Very ductile material will often smear rather than cut during machining operations. Less ductile material (more brittle) will cut more easily.
Undercutting of gears, is machining a matched set of dogs/slots that grip into each other - so that they will grip harder the more torque the engine is providing. This will prevent the gears from slipping out again after initially having them engaged. An easy setup, is to fix the gear with its axis center offset in an indexing head - sligthly tipped over(3 to 5 degrees - depending on how much material that can be removed, or how badly the dogs are worn), so that the actual dog to be machined spins precisely around its own vertical axis when table is turned. The finished dog, will have a uniform shape all the way around its contact areafacing the slots/dogs of the interacting gear next to it.Usually done in a vertical mill, by grinding - or with a dovetail milling bit. Using a dove tail milling bit, will let the machinist fix the gear in a horizontal position, rather than having to tilt it the neccessary amount of degrees. Dogs, slots - or teeth, need to be hardened again, if they are ground beyond the limit of the previous hardened surface of the material.
1. Jaw plates are reversible. 2. Broken particle size uniformity, crushing ratio of high efficiency. 3. Less noise, dust, easy to operate. 4. Well-designed, easy to operate.
Dr Dee of Yale ;well, this is very complicated to answer, so i will put it into easy to answer terms. i dont know.
the answer to your question is easy the simple machine a wagon wheel is a wheel and axel

Timber is very strong and can be used for structural building. It is very easy to use and it is very useful.
Yes, they are easy to bend, and are thus ductile.
it is not easy to weld hard materials....it always difficult to hard materials.....
There would be fire safety concerns when machining a highly combustible metal, such as magnesium. Machining can produce significant heat in the material being machined, and produces a waste product such as lathe turnings, chips or dust that is very easy to ignite. This results in a Class D fire, and standard ABC rated extinguishers are ineffective in extinguishing such as fire.
Gold (Au) is a highly soft precious metal. Ductility refers to its malleability, that is its easy in shaping. Pure gold is highly ductile, and for this reason jewelry forms use harder gold alloys using other metals as hardeners.
* Ductile: this is material which have ductility as a property.* Ductility: the property of a material to be deformed by tensile stress; this material can form easy wires.* Malleability: the property of a material to be deformed by compressive stress; this material can form easy foils.* Conductivity: the property of a material to conduct easy electricity or heat.* Shininess: the property of a material to have a luster, to easy reflect light.
It is hard and brittle
Increasing temperature generally decreases the ductility of materials. This is because higher temperatures promote dislocation movements within the material, leading to reduced strength and ductility. At extremely high temperatures, materials can become more prone to deformation and failure.
Iron is malleable and ductile due to its atomic structure that allows its atoms to easily slide past each other when a force is applied. This property makes iron easy to shape into different forms without breaking. Additionally, the presence of impurities such as carbon can also affect the malleability and ductility of iron.
Easy to change the shape of without destroying the integrity, like plasticene, lead, gold
A brittle material is one that fails by fracturing after only a very small amount of plastic strain has occurred. Sandstones tend to be made up of quartz and feldspars which are themselves brittle. However sandstone and many other materials are only thought of as brittle because we are used to dealing or working with them at the pressure and temperature conditions present at the Earth's surface and can actually be either brittle or ductile (significant plastic deformation can occur before ultimate rupture) depending on the temperature, confining pressure and strain rate applied to it. In general at low confining pressures and temperatures (i.e. near the Earth's surface), sandstone will fail in a brittle fashion. However as the temperature and or confining pressure increases it becomes increasingly ductile.
Both Na and K are very 'soft' or ductile (easy malleable) metals.
