Cutting

• Cutting represents a set of processes in which the workpiece is brought to a specified geometry by removing excess material. This operation is carried out using various types of tools that come into a finished part that meets the required characteristics. Two products are the net result of cutting: the waste or excess material and the finished part.

Tipes of cutting

• Laser cutting
• Water cutting
• Blade cutting
• Spark machining-EDM

Molding

molding is the proces of changin the shape of a material

there are diferent tipe of molding

• Dip molding
• Blow molding
• Vaccum molding
• Compresion molding
• Injection molding
• Rotomolding

Casting

Casting is a historic molding technique with a 6,000-year history, involving pouring a liquid material into a mold to create a desired shape. The material then cools and solidifies, resulting in a casting that is removed from the mold. Common materials include metals, epoxy, concrete, plaster, or clay. This method is favored for crafting intricate shapes that are challenging or expensive to produce using other methods. The oldest evidence of casting dates back to 3200 BC, exemplified by a copper-cast frog, showcasing the early use of intricate casting patterns by our ancestors

Powder bed fusion

Powder Bed Fusion (PBF) 3D printing is a precise manufacturing technology that utilizes a heat source, typically laser or electron beams, to fuse powder particles layer by layer, creating geometrically complex products with precision.

Material jetting

Material Jetting in 3D printing is akin to 2D ink-jetting. It uses photopolymers, metals, or wax that solidify under light or heat, building physical objects layer by layer, similar to stereolithography. This technique enables the printing of diverse materials within the same part.

Binder jetting

Binder Jetting 3D printing involves applying a binding agent onto thin layers of powdered material to solidify it.

Material extrusion

Material Extrusion 3D printing utilizes a continuous filament of thermoplastic material fed through a heated extruder. The molten material is extruded onto a heated platform for adhesion, layer by layer. Computer control guides the extruder head's movement for precise deposition, creating a growing 3D workpiece.

Vat photopolimeritaton

Photopolymerization 3D printing involves a liquid photopolymer in a vat selectively cured by a heat source. This process builds a 3D object layer by layer until completion

DLS 3D printing, or Carbon DLS, employs digital light synthesis to map printed parts. This additive manufacturing method uses light to initiate a curing process with heat, resulting in the desired material properties for the finished product.

Milling

Milling is a subtractive machining process employing machine tools to precisely cut materials like metals, plastics, or wood into specific geometrical parts. Utilizing 3- or 5-axis processes, milling machines quickly produce end-use parts.

Lathe

Lathes play a crucial role in manufacturing, removing material from workpieces, be they wood or metal. These machines securely hold the workpiece, causing it to rotate against a stationary cutting tool for precision alterations.

Drilling

Drilling is a cutting process where a drill bit is spun to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute.

Forming

Forming operations are categorized based on effective stress differences, with a focus on compressive loading. Compressive forming includes processes such as:

• Rolling: Material passes through a pair of rolls.
• Extrusion: Machine pushes material through an orifice.
• Die forming: Press stamps material around or onto a die.
• Forging: Localized compressive forces shape the material.
• Indenting: Tool is pressed into the object.

Forging

Forging, a metal manufacturing process, utilizes compressive forces from a hammer, often a power hammer or die, delivering a "blow." The process is categorized by temperature—cold, warm, or hot forging—wherein metal is heated at elevated temperatures, typically in a forge.

• Modern industrial forging employs presses or hammers powered by compressed air, electricity, hydraulics, or steam. These are not ordinary hammers, featuring reciprocating weights in the thousands of pounds. In artistic smithies, smaller power hammers have weights of 500 lbs (230 kg) or less, while hydraulic presses are standard. Steam hammers, although mostly obsolete, still find minimal use due to the advancement of more convenient and powerful tools

Punching

Punching involves using a stamping press to shape flat sheet metal, sourced as a blank or coil, into a net shape, utilizing a tool and die surface

Welding

Welding is a fabrication process that joins materials, typically metals or thermoplastics, by melting the parts together with high heat and allowing them to cool, resulting in fusion.

Bending

The bending process involves shaping and manipulating thin sheets of metal to create specific components and products. Various techniques such as cutting, bending, and assembly are used to transform the sheet into desired forms, such as electronic device casings, vehicle components, and other products that require sheet metal. This process is crucial in the industry for producing high-precision and durable parts from metal sheets.

Extrusion

The extrusion process can create objects with fixed cross-sectional profiles by pushing a material

Two tipes of extrusion:

• Continuous extrusion: that involves the production of an indefinitely long material
• Semi-continuous extrusio: that involves the production of many pieces.

Sanding

Sanding involves rubbing a material, like a thermoset composite, with an abrasive material to achieve a precise, smooth surface. Sandpaper, a rough and abrasive tool, is commonly used by rubbing it over the composite surface for effective results.
