in Metal Cutting-Transacti-
ons of the ASME, January, 1952, p. 61). Fig. 4 shows the specific
resistances for low carbon steel, Fig. 5 for carbon steel and Fig.
~6 for cast iron. According to Fig. 5, the specific resistance for
2
a feed where a, = 0.03 mm will be 550 kg/mm. , which means that one
tooth will cut a chip where F1 = b-CL = 10.0-03 = 0.3 mr2.
To cut
such a chip)the power required to act upon one tooth will be:
Q1 = F1, ksi =-- 0.3.550 = 165 kg.
If the same.chip is cut by two teeth, cutting one after the other
and each removing one half of the width, but with a doubled feed,
-'f the
the quantity of the removed material will be the same as i
chip were cut with one tooth. If the width of the chip is 5 mm
as shown in Fig. 7 -- the feed 0.06 mm And the specific resistance:
420 kg/mm2 , the power required to act upon one tooth will beol
Q2 F2' ks2 0.3-420 126 kg.

If the one tooth is loaded as much as in the previous case, it will
cut a chip 5 mm wide but thicker than 0.06 mm. The power of 165 kg
will be required to cut a chip with a thickness of 0.0905 at a
specific resistance of 360 kg/mm2, and a cross section of 0.452 mm~
If the whole width is cut by three teeth, each removing one third
of 1t, but with a tripled feed, t-he power required to act upon one
tooth will be:
Q3 = F3* ks3 = 0.3.366 = 110 kg.
If one tooth is loaded as much as in the first case it will cut
removing one third of the width, i.e. 3.33 mm achip thicker
than 0.09 mm. The power of 165 kg will be required lo out a chip
0.158 mm thick at a specific resistance of 314 kglMM4 and a cross
section of 0.526 mm2. If the number of sections increases into
which the whole.width is divided9 the quantity of the material re-
moved by one tooth using the same power increases also. Such a
group of teeth is called by the author a "toothed section". The
number of teeth in such a section should be equal to the sections,

in which the whole width is divided. Fig. 8 shows the estimated
cutting power increase for "toothed sections" when low carbon and
carbon steel are cut. Fig. 9 shows the same but for various kinds
of cast iron. The formula,P. = C - b . ay is applicable in ca-
pz pz
ses, where for F = cL.b, a, > 0. 1 . If the "toothed section" has n
.teeth, the width b of the chip should be divided into n sections.
If the whole depth is to be removed by a section having n teeth
with equal power acting.4'pon one tooth, the thickness cL of the
chip should increase u times. The power Pz required to act upon
one tooth for a section with n teeth will be;

is the lowest power increase achieved in removing material by
toothed sections. For thinner chips, for which the empirical,for-
mula for specific resistance is not applicable, the power increase
is even greater as shown in Figs, 8 and 9. The new regulations,for

removing materia"L. by dividing the chips, using toothed sections are
valid only for materials where the yp, is less than 1, but are not
valid if the thickness cLof the chip exceeds its width b. Fig. 10
shows the thickness of the chips for tools operating in sections,
compared with the initially removed thickness. The form of the
cutting edges, however, and its relation to the part removing the
material is not yet defined. The Issledovatellskiy otdel po me-
talloobrabotke (Metalworking Research Section) of the Chelyabinsk
Tractor Plant studied the influence of the chip breaker's form,
when used with reamers for round holes, according to D.K. MargUtiaL
(Ref. 4: Protyazhki peremennogo rezaniya (Stretchingsof a Variable
Cutting), Mashgizi 1956). Three kinds of reamers were used for the
study. The first frequently used in the CSR, where each tooth re-
moves a thin layer of the material, was equipped with chip breakers
as shown in Fig. 11 a. The chip breakers had the formof semi-cir-
cular channels, so that the angle between the cutting edge and the
chip breaker was 900. The first tooth removed a chip with a th, ck-I

ness s, and the tooth following the chip breaker - a chip with a
thickness 2s. After drilling a previously determined number of
holes, three kinds of we'ar appeared. The least wear I occured at
the place where the tooth was removing a chip with the thickness s
without a chip breaker as shown in Fig. 11 a. Similar wear occured
also when a reamer, in which the teeth following each other were
of the same height, but the first narrower than the second as shown:
in Figs. 11 b and 11 c. The third reamer used had the first tooth
divided in equal sections, so that the width of the cutting edge
was equal to the width of the chip breaker as shown in Fig. 11d.
The following tooth had its external diameter equal to the diameter
of the first one but worked without a chip breaker, removing only
the width left by the chip breaker. The chip breaker was sharpened
so that the angle it was 200. This time where s = 0.15 mm per tooths
only wear I occured. After reaming 650 parts, the wear amounted to
0.25 mm. The form of the chip breaker depends on its use, but the
most important is the angle -;t as shown in Fig. 12. Spiral drills

have only two cutting edges and can, therefore, be used only for
machining with a section consisting of two teeth as shown in Fig.
13. Each cutting edge, according.to the new method,.has sharpened,
,chip-breakers distributed in such a way that the width of the cutt-
ing edge is equal to that of the chip breaker. Thebasic princip-
les for an increase in the cutting power are (1) when machining is
done by n-toothed sections, the cutting edge will be interrupted
in such a way that the distance between the cutting edge, i.e. the
width of the chip breakerg is n-1 times reater than the length of
the cutting edge removing the material; ?2) the form of the dis-
tance between the cutting edges may differ. It is sufficient that
the angle between the cutting edge and the intermediate space be
150 to 250 (maximum from 80 to 450). It would, however, be better
t it by 10 or 20. When the thickness of the chip removed
