TITLE: Nature of Growth at Metal Cutting
PERIODICAL: Tr. Tullsk. med. in-ta, 1958, Nr 8, PP 3 - 10
ABSTRACT: There are two basic hypotheses on the causes of the
occurence of
growth. According to the first, growth is formed of metallic
particles
which are out off by the tool from the cutting surface and
squeezed by
the pressure of the chips coming off. According to the second
hypothesis
growth represents the dead zone of the metal of the chips which
is formed
in front of the face of the tool under certain temperawre
conditions.
Both hypotheses give rise to a number of objections. The
investigations
of the grasping of 'the meta13 at their joint plastic
deformation does
much for the comprehension of the nature of growth. Ii was found
out by
tests that the grasping of metals, i.e. the formation of stable
temporary
Card 1/2 connections between touching surfaces can take place at
room temperature

SOV/123-59-~15-;-595E)6
on the Nature of Growth at Metal Cutting
and at!higher ones. Obviously the grasping of metals is based on
diffusion, It can be
assumed that the formation of growth takes place as a result of
the grasping of materials
of the tool and that of the chips interlocking at their plastic
dc-P014mation during the
cutting process. 6 figures, 10 references.

TEXT: Practice of machining titanium and its alloys

that the effects of coolants are greater although different from
the case of carbon and alloyed steels. The article quotes the
re-
aults of experiments on determining the effect of some coolants

coefficient of friction ji due to free cutting of titanium BT 1
(VT

V~
properties of metal and condit-ttione of machining are
indicated.
zte average coefficient of fri6tion was assessed as the ratio of
force of fric*ion to the normal force. Forces on the back
surface
of tool were not taken into consideration. Twelve coolants were
tested and the results tabulated. The figure illustrates average

coefficients of friction, obtained during machining in various
me-
diae Observation on chip formation revealed that pure titanium
is
not apt to build upp although intensive adherence of its
particles
on the front edge of tool was noticed. Notwithstanding the high
plasticity of titanium, deformation of the chip in air is small
which may be accounted for.by the low average coefficient of
fric-
tion. Data allow the following deUctions to be made. In
contrast
to carbon andElloyed steelBp watered coolants do not reduce
fric-
tion coefficient of titanium, but do increase it. The average
coef-,~
ficient of friction when cutting steel 20X (20Kh) in water
coolant
reduces former by.half as compared to machining in air. A
similar
decrease was noticed when using emulsions and other fluids. The
application of mainly lubricating fluids which reduce friction
when
machining steel, has little effect on cutting titanium. Olein
acid
and fluid no. 2, which contain a surface activating additive
rela-
tively reaace little the average friction coefficient, whereas
such
activated fluids as petrol or fluid no. 1l causetits increase.
The
most effective fluids for reducing friction are mineral
graphitized
oil, fluid no. 2t spindle oil and "sullfofrezol"p i.e.
lubricants

TEM The author considers the problem of determining electric
conductivity
In a limited region of the Earth on the basis of the theory of
electromagnetic
induction within an inhomogeneous lead. The problem Is solved for
the case when
X(conductivity) increases with the depth, and the special case of
X= const..
The solution is carried out in rectangular and cylindric coordinate
systems. In
rectangular coordinates, the conductivity is given by the relation:
X = ;Gexp
[-2m(z-zl)/zo], where m is an integer > 0, X3 = const., z, is the
plane separat-
ing the lead from the dielectric; z0 is a plane tangential to the
Earth's surface.

nates. Formulae are derived for the partition of the field of
magnetic variations
observed at the Earth's surface into the external and internal
parts. From the
data of 12 observatories on 8 of variations in summer 1933, the
conductivity and

(see lable 1) point
out the inhomogeneity in the distribution of conductivity within

The calculation of the induced field with a distribution of

distribution of
conductivity, inhomogeneous in latitude, on the induced field is
carried out.
The distribution of conductivity over the .9urface of a spherical

In the form 7/(1 + oos e) , where X0 is the average conductivity

data of S i -monies PI ana P

exists, a series of harmonies in the induced lield corresponds to
every harmonic 14
in the inducing field. The results of analysis show that for a
sufficiently
large value of X0 the inhomogeneous distribution of conductivity
over the lati-
tude does not affect the induced field, i. e., the same harmonic in
the induced
field corresponds to every, harmonic of the inducing field, The
amplitudes of the
other harmrnlos are so small that they can practically be neglected.
For smaller
values of X,,, the inhomogeneity in distribution of conductivity
affects noticeably
the induceci field, and it is necessary to take into account in
calculations a
series of other harmonies in addition to the basic harmonio.

TEXT: Construction and mounting of a new quartz variometer
for measuring
the total intensity T of the terrestrial magnetic field in
magnetic ob-
servatories is briefly described in this paper. The author
gives a de-
tailed description of the sensing element in the present
periodical, P. 55.
The first experimental type of the apparatus was developed
and produced in
1959 by the kvartsevaya laboratoriya IZMIRAN (Quartz
Laboratory of the
IZMIRAN). In 1960, the mentioned laboratory produced the
first experi-
mental lot of such variometers in cooperation with the otdel
opytnogo
priborostroyeniya IZMIRAN (Department of Experimental
Instrument Construc-
tion of the IZMIRAN). The universal sensing element (Fig. 1)
is the basis
of the apparatus. The quartz system is adjusted such that the
temperature
coefficient of the element equals zero, and that rotation
axis and mag-

netic axis of the suspension system lie J., a plane parallel to
the upper
casing surfacep the light spots of the movable mirror and of the
fixed
mirror being bound to coincide on the recorder. The temperature
coaffi-
0
cient of the adjusted apparatus is + 0.2y per 1 , and may be
neglected.
The adjusted element is attached to the support so that the
rotation axis
of the suspension system is perpendicular to the rotation axis of
the
support. The upper casing surface has to be perpendicular to T in
order
to direct the element properly to the direction of the total
intensity T.
The zero point can be varied up to � 5000Y with the aid of
additional
magnets (Vicalloy, temperature coefficient 5 - 10- 5). The first
experi-
mental variometer was mounted at a distance of 3.5 m from the
recorder in
the variation pavilion of the Tsentral ,naya magnitnaya,
observatoriya
(TsMO) (Central Magnetic Observatory (TsMO)). The scale
graduation was
1-33Y per 1 mm, the temperature coefficient PT;zz:'0.2y per 100
The stabili-
ty of the fundamental values was controlled first by comparing
the readings
of the variations obtained directly with the T-variometel to the

February 1960, a nuclear precession magnetometer has been used at
the
TsMO'for absolute observation of TI its readings are used to
control
those of the T-variometer. The cheakings showed that the
fundamental
values of the T-variometer did not change within 4 months.

air,
high stability of the fundamental values, and simple

TITLE: Universal high-stability sensing element with a zero

TEEXT: Starting from 1957, experimental research on different ver-
sions of quartz systems for recording the vertical component of
the
earth's magnetic field was carried out in the quartz laboratory
of the.!ZMIRAN (Institute of Terrestrial Magnetism, the
Ionosphere,*
and Radiowave Propagation, kS USSR). As a result of 'his research
the author designed a high-stability sensing element with a zero
0
temperature coefficient for magnetometers, variometers, and micro-
variometers recording any component of the earth's magnetic field.
The article considers: a) A short history of the question, b) a

new magnetic suspension pystem for quartz frames, c) the universal
sensing element's design, and d) three ways of compensating for

uhe U
perature of the quartz systems. The essence of the first
meth;d of obtaining a zero temperature coefficient consists of the
fact that the axis on which the magnet is mounted on the quartz
bar shifts to the side of the magnet's south pole for'a certain
distance 1; this distance is.chosen in such a way that the changes
in the susnension system's position, occurring at the expense of
the magnetic moment's change and the magnet's linear expansion,
are mutually compensated. This method is suitable only for the
ver-
tical comDonent Z and the total strength T of the earth's magnetic
field. The second, classical method of temperature compensation
is attained at the expense of an additional compensating magnet
and is a-pplicable for quartz systems, recording any component of
t'_,-.Ie earth's magnetic field with a normal sensitivity.
Theessence of
the third way consists in the fact that two antiparallei magnets,
whose summary field completely compensates the field of the com-
ponent being recorded, are fastenedon the quartz frame; the due
-selection of the temperature coefficients of these magnets
ensures
Card 2/3

S/169/62/000/005/066/093
Universal high-stability D228/D307
that the compensatiln-,i lCield's value remains constant when
the tem-
jerature changes. The alignment of the suspension system on an
witwisted thread in the zero field ensures the high (-0.1e sen-
sitivity of the system, which is of substantial significance in
the recording of microvariations. The data about the work of the
sensing element, established at the TsentralInaya magnitaya ob-
servatoriya. (Central Magnetic Observatory) for recording varia-
tions in the total force T have been previously stated in detail

ABSTRACT: In 1962, the quartz lal~oratory of the Institute of
Terrest~ial Magnetism,
the Ionosphere, and Radio Wave Propagation developed the
TZMIRAN-2 magnetic-varia-
tion station for magnetic observatorles~ The apparatus is shown
schematicall 'v in
Fig. I of the Enclosure, It consists of a rectangular box I
within which there are
three housings, 2, 3, and 4, with quartz sensing elements for
recording variLtions
in declination D, the horizontal component H, and the vertical
compo-iient 2, of the
earth's magnetic field. In the front wall of the station there
are three sDherical
lenses ~ vith identical focal lengths. On the rear wall, there
are three bars 6
-with movable carriages 7 and compensating ra-agnets 8, which are
used for chang,4nr,
the zero point and the graduations of the corresponding sensinj-,
elements, Desicca-
tor 9 is mounted at the top of the device. The housing of the Z
variometer is
attached to the floor of the station, the D variometer, to the
side wall, and the

is used for
conpensating the magnetic fields created by the H and Z sensing
elements at the
center of the D sersing element. on the bottom of the station there
can be an addi-
tional magnet 12 for compensating the necessary part of the field of
the horizontal
component H. Current is supplied through plug 13. The IZMIRAN-2 can
be adapted
for'recording magnetic storms, ordinary variations, and

ABSTRACT: The removal of twisted metal shavings is a very
disagreeable
process. At the Pervyy 'Josudarstvennyy podshipnikovyy zavod
(First State Bearing Plant) this problem has been solved in
introducing special one and multi-worm transporters installed
at the automatic roller and ball bearing production lines.
For the removal of cast iron shavings and because of their
friability, one-worm transporters are used; multi-worm trans-
porters are recommended for steel shavings. The article gives
a detailed description of the shaving transportation schemez
The productivity of one shaving transporter amounts to 300 kg
of shavings or Approximately 3 cu m per hour. The total dis-
tance of transportation is 65.5 m. There are 4 schematic drawings.

ABSTRACT:
The storing
device automatically performs the following

functions: receives
the components from the preceding

work bench and transmits the
parts to the following

bench, with equal or different speeds.
It can have the

form of barrels or chain conveyers, the latter
being

pr'eferred. The cabin conveyer can be manufactured with

two or four cylinders. The construction of the cabin

conveyer
is more complicated and expensive, but it

allows the loading
and unloading of the conveyer from

many points. It also allows
an increase in volume, al-

though not in height, which is very
important for saving

ABSTRACT:
Automation of the 1GP3 plant has beer accomplished by
the

introduction of several conveyor lines performing the

movement of work pieces and their inter-operational

distribution
among separate machines. The general lay-

out of a conveyor line
is given in Fig. 1. Its opera-

tion comprises, on the whole, the
following stages: The

work pieces are taken from the bunker (1)
and delivered

by the lifter (2) to the conveyor-distributor (3)
from

where they go to the metal-cutting machines (4). The

inter-operation movement is carried out by outleading

conveyors
(5) located beside the machines. Fig. 2 shows

the charger having
150 cm in diameter; its operation

consists, essentially,
of the following stages: The

parts are'taken from the bunker (8) by a conical ro-
tating device and brought to the tray (10) from where
they are taken by the claws (16) and transferred to
trays (17 and 18); thereupon they are hoisted by a
lifter and placed on the conveyor belt. The lifter is
shown in Fig 3. Distributing conveyor (Fig. 4) con-
sists of a case (1) inside of which there is a cavity
for placing of parts; under the case special trays
(4) through which the work pieces come to machines
are provided. In Fig. 5, a diagram of receiving device
is given; its purpose is to grab the work pieces and
to deliver them to trays. The speed of work pieces
movement along the conveyor line is determined by for-
mula Vi = V where v is the belt movement speed, and
is Y:A the coefficient of slip = o.9-0.92. The
length of conveyor is 35 m; required drive power - 1 kw.

ABSTMOT: Hydraulic braking devices for workpieces moved by

,Paper under review. These inclined feeder-troughs are
described generally in the introduction, and a construction
example is shown. The fact that'the workpieces moving under
the influence of gravity obtain too great speeds, and de-
formations of the workpi.eces occur, is mentioned as
the,main
fault. Belts used as brakes cause a stoppage of the
movement,
while the hydraulic brakes described here only slow down
the movement. Drawing of two brakes of that kind are shown
in figures,2 and 3, with the actual braking cylinders being
practically identical. The operating principle of these
hydraulic brakes is the following2 During their movement,
the workpieces meet a lever arm, Thich is connected to the

of lever rods. The move-ment of the workpieces is trans-
mitted by the lever rods to the piston, which is braked by
the oil in the brake cylinder. The own weight of the lever
rods or a weight placed on the lever arm, always returns the
braking device back to its initial position. These brakes
showed good results when used in the automatic device 1GPZ.

TITLE: Transportation Systems of Automated Machining Lines
PERIODICAL: Mekhanizatdya i avtomatizatsiya proizvodstva,
1960A NO. 10, pp.7-12
TEXT: A general review is made of the design principles of
transportation
systems for automated transfer machine lines used in the USSR,
with a few compari-
sons with foreign designs. The review includes the
transportation system of a
piston machining line (Fig. 1) and of a line machining
shafts(Fig. 2); the trans-
fer principle of the "rotary lines" of L. N. Koshkin (Fig. 4);
of Morozov "group
line" (Fig. 6); the N. M. Knyazlkov system (Fig. 7); the A. A.
Sigodzinskiy
system (Fig. 8); and V. P. Bobrov system (author of the
article). The Koshkin
lines belong to the synchronous type, i. e. all working and
transferring drums
arranged in two staggered lines working simultaneously,
including the rotors
doing ancillary work (inspection), the entire system driven
from one transmission
shaft with bevel gears, or other combinations. The work rotors
of the Koshkin
line are cylinders with grooves on the outside designed for
holding tool blocks
(punch and die, or other). The shank of each tool is connected
to a roller that
Card 1/8

S/118/60/000/010/002/008
Transportation Systems of Automated Machining Lines A161/AO26
enters a curved groove on a stationary copying drum (6 in Fig.
4), so as to lift
or lower the tools when the work rotor turns. Blanks are fed
from an automatic
loading device into the grips of the first transfer rotor,
then they go into the
tool blocks on the work rotor, and the tool in the tool block
performs all its
work motions during one revolution of the work rotor. Then the
blank goes on to
the next transfer rotor and into the next operation, and so
on, The duration of
one operation cycle can be varied by the'-number of tool
blocks or positions on the
work rotor. Koshkin lines are presently used mostly for
stamping, inspection,
thermo-chemical and combination operations, and some for
machining. In stamping
lines with high pressure needed for punches, special hydraulic
heads are used.
These lines are stopping when one rotor in the system fails;
this is their draw-
back. But such lines can be set up from rotary machines
(Bullard-Continuous 128,
or "Krasnyy proletariy" machines) and a flexible transfer
system. The tool blocks
are easily replaced during idle runs, and attempts have been
made to automate the
replac;Wnt. A line may have machines arranged in-line (Fig, 5)
with non-synchro-
nous transfer, or in groups, with single machines working into
the hopper of the
next and with transfer by conveyers. The workpieces will
accumulate in the hopper
of a stopped machine, but the other machines need not stop.
'The ln.3 (1GPZ)
plant uses several transfer systems, the oldest of which is
the Morozov system

(Fig.,6) with a multitray conveyer (1) running along the entire
line and having
branches to every machine; inside the trays the blanks are
moved by cross pieces
fixed between two endless chains and fall through holes on the
branch conveyers.
The transfer system is electrically blocked to prevent crowding
of a tray at a
stopped machine. Another system (at IGPZ) is the Knyazkov
system (Fig. 7) with a
conveyer and longitudinal trays above it and one lift (5)
between a pair of
machines (2). Another transfer system, by Sigodzinskiy (Fig.
8), has one way
leading to differentimachine groups. Its conveyer has separate
numbered zones for
each workpiece, and the zones repeat periodically. The loading
station of this
system (1) is a group of skip hoists with numbers for the
different workpieces
being machined. In its top position the feeder skips the blank
on the distributing
conveyer (5). (Similar lifts are placed between machines). The
distributing
conveyer is placed overhead and has a cam chain (7) and an
angle tray with cams (8)
moving the blanks; another chain (9) on top is moved
reciprocatively by hydraulic
pistons (10) and engages constantly with all lifts on the line.
The ratchet stops
(11) by which-this chain grips the chain (7) slip over the cams
in backward motion.
Blanks are fed to machines through a window with shutter in the
tray. This system
Is not fully flexible, too, and has to stop when the conveyer
stops and blanks are
out in trays. Still, it is relatively simple and suitable for
multiple-nomenclahim
