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, paperclips are made of a ductile material, typically steel. Ductility is a property that allows a material to be stretched or bent without breaking. This property is essential for the flexibility and utility of paperclips.
Which material easy to break?
Glass is a material that is easy to break due to its brittle nature and lack of flexibility. It can shatter into sharp pieces when subjected to stress or impact.
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.
What wires in a ciruit are made of material that is a doortuccn?
Copper wires are commonly used in circuits as they are a good conductor of electricity. Copper is a ductile material that allows easy shaping into wires and has low resistance, making it ideal for carrying electrical current efficiently in a circuit.
What are the key considerations when creating a lathe template for precision machining?
When creating a lathe template for precision machining, key considerations include selecting the appropriate material, ensuring accurate measurements, designing for stability and rigidity, and incorporating features for easy setup and alignment. Additionally, considering the tooling and cutting parameters is crucial for achieving precise and consistent results.
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
Is an element that are soft and easy to cut cleanly with a knife likely to be a metal or a nonmetal?
An element that is soft and easy to cut cleanly with a knife is more likely to be a metal. Metals tend to have metallic bonds that allow layers of atoms to slide past each other easily, making them malleable and ductile. Nonmetals are usually brittle and cannot be easily cut with a knife.
Why is iron malleable and ductile?
Malleabilty and ductility are properties stemming from how metals bond on a molecular level. Covalent and metallic bonds allow molecules to flex, before breaking. As opposed to ionic bonding, which is sensitive to being bent; ionic bonds are brittle
