TITLE: Improvement of the dimensional stability of a cutting
tool by the method of elastic compensation (Povysheniye
razmernoy stoykosti rezhushvhego instrimenta metodom
upruge3r kompensatsii.)
PERIODICAL: Mv" i Instrument" (Machine Tools and Tools), 1957,
No.2, pp 24 - 28 U.S.S.R.)
ABSTRACT: In metal cutting, especially turning, the cutting endur-
aace of the tool considerably exceeds its endurance limitation
due to the gradual shift in the mean dimension. Althou& the
random scatter also increases as the cutting proceeds, the
compensation of the shift of the mean dimensions can consid-
erably increase the practical tool endurance. This compensa-
tion can be accomplished on the basis of the number of machined
components or the cutting time or by feeding back the result
of direct measurement of the component dimension. It can
also be carried out by making use of the change in the cutting
force which takes place with the blunting of the tool*. Res-
earch woxk carried out by the VNII Tool Research Institute
has led to the design of a toolholder based on a new principle
of the increase in the total cutting force component situated
1/3 in the plane of the tool planform. This total component can

be further resolved into the axial (parallel with the main
spindle) and radial components. Of these, the radial force
always causes springing back in its own direction but the
axial force can be made to advance or withdraw the cutting
edge according to the geometry of the elastic deformations of
the tool holder. The practical condition:Which ensures that
the compensating tool holder does not increase the scatter
between the components, is that the change in the component
size under the effect of the radial force component does not
exceed twice the change under the axial component. Thus
elastic compensation of the systematic error can be accompl-
ished without increasing the scatter, either when the dimen-
44onal wear factor is small or when the effect of the wear
on the axial force is large. This occurs with a large plan-
form angle of the tool. A variable stiffness tool holder is
illustrated. The prismatic tool carrying the cutting tips is
supported against the radial and tangential cutting f orces by
separate pins. These pins butt against tapered stops. The
axial force tries to turn the tool about on axis passing
through the stops. This causes the tool to press against a
2/3 pusAft which deforms a leaf spring, *wse stiffness can be

adjusted by screws. Histograms of cutting dimensions resulting
from an ordinary tool holder and a compensating tool holder
in cutting mild steel are compared at a cutting speed of 60
m/min feed of 0.238 mm/rev. and depth of cut of 2 mm. A dinft-
sion skim of a compensating tool holder developed from the
experiments reported is given, together with a formula for the
initial adjustment of the negative stiffness.

TITLE: Prepa-r-a-fionand Utilization of Protective Atmosphere
from Technical Nitrogen
PERIODICAL: Stals, 1959, Nr 91 PP 854-861 (USSR)
ABSTRACT: A description of the plant producing protective
atmosphere for muffle furnaces, laboratory work on
catalytic decomposition of ammonia and purification of
nitrogen from oxygen are given. The atmosphere is
produced from technical nitrogen containing about 3% of
oxygen (from the oxygen plant) and ammonia. The diagram
of the plant - Fig 1. Liquid antmonia is filtered,
evaporated and passed into dissociation reactor (Fig
mixed with nitrogen and passed into a reactor for
catalytic removal of oxygen, then cooled for the removal
of moisture (2 stage cooling). Final drying is done by
passing through a column of alumogel (which is
regenerated by blowing hot air). In laboratory
experiments (apparatus - Fig 2) a suitable catalyst was
developed (TsEChM-1). The comparison of the activity of
Card 1/3 the catalyst with that of Rashig iron rings is shown in

Fig 3. The catalyst is made up of two layers - the
first layer contains for each ioo cm3 of the carrier,
7.5 g of Ni and 4.0 g of MgO and the second layer,
3.0 g of Fe, 4.5 g of Ni and 4.0 g of MgO. At present
the retort for the dissociation of ammonia is being
redesigned according to the scheme shown it, Fig 5. As
a catalyst for the removal of oxygen, copper-nickel
catalyst an a-alumina beads TsECM-2 at 3500C was found
to be most suitable. Catalytically active components
(copper and nickel) as well as the promoter (A1203) are
introduced in the form of nitrates (for each 100 S of
the carrier 3g )f NI, 4.5 g of Cu and 1.5 g of A1203)-
The design of the oxygen purification reactor is shown
in Fig 9. Typical compositions of the protective
atmosphere during annealing of strip from steel U10A and
alloy steel Kh05 are shown in Fig 10 and 11 respectively.

the formation of a structural disturbance. Moreover, it was found that
phase hardening changes the stability of various austenite zones, and
that the martensite crystals formed in the cooling of austenite are con-
siderably smaller than those formed in the cooling of annealed austenite.
The diagrams of Fig. 2 graphically show the structural chan-Ses, and
details of such changes are discussed. Diagram B in Fig. 2 shows the
broadening of the line (311) of austenite, and diagram V shows the micro-
hardness. The complex interrelations show that the annealing process takes
place not only within a range of temperature in which quick recrystalliza-
tion occurs, but also at considerably lower temperatures. Finally, the
results obtained by investigations of the annealing process of strain-
hardened austenite are given. It was0found that daring annealing in the
temperature range of from 450 to 550 C the stabilization process is in-
creased. A broadening of the X-ray interference lines is observed already
at 35000. Thus, it may be said that the change in the crystal structure
of austenite in direct and inverse martensite transformation leads not
only to a stabilization of austenite, but is also the cause of the
changes occurring as a result of subsequent annealing, as is shown by the
increasing stability of austenite against martensite transformation. There

effect of this process by analyzing thu experimental material so far

of the 'last ten years for martensite transformation in strong cooling and

transformation, With a given M cool' M heat is a constant fcr each alloy
that does not depend on the preliminary treatment, Experimentally, the
course of isothermal transformation was investigated in an Fe-Ni--Mn 0

(Figs. 2,3). Also in this case the autocatalytic character of transformation
was confirmed. The rate or transformation increases rapidly up to
M-1960 ~ 5%; a lesser increase was observed at M - 1960 ' 10%~ Further-more,
isothermal transformation Was investigated unde-z conditions under which
the transformation rate is low. As may be seen from Fig- 4, the trano-
formation rate undergoos an acceleration that even after thr- lh-ir~ hiss
not yet reached its maximum, There -ire 4 fig-ures and 24 --eferences"
