Why the machining of brittle material is easy than ductile material?

Very ductile material will often smear rather than cut during machining operations. Less ductile material (more brittle) will cut more easily.

What is undercutting of gears?
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.

Is timber a ductile or brittle?
Timber is very strong and can be used for structural building. It is very easy to use and it is very useful.
Are paperclips ductile?
Yes, they are easy to bend, and are thus ductile.
Why it is eassy to weld hard material than ductile?
it is not easy to weld hard materials....it always difficult to hard materials.....
What material has fire safety concerns associated with machining?
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.
What is the malleability for gold?
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.
What does the term ductility and thermal conductivity mean?
* 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.
Is bronze easy to bend?
It is hard and brittle
What is the effect of temperature on ductility?
At very low temperatures, ductile materials go through a transition to brittleness - above this point they are more ductile and at their highest toughness, below this point they are brittle and have very low toughness (they simply shatter). The best example of this is the classic liquid nitrogen demo - take something that is easy to damage but can be deformed or torn (a flower petal is what I saw, paper probably works too, or a leaf), dip it in liquid nitrogen, drop it, and it will shatter. This effect also works for steel and all kinds of other ductile materials - though the forces needed to shatter it are such that it's not really safe to get close enough to see.Other than the ductile brittle transition effect, I have no idea.Source: My materials engineering course
What are ductile substanes?
Easy to change the shape of without destroying the integrity, like plasticene, lead, gold
Would quartzite or sandstone break more easy?
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.
Why are Na and K called waxy solids?
Both Na and K are very 'soft' or ductile (easy malleable) metals.
What are the Meaning of flexible?
Capable of being flexed or bent; admitting of being turned, bowed, or twisted, without breaking; pliable; yielding to pressure; not stiff or brittle., Willing or ready to yield to the influence of others; not invincibly rigid or obstinate; tractable; manageable; ductile; easy and compliant; wavering., Capable or being adapted or molded; plastic,; as, a flexible language.
