Drills are categorized by their material: High-Speed Steel (HSS), High-Speed Steel with Cobalt, and Carbide.

A basic, inexpensive drill material suitable for soft materials like wood and some metals.

A drill material with the highest heat/wear resistance and suitable for the hardest materials.

A hole that completely passes through a material, facilitating fastener use.

A hole that stops short of the material's opposite side; used for hidden fasteners.

The lost motion or clearance between parts in a mechanism.

Milling where the cutter's axis is parallel to the surface being machined, using the cutter's outer edges.

Milling where the cutter's axis is perpendicular to the surface, using both the cutter's ends and outer edges.

Peripheral milling where the cutter extends across the entire width of the workpiece.

Milling a slot as the width of the cutter is smaller than the width of the workpiece.

Face milling where the cutter extends beyond the workpiece on both sides.

Milling with a cutter smaller than the workpiece width, creating a slot.

An automated machine tool that performs multiple machining operations using CNC control with minimal human intervention.

A method of metal shaping using rollers to create a profile in a long strip of metal. High speed and volume.

Heating metal to a soft point and shaping it with air pressure on a single tool.

Sheet metal forming to make cups, boxes, or hollow shapes. A punch pushes the metal into a die.

Used to form or bend shallow sheet metal profiles. High tooling cost, mass production.

A stamping process that creates indentations or raised features in sheet metal like lettering or ribs.

Transforming a flat metal disc into a round shape using a lathe and a roller.

A forming die in metal spinning that gives shape to a metal disc and supports it.

Applies pressure in metal spinning, causing metal to flow over the mandrel.

A laser cutting method where the laser beam provides all the energy needed for cutting, and an inert gas like nitrogen expels molten material from the kerf.

A laser cutting method where the laser beam is assisted by chemical reactions from oxygen used as a cutting gas.

A high-precision laser cutting technique that minimizes melting by vaporizing material, resulting in very clean edges. It also involves shielding the cutting area from oxidation using an assist gas.

Laser cutting offers several advantages, including high cutting speeds, a small heat-affected zone, accurate profiling, smooth cutting finishes, and no cutting forces on the workpiece.

Laser cutting also has some disadvantages, including high capital equipment cost, higher operating costs due to consumables (gases), and a potential safety hazard from the laser and vaporized material.

A casting defect where the molten metal fails to fill the entire mold cavity, often due to rapid cooling and solidification of the metal.

A rounded corner used to smooth transitions between different sections of a casting, reducing stress concentrations.

A manufacturing process where molten metal is poured into a permanent mold (die) to produce precise castings.

A type of die casting where gravity is used to fill the die with molten metal.

Gravity die casting is suitable for producing medium to high volume parts made from non-ferrous alloys like aluminum, zinc, and copper.

A casting method that uses pressure (around 2-5 bar) to fill molds with molten metal, instead of relying solely on gravity.

A casting method that uses very high pressure (up to 2,000 bar) to inject molten metal into a mold. It's known for producing parts with very thin walls and excellent surface finish.

Gravity die casting offers advantages such as better dimensional accuracy, smoother surface finish, improved mechanical properties, thinner wall capabilities, and faster production times.

While gravity die casting offers benefits, it also has some disadvantages, such as limited design flexibility, high initial investments, and longer lead times.
