Chapter 6 - Bulk Deformation Processes

Bulk deformation processes create parts without removing material.
Forging: Produces discrete parts using dies; typically high temperature, moderate to high labor cost, moderate to high operator skill; common for casting and powder metallurgy techniques.
Rolling Processes: Creates flat sheets, plates, and foil at high speeds, with good surface finish. Requires high capital investment, low to moderate labor costs, and moderate operator skill. Shapes various structural forms (I-beams and rails) at high speeds using shaped rolls. Requires high capital investment, low to moderate labor costs, and moderate operator skill.
Extrusion: Makes long lengths of solid/hollow products with consistent cross-sections; often performed at elevated temperatures; product is then cut to length; can compete with roll forming; similar to forging. Moderate to high die and equipment cost, low to moderate labor cost, and low to moderate operator skill.
Drawing: Creates long rods, wires, and tubes with round (or other) cross-sections, smaller cross-sections than extrusions; good surface finish, low to moderate die, equipment, and labor costs, and low to moderate operator skill.
Swaging: Radial forging of discrete or extended parts with various internal and external shapes; typically at room temperature; low to moderate operator skill.
Forging Steps:
1. Prepare slug (saw, cut, share); clean surface (shot blast, flame)
2. Heat and descale (oxide layer)
3. Lubricate (oil, soap, glass, graphite)
4. Forge
5. Remove flash, trim, machine, grind
6. Check Dimension
7. Post-process (if necessary)
Open Die Forging (Upsetting): The workpiece takes the shape of the die cavity with forces between two shaped dies; often carried out at elevated temperatures for increased ductility.
Closed Die Forging: The workpiece shapes to the cavity while being forged, often between two dies; elevated temperatures for enhanced ductility.

Chapter 7 - Sheet Forming

Workpiece material comes in coils or sheets/plates.
Sheet-metal forming: press working, press forming, stamping. Plates > 0.6mm, Sheets ≤ 0.6mm.
Roll Forming: Long parts with constant complex cross-sections; good surface finish; high production rates; high tooling costs.
Stretch Forming: Large parts with shallow contours; suitable for low-quantity production; high labor costs; tooling and equipment depend on part size.
Drawing: Shallow or deep parts with relatively simple shapes; high production rates, high tooling and equipment costs.
Stamping: Variety of operations, like punching, blanking, embossing, bending, flanging, and coining; produces simple or complex shapes; high production rates; medium to high tooling and equipment costs; low labor costs.
Rubber-pad forming: Drawing and embossing of simple or complex shapes; sheet surface protected by rubber membranes; flexible; low tooling costs; labor costs are low.
Spinning: Small or large axisymmetric parts; good surface finish; low tooling costs, but labor costs can be high.
Superplastic forming: Complex shapes; fine detail; close tolerances; long forming times; low production rates; requires high labor costs; not suitable for high-temperature applications.
Peen Forming: Shallow contours on large sheets; flexibility of operation, high equipment costs, suitable for low-quantity production, process used for straightening parts.
Explosive Forming: Large sheets with relatively complex shapes, especially axisymmetric; low tooling costs; high labor costs; suitable for low-quantity production.
Magnetic-pulse forming: Shallow forming, bulging, and embossing operations on low strength sheets; suitable for tubular forms; high production rates; require special tooling.
Important factors: Elongation, Yield Point Elongation, Anisotropy, Grain Size, Residual Stress, Spring Back, and Wrinkling.

Chapter 8 - Machining

Machining (material removal) uses mechanical energy.
Cutting: Turning, boring, drilling, tapping, milling, sawing, broaching.
Abrasive: Grinding, honing, lapping, ultrasonic machining.
Non-conventional (advanced) machining: Electrochemical machining, laser beam machining, electrical discharge machining, water-jet machining.
Machining variables: Independent - Tool material and conditions, tool geometry, workpiece material, cutting conditions (speed, feed, depth), type of cutting fluid, tool holders, fixings. Dependent - Type of chip, force required, energy dissipated, temperature rise, tool wear, surface finish.
Chip Morphology (type of chips produced): Continuous, Discontinuous.
Lathe Operations: Straight turning, taper turning, profiling, facing, face grooving, cutting with a form tool, internal boring.
Turning Operations: Depth of cut, feed, cutting speed, torque. Material Removal Rate (MRR).
Milling Operations: Peripheral (slab), face, end milling.

Chapter 9 - Nontraditional Machining

General information about Nontraditional Machining.
Types of Nontraditional Machining: Ultrasonic Machining (UM), Chemical Machining (CM), Electrochemical Machining (ECM), Electrochemical Grinding (ECG), Electrical Discharge Machining (EDM), Wire EDM, Laser Beam Machining (LBM), Electron Beam Machining (EBM), Water Jet Machining (WJM).
