What is the differences between products made of sheet metal and those made by casting and forging?
The material can be similar however the process defines the grain structure and physical properties of the metal. Forging shapes hot metal by compressive force, casting is performed by pouring molten material into a molded shape and sheet metal is produced by rolling through presses until the desired thickness is achieved. The desired end result determines the process utilized. Extruding is also a process to produce a different result.
What is the use of miller machine?
He (or she) mills that is turns grain into flour
What direction does water flow through a universal pipe joint?
every direction its all pressurized every direction its all pressurized
What is axial direction?
It is the direction in line with (parallel to) the axis of the part. If you have a cylindrical shaft, for example, the axial direction runs along the length thru the center of the circular ends.
What is the significance of the Mechanical Reaper today?
we can harvest grain faster now that we had used this machine
How can I determine the direction of the wood grain for sanding?
To determine the direction of the wood grain for sanding, run your hand over the surface of the wood. The direction that feels smoothest is the direction of the grain. Sand in the same direction as the grain to avoid damaging the wood.
Grain flow in forging?
When metal under goes mechanical working (forging) and deformation takes place, the grains in the metal get aligned in the direction of material flow. When you cut and polish the forging in the direction of material flow and macro etch, the surface will reveal fibre like structure. This is known as grain flow.
What is grain flow in forge component?
Grain flow is a typical grain pattern generated during forging of metal. When a piece of metal is cold or hot forged by applying external force or pressure, then metal starts deforming normal to the direction of application of pressure. During the process of permanent deformation, metal grains get deformed & generate what is known as" flow lines ". This is called Grain Flow. It can be seen by chemically etching cross sectional piece of forge metal shown fig below.
Do you bend metal with the grain?
No, metal does not have a grain like wood does. When bending metal, you would typically consider factors such as the type of metal, its thickness, and the method of bending to achieve the desired result.
What is the grain of the timber?
The grain - is the pattern in the wood, showing the direction of the fibres.
What is the direction that fibers run in wood called?
The direction that fibers run in wood is called the grain. Grain direction is important in woodworking as it affects the strength, stability, and appearance of the wood.
In which direction do you sand wood?
never sand wood across the grain always sand with the grain
Which direction do you sand wood?
never sand wood across the grain always sand with the grain
How does the direction of the grain affect the strenght of a place of timber?
The direction of the grain in timber significantly impacts the strength of the wood. Wood is strongest along the grain, so a piece of timber with the grain running parallel to the load will be stronger than if the grain runs perpendicular to the load. This is because the fibers in the wood provide more support and resistance to forces acting along the grain.
What is the tolerance for grain direction?
You should determine the tolerance for grain direction, including secondary grain direction if you have a single crystal material. You should evaluate it's effects on your structures harmonics and stress to see which gives you the most favorable results, then see how far you can deviate from that and still have acceptable life.
What is a grained paper?
Most paper has what we call a "grain direction"; it used to be thought that the grain direction was due to paper fibers being aligned in that direction in the paper-making process, but current thinking is that it is more strongly related to what tension the paper was under as it dried. Handmade papers which were dried between felts often do not have a pronounced grain direction. When a paper does have a pronounced grain direction, as most modern machine-made papers do, it will bend or fold more easily with the grain than across it. If you dampen one side of such a paper, it will curl into a tube with the grain. Most commercial papers are sold "grain long" -- that is, the grain runs the long way, from top to bottom on the sheet. (Putting these things together, if you take a sheet of commercial US printer paper and dampen it on one side, it'll curl up with the grain, resulting in an 11-inch-long tube.)
How grain size depends on the temperature of liquid metal?
It doesn't, it depends on how fast the metal was cooled.
