| Question | Answer |
|---|---|
| Industrial Processes | Methods of shaping and modifying materials into useful products. |
| Forming | Shaping materials by deformation without removing material, using compressive, tensile, or shear forces. |
| Casting | Pouring molten material into a mold cavity, where it solidifies to form the desired shape. |
| Machining | Controlled removal of material using cutting tools to achieve high precision and surface finish. |
| Finishing | Improving the surface quality or protection of a workpiece. |
| Welding | The process of joining two or more metal parts by melting and fusing them together, with or without a filler material. |
| Rolling | A forming process that reduces thickness by passing material between rollers (e.g., sheets, beams, rails). |
| Forging | A forming process that shapes material by hammering or pressing (open-die and closed-die forging). |
| Extrusion | A forming process that forces material through a die to form profiles (e.g., pipes, rods, window frames). |
| Drawing | A forming process that pulls material through a die to reduce its diameter. |
| Sand Casting | A casting process using sand molds; low cost and versatile, used for engine blocks and machine parts. |
| Die Casting | A casting process where molten metal is forced into steel molds under high pressure, used for automotive parts and appliance housings. |
| Investment Casting (Lost Wax) | A casting process using a wax pattern coated with ceramic, then melted out for precise molds; used for turbine blades, jewelry, and medical instruments. |
| Centrifugal Casting | A casting process where molten metal is poured into a rotating mold, used for pipes, rings, and bushings. |
| Turning | A machining process that shapes a workpiece by rotating it on a lathe. |
| Milling | A machining process that cuts material using a rotating tool. |
| Drilling | A machining process used to produce round holes. |
| Reaming | A drilling variation that enlarges and improves hole accuracy. |
| Boring | A drilling variation that enlarges existing holes for precision. |
| Grinding | A machining process using a rotating abrasive wheel to produce fine surface finishes and maintain tight tolerances. |
| Cutting Speed (Surface Speed) | The speed at which the cutting edge of the tool moves relative to the workpiece surface. |
| Feed (Tool Advance per Revolution) | The distance the tool advances for each rotation of the workpiece (turning) or per tooth (milling). |
| Depth of Cut | The thickness of the material layer removed in a single pass. |
| Power Requirements | The energy needed to perform a cutting operation, influenced by speed, feed, and depth of cut. |
| Polishing | A finishing process that smooths surfaces by abrasion using fine grit. |
| Buffing | A finishing process using a soft wheel with compound to achieve a mirror-like finish. |
| Lapping | An ultra-precise finishing process that rubs the workpiece against a surface with abrasive slurry. |
| Coating | A layer of material applied to a workpiece surface to enhance appearance, corrosion resistance, wear resistance, or other functional properties. |
| Electroplating | A coating process that deposits a thin metal layer (e.g., nickel, chrome) for protection or aesthetics. |
| Anodizing | A coating process that creates an electrochemical oxide layer on metals (e.g., aluminum) for corrosion resistance and color. |
| Arc Welding | A welding process that uses an electric arc to melt metals at the joint (e.g., structural steel fabrication, pipelines). |
| Gas Welding | A welding process that uses a flame from combustible gases (e.g., oxy-acetylene) to melt metals. |
| Resistance Welding | A welding process that uses heat generated by electrical resistance to join metals under pressure. |
| Brazing | A joining process using a filler metal that melts above 450°C to bond base metals without melting them; produces stronger joints than soldering. |
| Soldering | A joining process using a filler metal that melts below 450°C, ideal for delicate joints or heat-sensitive components. |
| Additive Manufacturing (3D Printing) | A process of creating objects by building them layer by layer from a digital model, as opposed to removing material. |
| Porosity (Casting Defect) | Small voids or air pockets inside a cast metal. |
| Shrinkage | Cavities or depressions in a casting caused by uneven cooling. |
| Chatter | Vibrations during cutting that leave uneven surfaces on a machined workpiece. |
| Tool Wear | The deterioration of cutting tools, affecting surface finish and accuracy. |
| Cracks (Welding Defect) | Fractures in the weld or heat-affected zone. |
| Porosity (Welding Defect) | Gas bubbles trapped in the weld metal. |
| Quality Control | The systematic process of inspecting and testing products to ensure they meet specified dimensions, tolerances, and material properties. |
| CMM (Coordinate Measuring Machine) | A quality control tool for automated measurement of complex geometries. |
| Non-Destructive Testing (NDT) | Methods (e.g., ultrasonic, radiography, dye-penetrant) used to detect internal or surface defects without damaging the part. |
