CHAPTER-17-INDUSTRIAL MATERAIALS AND PROCESSES.pptxNicaJoySunga
Industrial materials and processes encompass a wide range of materials, such as metals, plastics, ceramics, and composites, utilized in manufacturing various products. These materials undergo specific industrial processes like casting, molding, machining, welding, and forging to transform raw materials into finished goods. Understanding and optimizing these materials and processes are crucial for ensuring product quality, efficiency, and cost-effectiveness in industrial production.
Modeling and Analysis of Progressive Tool with Pilot LocationIJERA Editor
Press tool components play an important role in every aspects of modern word. There are different types of press tools are available, in this progressive tools are more influence the automobile industry for mass production. The operation of a progressive die involves the series of sheet metal operations at two or more stations during each press stroke for developing the complete work piece. The strip must move from the first station through each succeeding station and perform one or more distinct die operations at each working station. One or more idle stations may be incorporated in the die. In this paper we use software CATIA V5 for modeling a progressive tool to manufacture a washer for M12 bolt. In earlier design there is no primary stopper for first station and there are no accurate location like pilots for further station. In this design we provide primary stopper for first station, pilots for further stations and also we replace the die block with die buttons. For this any damage occurs on die button simply we can replace that particular die button instead of replacement of entire die block this will reduce the material cost, machining time and die maintenance.

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

2. Press working may be defined as, a
manufacturing process by which various
components are made from sheet metal. This
process is also termed as cold stamping. The
machine used for press working is called a
press.
10/29/2017 8:21 AMRAP
3. Press operations are broadly classified in to two
groups:-
• Cutting operations,
• Non cutting operations (Forming operations)
10/29/2017 8:21 AMRAP
5. 1: Blanking:
Blanking is the operation of
cutting a flat shape from sheet metal.
The product punched out is called the
“blank” and the required product of
the operation the hole and the metal
left behind is discarded as waste.
2: Punching or Piercing:
It is a cutting operation by
which various shaped holes are made
in sheet metal. Punching is similar to
blanking except that in punching, the
hole is the desired product. The
material punched out from the hole
being waste.
10/29/2017 8:21 AMRAP
6. 3: Trimming:
This operation consists of cutting
unwanted excess of material from the
periphery of a previously formed
component.
4: Shaving:
The edge of a blanked part are
generally rough, uneven and un square.
Accurate dimensions of the part are
obtained by removing a thin strip of metal
along the edges.
10/29/2017 8:21 AMRAP
7. 5: Notching:
This is cutting operation by which metal pieces are cut from the edge
of the sheet , strip or blank.
6: Perforating:
This is a process by which multiple holes are very small and close
together are cut in a flat sheet metal.
7: Slitting:
It refers to the operation of making incomplete holes in a work piece.
8: Lancing:
This is a cutting operation in which a hole is partially cut and then
one side is bent down to form a sort of tab. Since no metal is actually removed
and there will be no scrap.
10/29/2017 8:21 AMRAP
8. 1: Bending:
In this operation; the material in
the form of flat sheet or strip is uniformly
strained around a linear axis which lies in
the neutral plane and perpendicular it’s the
length wise direction of the sheet or metal.
2: Drawing:
This is a process of forming a flat
work piece into a hollow shape by means
of a punch which cause the blank into a
die cavity.
3: Squeezing:
Under the operation, the metal is
caused to flow to all portions of a die
cavity under the action of compressive
forces.
10/29/2017 8:21 AMRAP
10. 1: Bed:
The bed is the lower part of the press frame that serves as a table to which a
Bolster plate is mounted.
2: Bolster Plate:
This is a thick plate secured to the press bed , which is used for locating
and supporting the die assembly. It is usually 5 to 12.5 cm thick.
3: Die Set:
It is unit assembly which incorporates a lower and upper shoe, two or more
guide parts and guide part bushings.
4: Die Block:
It is a block or a plate which contains a die cavity.
5: Lower Shoe:
The lower shoe of the a die set is generally mounted on the bolster plate of
a press. The die block is mounted on the lower shoe, also the guide post are mounted
on it.
10/29/2017 8:21 AMRAP
11. 6: Punch :
This is male component of a die assembly, which is directly or indirectly
moved by and fastened to the press ram or slide.
7: Upper Shoe:
This is the upper part of the die set which contains guide post bushings.
8: Punch Plate :
The punch plate or punch retainer fits closely over the body of the punch
and holds it in proper relative position.
9: Back up Plate:
Back up plate or pressure plate is placed so that intensity of pressure
does not become excessive on punch holder. The plate distributes the pressure
over a wide area and the intensity of pressure on the punch holder is reduced to
avoid crushing.
10: Stripper:
It is a plate which is used to strip the metal strip from cutting a non-
cutting Punch or die. It may also guide the sheet.

17. The travel for the penetration of the punch, progresses in
three zones:
1. Compression
2. Shearing
3. Breakage
10/29/2017 8:21 AMRAP
18. If ‘t’ is the total travel of the punch in the sheet thickness,
then ‘t’ can be expressed as –
Where,
a= Punch progression responsible towards compression;
around 10 – 30 % of ‘t’,
b= Punch progression responsible towards true shearing;
around 40 – 80 % of ‘t’,
c= Punch progression responsible towards breakage;
around 10 – 30 % of ‘t’,
t = a+b+c
10/29/2017 8:21 AMRAP
19. The ratio b/t is known as “Percentage Penetration” and denoted by ‘k’.
Then shear force requirement:-
Shear Force = Failure stress X Area under cutting
= Ultimate shear stress X Peripheral length of punch X Thickness
of material X % Penetration
Shear Force = u.s.s. X π.d X t X k (For a circular punch)
This expression can be used to calculate press capacity.
The factor k depends on:
1. Work piece material
2. Thickness of stock
3. Clearance between die and punch
10/29/2017 8:21 AMRAP
20. Punching Blanking
The difference in dimensions between the mating members of a die set is
called clearance. This clearance is applied in following manner:
1: when the hole has to be held to size i.e. the hole in the sheet metal is to be
accurate (punching operation) , and slug is to be discarded. The punch is made to
the size of the hole and the die opening size is obtained by adding clearance to the
punch size.
2: In blanking operation , where the slug or blank is the desired part and has to be
held to size, the die opening size equals the blank size and the punch size is
obtained by subtract.
