Sheet forming techniques are used to produce parts from sheet metal with a high surface area to thickness ratio. Common processes include bending, deep drawing, and shearing. Bending operations involve factors like bend radius, anisotropy, and springback. Deep drawing uses punches and dies to form flat sheets into shapes like cups with consistent wall thickness. Shearing separates metal using punches and dies, and burr height depends on factors like clearance and material ductility.
Sheet Metal Operations
Sheet metal operations are cold-working processes that can manufacture low-cost metal parts in high volumes quickly. Sheet metal is metal between 0.006-0.25 inches thick that can be cut, bent, or stretched into various shapes. Common sheet metal operations include embossing to add raised or sunken designs using heat and pressure, coining to add similar impressions to both sides, spinning to shape metal over a rotating mandrel, stretch forming to simultaneously stretch and bend metal over a die, and nibbling which cuts contoured shapes using overlapping slits.

1) UTS of 5052-O aluminum = 280 MPa
2) Thickness, t = 1.8 mm
3) Cutting edge length, L = πD = π * 25 mm = 78.5 mm

Reciprocating pumps
1) Positive displacement pumps work by trapping a fixed amount of fluid and forcing that volume into the discharge pipe, causing the fluid to move in a constant flow.
2) Reciprocating pumps use a piston or plunger that executes a reciprocating motion inside a closed cylinder to push the fluid, with common examples including piston pumps and diaphragm pumps.
3) Diaphragm pumps use a flexible diaphragm and check valves to pump fluids, and can handle corrosive or abrasive liquids since the only parts in contact with the fluid are the valves.

Superplastic forming uses air pressure to form superplastic materials like aluminum alloys into complex shapes at high temperatures. Electroforming produces thin metal parts by electroplating a metal skin onto a mandrel that is later removed. Fine blanking produces finished parts in a single press stroke with cleanly sheared edges. Hydroforming uses high-pressure fluid to form materials like steel into dies while laser forming thermally shapes sheet metal into 3D parts without contact. Powder metal forging fully densifies metal powders in a die to create precise net-shape components.

Coining process
Coining is a cold working process that uses high pressure to plastically deform a workpiece between two closed dies to conform to their shapes. It provides a finer, more detailed surface finish than other processes like stamping. Coining does not require cutting or expensive machinery. It work hardens the surface of the material, making the finished parts more impact and abrasion resistant and eliminating the need for further finishing steps. Industrial applications of coining include minting coins and medals, making jewelry, precision springs, electronic parts, and other complex parts requiring polished surfaces.
Manufacturing processes
1. Forming is a metalworking process that shapes metal by deforming it without removing material. Common forming processes include rolling, extrusion, forging, and die forming.
2. Joining processes like welding, brazing, and adhesive bonding are used to connect metal components together. Welding involves melting materials to join them, while brazing uses a filler metal below the melting point of the base materials.
3. Machining removes material using tools like lathes, mills, drills and grinders to shape a workpiece. It allows for tight tolerances but incurs significant material removal and waste.

Diagrams are also included to illustrate stages of specific processes like impression die forging, thread rolling, and shape rolling. The document contains a comprehensive overview of common bulk deformation techniques for metalworking.
Matels
The document discusses various metal forming techniques including swaging, roll forming, forging, sand casting, die casting, investment casting, metal injection molding, electroforming, centrifugal casting, and press braking. It provides details on their typical applications, related processes, quality considerations, design opportunities, compatible materials, costs, and environmental impacts.
Unit 1 Theory of metal Cutting
It describes about the metal removal procedure from the parent metal to the required shape for assembly & to mate with other parts.
Lo# 3a(2033 common) manufacturing technology PART 1
This document summarizes various metal working processes including hot and cold working. It discusses bulk deformation processes like rolling, forging, extrusion and drawing which involve significant deformation of the starting workpiece. Rolling is described as reducing thickness between two rotating cylinders. Extrusion forces metal to flow through a die to take its shape. Drawing pulls wire through progressively smaller dies. Forging compresses metal between dies to impart shapes. The document also covers sheet metal working processes like bending, drawing and shearing which are performed on metal with a high surface area to volume ratio using punch and die tools.
F O R G I N G & E X T R U S I O N
This document discusses various bulk deformation processes including forging and extrusion. It describes different forging techniques like open-die, closed-die, and impression-die forging. Extrusion involves forcing a heated billet through a die to produce a part. Key factors that affect forging and extrusion are discussed, such as die design, temperature, speed, and the extrusion ratio. Common defects and parts produced via these processes are also mentioned.
Mechanics of Chip Formation - Unit of MFT
The document discusses material removal processes and machining. It covers various machining operations like turning, drilling, boring, and milling. It describes the fundamental process of orthogonal cutting and factors that influence the cutting process like cutting speed, depth of cut, feed, cutting fluids, tool angles, chip types, and tool wear. Continuous chips result in good surface finish and tool life while discontinuous chips are easier to dispose but can cause vibration. Proper selection of factors like material, cutting speed, and rake angle can produce different chip types.
Deep drawing
This document provides information about deep drawing and sheet metal forming equipment. It discusses the history and definition of deep drawing, the mechanics and process of drawing, types of deep drawing stations like blanking, drawing, piercing and trimming. It also describes the metal flow during drawing, recommended tool materials, lubrication and cooling methods, common defects, advantages and disadvantages of deep drawing. Different applications of deep drawing in Pakistani industry are highlighted. Comparisons are made between deep drawing and superplastic forming. Finally, various metal forming tools and types of forming dies are explained.
3 CASTING SECOND LECTURE.ppt

This document provides a syllabus for an advanced manufacturing processes course. The syllabus covers 6 units: 1) metal forming processes, 2) advanced welding, casting and forging, 3) advanced material processing techniques, 4) micro machining processes, 5) additive manufacturing processes, and 6) measurement techniques for micro machining. Some key processes discussed include roll forming, hydroforming, electromagnetic forming, friction stir welding, vacuum die casting, and additive manufacturing methods like powder bed fusion. Contact information is also provided.
Manufacturing Processes
This PPT is useful for First Year of Engineering Students and faculties as well as Mechanical Engineering Students.
Flashless forging
This document discusses flashless forging, a near net shape forging process where metal is compressed in a die cavity without any excess flash. Flashless forging provides benefits over closed die forging such as material and energy savings from eliminating flash, higher production rates due to no trimming, and better part dimensions and grain structure. While it enables net shape parts and savings, flashless forging also requires more complex dies and strict control over blank weight and temperature compared to conventional forging.
Unit 3 manufacturing process3
The document discusses various manufacturing processes including casting, machining, surface finishing, metal forming, sheet metal working, and metal joining processes. It provides details on the key steps for processes like casting such as pattern making, molding, melting, pouring, and cleaning. It also describes different types of casting like sand casting and die casting. Other metal forming processes discussed include forging, extrusion, and sheet metal working techniques like bending and punching.

- 6. Stamping Includes a variety of operations, such as punching, blanking, embossing, bending, flanging, and coining; simple or complex shapes formed at high production rates; tooling and equipment costs can be high, but labor costs are low.
- 7. Superplastic forming Complex shapes, fine detail, and close tolerances; forming times are long, and hence production rates are low; parts not suitable for high- temperature use.
- 8. MAGNETIC- PULSE FORMING Shallow forming, bulging, and embossing operations on relatively low-strength sheets; most suitable for tubular shapes; high production rates; requires special tooling.
