A
BSTRACT
The article discusses the practical experience of modernizing the 16K20F3 tool machine for tool
processing. It describes a deep modernization with a complete replacement of all drives, electrical and
control systems. The goal is to consider the use of modernization of outdated metal-cutting equipment for
modern technological tasks as one of the economically feasible options, alternative to the purchase of new
expensive equipment. The use of aggregation allows in the process of modernization to create
technological equipment for a specific group of products with the implementation of an optimal
technological process. Simultaneous equipping of the machine with a modern control system, as well as
assemblies and equipment for CAM technologies and HSM-technologies, allows you to get a qualitatively
new equipment.

The progress in all sectors of the national
economy is inextricably linked with the level of
development of the country's mechanical
engineering and machine tool engineering, which
is its main branch. It is also characterized by the
constant complexity of design due to the
requirements to reduce the time of mastering
new products.
The level of mechanical engineering largely
determines the quality and quantity of products
produced by all sectors that ensure the
functioning of the market economy. Therefore,
attention is being paid to the effective
development of mechanical engineering.
The development of computer technology, which
led to the creation of flexible production systems,
had a special impact on modern engineering. Such
complexes, formed on the basis of numerically
controlled control computers and machine tools,
as well as industrial robots, have firmly entered
the equipment of modern machine-building
plants.
The
restructuring
of
machine-building
production in our country led to a sharp decline
in the production of machine tools with digital
control and automation equipment for machine-
building. However, the development of a network
of small enterprises that could not afford
expensive automated technological equipment
led to the need to modernize the equipment,
including the CNC, which includes the 16K20F3
machine.
In such conditions, a new approach is needed that
meets modern requirements and is able to
increase
labor
productivity
with
small
investments with a constantly changing range of
manufactured products. .
Such upgrades are useful for small and medium-
sized businesses, because they allow to have a
minimum number of machines with many
different
processing
methods
in
their
composition. This direction was developed in our
master's
thesis.
Work
subject
is
the
modernization of the 16K20F3 CNC machine tool
to the turning-milling CNC machine tool.

In our country, it is inextricably linked with the
level of development of mechanical engineering
and machine tool engineering, which is its main
branch. The increase in the range of
manufactured products and the frequent changes
in production capacities, as well as the adoption
of new products is characterized by the constant
complexity of the design due to the requirements
of time reduction.
Modernization of an outdated machine tool with
aggregate elements for certain technological
tasks is one of the ways to solve the problem of
raising the general mechanical engineering and,
in particular, metalworking to a modern level
without large capital expenditures.

Advantages of modernization of machine tools
The main advantage of overhaul and
modernization of the machine tool is primarily to
increase its efficiency and accuracy of machining
while reducing costs. Complete overhaul of the
machine tool is the restoration of the machine
geometric system to the condition defined by the
general technical acceptance conditions of the
new machine tool, and hence to adapt the
machine to the minimum health and safety
requirements. Overhauled machines have the
advantage over new ones that their div is
already naturally seasoned, thanks to which we
avoid mechanical stresses. Such a div maintains
its geometry in the long-term perspective and
more effectively suppresses vibrations. In
addition, after the installation of a new control
system, the functionality of the machine increases
significantly and is equal to the new machine
tools. Depending on the complexity of the
machine, various control variants may be used,
e.g.
•
in simple machines
–
logic control system
based on relays and contactors,
•
with
more
complex
machines
–
recommended use of PLCs (the brand of the
controller is determined by the customer),
•
CNC numerical control in machines
requiring such system (Siemens, Fanuc,
Mitsubishi)
Depending on the scope of repair and
modernization of the machine tool, we can save
mark able cost which appears in relation to the
purchase of a new machine.
At FERPI MECH-TECHNO unitary enterprise, our
team brought a derelict 16K20F3 machine ready
for modernization by cleaning the div parts,
painting and taking all precautions. In addition,
we ordered and brought the necessary equipment
for the modernization of this machine from China.

Installation devices for the 16K20F3 machine.
• 3 servo motors (4 kW) and 1 (7.5 kW)
• CNC remote control
• Special cables
• Resistor 70 Ohm
• IO board
All three servo motors needed for the modern
upgrade of the 16K20F3 machine were mounted
on the machine in all axes. These servo motors
serve to perform movements along three axes,
and we have connected these motors to special
drives to ensure movement along all axes.

ESULTS
To modernize the 16K20F3 machine, servo
motors, servo drives, operation panels and a
number of push cables and relays were used. The
assembly of the electronic cabinet of the machine
tool is very beautiful and assembled according to
the standard. The machine tool is currently used
in the unitary enterprise "FERPI-MECHTECHNO".
The machine tool was assembled with high
accuracy and quality. Using the machine tool in
the preventive state required a lot of hard work.
When writing the program to the machine tool, G
codes were entered as letters, numbers and
numbers.

Modernization was carried out in order to solve
the issues of increasing the machine's
productivity and working capacity, as well as
expanding the technological capabilities that
allow processing parts of various shapes. The
16K20F3 CNC lathe has a special device for screw
milling. In the course of work, the optimal modes
of screw processing were selected based on
calculations and experiments. Motor-spindle is
also selected. The selection of equipment was
made using modern references and the Internet.
Maximum processing power, rotation speed and
minimum price were used as selection criteria.
The parameters of the developed special device
fully correspond to the requirements of the
technical conditions. Technical documentation
for the device has been prepared.
C
ONCLUSION
16K20F3 the process of modernization of the CNC
machine tool for turning - screw cutting. To
achieve production efficiency by equipping
existing local technologically unsuitable machine
tools with modern parts in machine-building
enterprises, and to achieve economic efficiency
by replacing expensive technological equipment
purchased from abroad with local technological
equipment, as well as other types of machine tool
and localization of modernization. The process of
modernization of the 16K20F3 lathe is to increase
the production efficiency by equipping existing
obsolete
machines
in
machine-building
enterprises with modern working parts, and to
achieve economic efficiency by replacing
expensive technological equipment purchased
from abroad, and to localize the modernization of
other types of machine tools.
