Study Notes
Machining Technology
- Machining is the process of shaping materials using machine tools. It involves reducing or finishing materials by techniques like turning, shaping, planing, or milling. Essentially, it's using tools to cut materials to desired sizes and shapes.
1.1 Introduction
- Machining technology significantly impacts manufacturing and various industries. Advancements continue to improve processes.
1.2 Machine Tools
- Machine tools have evolved from primitive forms to advanced technologies, achieving precision and efficiency. Initially powered by people, animals, or water/steam, they now primarily use electricity.
1.2.1 History of Machine Tools
- Humans have long used machine tools. Early tools were simpler, while modern tools offer greater precision and efficiency.
1.2.2 Standard Machine Tools
- Standard machine tools are commonly used power-driven metal cutting or forming machines for specific applications. These tools have improved and evolved from hand-held and hand-powered tools.
- Drill Press - A device used primarily for creating round holes in materials, providing greater power and control than hand-held drills.
- Engine Lathe - A versatile and highly useful tool for machining and shaping materials. Its main functions focus on holding and rotating workpieces while using cutting tools to produce cylindrical parts, and various operations can be carried out on it.
- Milling Machine - Primarily for creating flat and angled surfaces by moving the workpiece into a rotating cutter to remove material.
- Sawing Machine - Uses multiple-tooth blades for cutting and includes various types such as power hacksaws, band saws, abrasive cut-off saws, and cold saws.
1.3 Benefits of Technology in Machining
- Advancements in machining technology have broad benefits including but not limited to:
- Aerospace, automotive, and motorsport industries rely heavily on machining for precise gear, wheel, engine, drive train components, and other parts.
- Medical industries utilize machined instruments in high-tech surgery, including artificial hearts.
- Durable goods like hardware, glass, and metal products are created using machining processes.
- Consumable goods, including clothes, paper, plastic packaging, and food, are shaped using food molding.
