Study Notes
Machining Technology
- Machining is the process of shaping materials using machine tools. Specifically, it involves reducing or finishing materials by using tools to cut them.
Introduction to Machining
- Humans have used machine tools for centuries, evolving from primitive tools to sophisticated, precisely efficient, technologically advanced tools.
- Earlier machine tools were powered by humans, animals, water, or steam.
- Modern tools use electricity.
Standard Machine Tools
- Common machine tools include drill presses, engine lathes, milling machines, and sawing machines.
- These tools are used to perform various metal cutting and shaping operations.
- Some are power-driven and used for shaping metals.
- Others are improved versions of older hand-powered tools.
- Some implement entirely new technologies for precision and efficiency.
Drill Press
- A drill press, or drilling machine, is a machining method.
- Primarily used to create round holes in materials.
- It is more powerful and controllable than hand-held electric drills, due to the greater power provided.
Engine Lathe
- An engine lathe is a versatile and historically significant machine tool.
- The main function of a lathe is to rotate a workpiece and shave away material using cutting tools, generating cylindrical parts.
- Common operations include turning, tapering, facing, drilling, boring, reaming, and thread cutting.
Milling Machine
- A milling machine creates flat and angled surfaces by moving a workpiece into a rotating cutter to remove material.
- It works by moving the rotating cutter across a part to remove material.
- It can create very precise flat surfaces as well as complex curves and angles, with both conventional and CNC/computer numerical control versions available today.
Sawing Machine
- Sawing machines utilize multi-tooth blades to cut materials.
- Various types of sawing machines are used, including power hacksaws, band saws, abrasive cut-off saws, and cold saws.
- Power hacksaws are the most common type used in workshops.
Benefits of Machining Technology
- Machining is crucial in many industries, including aerospace, automotive, and motorsports.
- It's used to create precisely shaped parts like gears, wheels, bolts, nuts, engines, drive trains, and others.
- Medical devices also heavily rely on machining.
- Durable goods also rely on machining, such as hardware, glass, metal products, and even some types of food packaging.
