Text A: Machine operator with a PC

Today, machine tools with program control are used in both the machine-building and
woodworking industries. There are drilling machines with a PC for drilling printed circuit
boards, there are EDM machines - with their power you can cut a very complicated
configuration in metal, and the processing accuracy is amazing ... You can’t list all types of

10

machines with a PC. Almost any modern production basically has programmable machines and
to work on them it is not enough just to be able to "push the buttons." The specialist should have
an idea of the manufacturing technology of parts, the tools used, and know the appropriate
software.

What does a machine tool operator with a PC do? He has many responsibilities. He checks
and fixes work pieces and tools on the machine, determines the operating mode, controls
machine operation and process flow.

In the process, the operator monitors the quality of products, makes measurements of parts
with special instruments. Working conditions for the machine operator with a PC today to call
quite comfortable - this is work in a warm, clean, well-lit room. Physical loads are insignificant.
Most of the operator’s working time is occupied by mental work, but if, for example, the
technologist at the given production is a theoretician in pure form, then the operator should “feel
the material”, know, if you like, the features of his character. That is why the machine operator
with a PC must have knowledge - deep and specific.

A metal is an element, compound, or alloy that is good conductor of both electricity and
heat. Metals are usually malleable and shiny.

Metals are materials most widely used in industry because of their properties. The study
of the production and properties of metals is known as metallurgy.

The separation between the atoms in metals is small, so most metals are dense. The atoms
are arranged regularly and can slide over each other. That is why metals are malleable (can be
deformed and bent without fracture) and ductile (can be drawn into wire). Metals vary greatly in
their properties. For example, lead is soft and can be bent by hand, while iron can only be
worked by hammering at red heat.

The regular arrangement of atoms in metals gives them a crystalline structure. Irregular
crystals are called grains. The properties of the metals depend on the size, shape, orientation, and
composition of these grains. In general, a metal with small grains will be harder and stronger
than one with coarse grains.

Heat treatment such as quenching, tempering, or annealing controls the nature of the
grains and their size in the metal. Small amounts of other metals (less than 1 per cent) are often
added to a pure metal. This is called alloying (легирование) and it changes the grain structure
and properties of metals.

All metals can be formed by drawing, rolling, hammering and extrusion, but some require
hot-working. Metals are subject to metal fatigue and to creep (the slow increase in length under
stress) causing deformation and failure. Both effects are taken into account by engineers when
designing, for example, airplanes, gas-turbines, and pressure vessels for high-temperature
chemical processes. Metals can be worked using machine-tools such as lathe, milling machine,
shaper and grinder.

The ways of working a metal depend on its properties. Many metals can be melted and
cast in moulds, but special conditions are required for metals that react with air.

Forced rotation turning appears to be an effective machining method due to higher tool life, time
efficiency and acceptable quality. Several studies have been carried out to investigate the basic
characteristics of forced rotation machining. So far, tools are used whose design included several
components. However, such tools may generate vibrations, which are undesirable in the process.
In engineering practice, most vibration problems are solved by reducing the cutting parameters
(cutting speed and feed rate), which reduces machining productivity. For this reason, a new type
of monolithic rotary tool has been designed that eliminates the design complexity and high
assembly accuracy requirements of current rotary tools. Based on the performed experimental
research, it is possible to define the influence of cutting parameters on the cutting force. Next,
the equation of the cutting force and the resulting roughness of the machined surface was
determined. In the introduction, the results of the analysis of machining parameters with a rotary
tool were added. The presented solution fundamentally validates the new monolithic tool for
forced rotation technology and defines its application for different machining materials.

edge wears beyond being useful, they can be reground. However, even when suitable
replacement tools are available, tool changing is time-consuming and can add considerably to the
processing time. In order to address this problem, cutting tool inserts or tips were developed.
These are disposable cutting tools and usually have a number of cutting edges. The number of
cutting edges will depend on the insert shape and whether a negative rake angle has been
incorporated into the tool holder, which allows both sides of the insert to be used for example, a
square insert will have eight cutting edges (Amstead et al., 1987). The inserts are usually
clamped into a tool holder, a typical example of which is shown in Fig. 5.34. Inserts may also be
brazed into the tool holder. However, clamping is generally the preferred method as this allows
the insert to be rotated or indexed to the next cutting edge (Kalpakjian, 1995). There are a
number of ISO standards that have been developed to help in the selection of both tool inserts
and holders for various machining processes.

A.Abrasive grains are blunt compared to conventional cutting tools. Effective rake angles are
highly negative which leads to a large compressive plastic zone ahead of and under the grain
followed by a shallower tensile zone behind the grain.

It was shown in Chapter 14 that the depths of grain penetration are usually very small. This has
implications for the geometry of the grain contact. The grain can be considered as an extremely
blunt cutting tool. Many of the grain contacts will not produce a chip but will merely rub against
the workpiece. The forces and friction involved in grinding can be explained by considering the
different types of contact involved in grinding. The following discussion outlines some basic
models of abrasion. A useful test of a model is whether it can explain values of force ratio
experienced in rubbing, ploughing, and cutting.

C.Unexpectedly rapid increases in urbanization throughout the world, especially since World
War II, have brought many problems, including congestion, air pollution, loss of scarce surface
area for vehicular ways, and major traffic disruption during their construction. Some cities
relying principally on auto transport have even found that nearly two-thirds of their central land
area is devoted to vehicular service (freeways, streets, and parking facilities), leaving only one-
third of the surface space for productive or recreational use.

D.Machine tool, any stationary power-driven machine that is used to shape or form parts made
of metal or other materials. The shaping is accomplished in four general ways: (1) by cutting
excess material in the form of chips from the part; (2) by shearing the material; (3) by squeezing
metallic parts to the desired shape; and (4) by applying electricity, ultrasound, or corrosive
chemicals to the material. The fourth category covers modern machine tools and processes for
machining ultrahard metals not machinable by older methods.

E. Hundreds of varieties of metal machine tools, ranging in size from small machines mounted
on workbenches to huge production machines weighing several hundred tons, are used in
modern industry. They retain the basic characteristics of their 19th- and early 20th-century
ancestors and are still classed as one of the following: (1) turning machines (lathes and boring
mills), (2) shapers and planers, (3) drilling machines, (4) milling machines, (5) grinding
machines, (6) power saws, and (7) presses. The engine lathe, as the horizontal metal-turning
machine is commonly called, is the most important of all the machine tools.

А.Монолитный инструмент

Монолитный инструмент изготовляют двумя способами. Первый способ заключается в
том, что нужная форма инструмента в окончательном виде формируется в специальной
прессформе. Исходным материалом является мелкозернистый порошок с химическим
составом, соответствующим определенной марке твердого сплава. Затем полуфабрикаты
подвергают двукратному спеканию. Если полученный инструмент имеет форму коронок,
то его припаивают к державкам, а затем затачивают. Если инструмент насадной, то его
затачивают и надевают на соответствующие оправки.

B.Конструктивно монолитные инструменты

31

Конструктивно монолитные инструменты выполняются в двух вариантах: цельными - из
заготовки, получаемой методами порошковой металлургии ( прямым прессованием и
спеканием или окончательным спеканием обрабатываемой в пластифицированном
состоянии заготовки), и составными - когда цельной изготовляется только коронка или
головка, припаиваемая затем или механически закрепляемая на державке.
Обработка монолитными инструментами осуществляется при обильной подаче
смазочно-охлаждающих жидкостей ( СОЖ) или вовсе без них. Недостаточная подача
СОЖ или перерывы в ее подаче могут значительно ухудшить работоспособность фрез и
другого инструмента. Обработка пластмасс производится всухую или с воздуш -: ным
охлаждением. При нарезании резьбы вручную хорошо зарекомендовала себя смесь
парафина с солидолом в соотношении 1: 1, а при машинном нарезании - смесь его с
маслом в той же весовой пропорции

The results of calculating the stress-strain state in replaceable cutting inserts of assembly tools
are presented, using the finite element method. In the calculation, the mechanical characteristics
of the tool hard alloy were specified, the conditions for the interaction of the replaceable cutting
inserts with the drill body, the fastener elements, the force loading was replaced by the
specification of the boundary conditions. As a result, a number of basic sizes of replaceable
cutting inserts were built, with different geometric parameters. A system of equations for the
calculation of cutting forces for drilling with prefabricated drills of different types has been
developed. To determine the influence of the shape of the plates on the stressed state, replaceable
cutting inserts of different shapes were studied: trihedral, rhombic, square. A new form of
replaceable high-strength cutting inserts with an enlarged angle has been developed. To
improve performance, the auxiliary cutting edge of the replaceable cutting insert is made in the
form of an arc inscribed in a quarter of the length of the side of the polyhedron, while the radius
of the curved cutting edge is equal to half the length of the side of the polyhedron.

In the context of machining, a cutting tool or cutter is typically a hardened metal tool that is
used to cut, shape, and remove material from a workpiece by means of machining tools as well
as abrasive tools by way of shear deformation. The majority of these tools are designed
exclusively for metals. There are several different types of single edge cutting tools that are
made from a variety of hardened metal alloys that are ground to a specific shape in order to
perform a specific part of the turning process resulting in a finished machined part. Single edge
cutting tools are used mainly in the turning operations performed by a lathe in which they vary in
size as well as alloy composition depending on the size and the type of material being turned.
These cutting tools are held stationary by what is known as a tool post which is what manipulates
the tools to cut the material into the desired shape. Single edge cutting tools are also the means of
cutting material performed by metal shaping machines and metal planing machines which
removes material by means of one cutting edge. Milling and drilling tools are often multipoint

35

tools. Drilling is exclusively used to make holes in a workpiece. All drill bits have two cutting
edges that are ground into two equally tapered angles which cuts through the material by
applying downward rotational force. Endmills or milling bits, which also cut material by
rotational force. Although these tools are not made to put holes in a workpiece. They cut by
horizontal shear deformation in which the workpiece is brought into the tool as it's rotating. This
is known as the tool path which is determined by the axis of the table that is holding the
workpiece in place. This table is designed to accept a variety of vises and clamping tools so that
it can move into the cutter at various angles and directions while the workpiece remains still.
There are several different types of endmills that perform a certain type of milling action.

Grinding stones are tools that contain several different cutting edges which encompasses the
entirety of the stone. Unlike metallic cutting tools, these grinding stones never go dull. In fact the
formation of cutting edges of metallic cutting tools are achieved by the use of grinding wheels
and other hard abrasives. There are several different types of grinding stone wheels that are used
to grind several different types of metals. Although these stones are not metal, they need to be
harder than the metal that they grind. In contrast to the grinding stone, if the hardness of the
metal exceeds that of the stone, the metal will cut the stone. This is not ideal. [1] Each grain of
abrasive functions as a microscopic single-point cutting edge (although of high negative rake
angle), and shears a tiny chip.

Cutting tool materials must be harder than the material which is to be cut, and the tool must be
able to withstand the heat and force generated in the metal-cutting process. Also, the tool must
have a specific geometry, with clearance angles designed so that the cutting edge can contact the
workpiece without the rest of the tool dragging on the workpiece surface. The angle of the
cutting face is also important, as is the flute width, number of flutes or teeth, and margin size. In
order to have a long working life, all of the above must be optimized, plus the speeds and feeds
at which the tool is run.

Linear cutting tools include tool bits (single-point cutting tools) and broaches. Rotary cutting
tools include drill bits, countersinks and counterbores, taps and dies, reamers, and cold saw
blades. Other cutting tools, such as bandsaw blades, hacksaw blades, and fly cutters, combine
aspects of linear and rotary motion.

Cutting is one of the oldest arts practised in the stone age, but the cutting of metals was not
found possible until the 18th century, and its detailed study started about a hundred years ago.

Now in every machine-shop you may find many machines for working metal parts, these cutting
machines are generally called machine-tools and are extensively used in many branches of
engineering. Fundamentally all machine-tools remove metal and can be divided into the
following categories:

1. Turning machines (lathes). 4. Milling machines.

36

2. Drilling machines. 5. Grinding machines.
3. Boring machines.

Machining of large-volume production parts is best accomplished by screw machines.

These machines can do turning, threading, facing, boring

and many other operations. Machining can produce symmetrical shapes with smooth surfaces
and dimensional accuracies not generally attainable by most fabrication methods.

Screw-machined parts are made from bar stock or tubing fed intermittently and automatically
through rapidly rotating hollow spindles. The cutting tools are held on turrets and tool slides
convenient to the cutting locations. Operations are controlled by cams or linkages that position
the work, feed the tools, hold them in position for the proper time, and then retract the tools.
Finished pieces are automatically separated from the raw stock and dropped into a container.

Bushings, bearings, nuts, bolts, studs, shafts and many other simple and complex shapes are
among the thousands of products produced on screw machines. Screw machining is also used to
finish shapes produced by other forming and shaping processes.

Most materials and their alloys can be machined — some with ease, others with difficulty.
Machinability involves three factors: 1. Ease of chip removal. 2. Ease of obtaining a good
surface finish. 3. Ease of obtaining good tool life.

1. The cutting tool is that part of a machine tool which serves for removing material from a
revolving work. Cutting tools being used for various metal cutting operations include quite a
wide range of shapes. The shape of the tool is known to depend upon a large number of factors
such as the specific operation the material to be cut and the material the tool is made of. If either
incorrect or faulty cutting tools had been used for metal-cutting operations, the quality of work
would have become poor and cost would have been higher. That is why careful attention should
be given to the cutting tools in any metal-cutting operation.

2. Cutting tools are made of hardened steel or alloy metals. All the cutting tools are adapted to
perform certain work in the most efficient manner and, accordingly, they may be subdivided into
turning tools, boring tools, milling tools, etc. These tools having one effective cutting edge along
which excess material from the workpiece is removed are known as single-point cutting tools.

3.Other tools removing excess material on two or more cutting edges simultaneously are known
as multipoint cutting tools. Each cutting tool consists of a shank for holding the tool in the
machine and a cutting edge for removing chips from the work.

4. It is known that cutting tools used for longitudinal turning and subdivided into roughing tools
and finishing tools. Ranging tools are applied for roughing or removing the excessive metal from
the work. Such tools usually have a long cutting edge. Finishing tools are used after the work has
been turned with a roughing tool to give accurate size and clean surface to the work being
machined.
