Study Notes

Machining Technology

Machining is a process of shaping or reducing materials using machine tools. It involves cutting materials to desired sizes and shapes.
Machining is crucial in various industries, including aerospace, automotive, and medical.
Technologies in machining are constantly improving, impacting people and manufacturing.

Machine Tools

Machine tools are used for shaping and cutting metal.
They are categorized as either conventional or Computer Numerical Control (CNC) types.
Standard machine tools include Drill Press, Engine Lathe, Milling Machine, and Sawing Machine.

Drill Press

Drill presses are mechanical devices, primarily used to create round holes in workpieces.
They offer more power and control compared to hand-held drills.
They come in various styles and sizes, depending on the task.

Engine Lathe

Engine lathes are versatile tools used in machining.
The main operation involves holding and rotating a workpiece against a cutting tool.
The tool moves along the workpiece to shave material, creating cylindrical shapes.
Common operations include turning, tapering, facing, drilling, boring, reaming, and thread cutting.

Milling Machine

Milling machines are primarily for creating flat and angled surfaces on workpieces.
Rotating cutters move across the workpiece to remove material.
CNC versions of milling machines also allow for curved and contoured cuts.

Sawing Machine

Sawing machines, using multi-tooth blades, cut materials precisely.
Common types include power hacksaws, band saws, abrasive cut-off saws, and cold saws.
Power hacksaws are widely used in workshops.

Benefits of Technology in Machining

Machining technology is crucial for various modern industries.
Precision machining allows for the manufacture of parts for aerospace, automotive, and motorsport industries.
Machining is essential in creating medical devices, including artificial hearts.
Machining makes durable goods and consumable products like clothing, glassware, metal cans, and food.
