ABSTRACT: Tests are reported designed to determine experimentally
the best de-phasing angles of the separate'milling cutters in a
gang milling set-up so as to reduce the cutting torque fluctua-
tion to a minimum. Careful tool grinding reduced the cutter
eccentricity in these tests below 0.03 mm. engineering steel
(0.39o' C) with a tensile strength of 48 kg/mm and grey cast iron
with a Brinell hardness of 130 were machined on a horizontal
milling machine at d8pths of cut of 2-10 mm (corresponding to
contact arcs of 10-45 and a range of advances per tooth between
0-05 and 0.2smm. Most tests were carried out at cutting speeds
of 15-40 m/min apart from one series of high-speed tests run
at 150 m/min. No coolant was used. Strain gauges bonded to
the cutter mandrel transmitted the cutting torque through a
carrier wave system. The tests included gangs consisting of
cylindrical, face, angle and form cutters. The relative angular
positions were shown to cause large differences in tool life.
Cardl/2 An analysis is given followinE the realisation that fluctuations

The Determination of the optimum Angular Shift of Milling Cutters in
Gang Milling
in the instantaneous cross-section engaged by the gang are the
main reason for uneven cutting torque. The geomtrical
analysis includes the cases of form cutting by angle and
radius cutters, the milling of slots with disc cutters having
straight or helical teeth, surf-ace milling with cylindrical
cutters and the General case of arbitrary shape cutters. The
improvement in the work of the milling machine is expressed
by the improved utilisation of the power installed and by an
increased efficiency (from 65 to ?5%).
There are 5 figures, 1 table and 3 Russian references.

TITLE: On the Accuracy of Milling with Disc Cutters
PERIODICAL: Vestnik mashinostroyeniya, 1959, Nr 6, pp 63-64 (USSR)
A13STRACT: The effects of the face wobble of the cutter, the axial
wobble of the spindle assembly of the milling machine,
the misalignment of the table feed motion and the overall
stiffness of the machine on the accuracy in milling of
slots and steps by disc-type milling cutters Is exaluined
analytically. A graph (rigure 2) shows the experimentally
determined stiffness cbefficient as a function of the
cutting force. The wobble of the cuttcr and its mandrel
were tested under load. The initial wobble of 0.03 mm
increased under load to 0.06 mm. By reducing the iength
of the mandrel and by appropriate pre-loading of the cutter
spindle roller bearings, the error of the axial dimensions
could be reduced from 0.05 to 0.02 mm. In gang milling,
the optimum relative phasing of the cutter teeth can
substantially reduce the total cutting force (author's
paper in this journal, 1958, Nr 2). The tests have shown
Cardl/2 that the misalignment of the table feed motion yields the

ABSTRACT: The author investigates the absorption'capacity ofoxygell.
for,temperatures of 2000 - 4000 degrees (generated by shook
waves). -2he experiments in which G.14. Tekiyeva pagticipated
show that in the temperature interval 2500 - 4000 K-and for
the wave length A - 2272 1 the absorption capacity A
(ratio' of the intensities of the absorbed and of the falling
light) lies about between 0-4 and 0.6 . The divergence of
the results of measurement and-the deviation from the
theoretically calculated values is reduced to the fact that
the light was not completely monochromatic.
