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 the difference between allowance and tolerance in engineering graphics?
Tolerance is unintended deviance from basic size, while Allowance is intended.
What is the schmid factor?
The Schmid factor m is part of the equation for the critical resolved shear stress τ0. The critical resolved shear stress is the component of shear stress in a slip plane, resolved in the direction of slip, necessary to initiate slip in a grain (plastic deformation in metals). m = cos(κ)cos(λ) ; τ0 = mσ κ - the angle between the applied load direction and the slip plane normal. λ - the angle between the applied load direction and the slip direction. σ - the applied stress or load
Engineering drawing standard - BS308 and BS8888?
Please show examples of "++"tolerance feature
What is clearance and tolerance?
Clearance is how much space there is between two or more objects. Tolerance is how much of something an object can withstand before something undesirable happens. NOTE: My examples use random numbers and may not reflect actual clearance/tolerance levels of their real life objects. Also, the undesirable effects may be a bit exaggerated Example - Clearance: The bridge has a clearance of 15 feet. What ever is passing under the bridge will need to be less than 15 feet in order to not hit the bridge. Example - Tolerance: Your computer has a temperature tolerance of 100 degrees. Your computer will need to stay under 100 degrees or damage may occur to the components. The front door on your house is 1 foot by 2 foot and has a size tolerance of 1 micron. Anything larger and it won't close. Anything smaller and there will be a gap between the door and the frame. Either way the killer mosquitoes get in!!!
Can a reference dimension on an Engineering drawing be toleranced?
No, then it would not be a reference dimension. Reference dimensions by definition have no tolerance.
What is metal grain direction?
Metal Grain Direction is similar to Wood Grain Direction. It is the direction in which the metal was produced, so when you look at it under a magnifying glass and see lines, that is the direction in which the metal was made in the factory.
What are tolerance?
unilateral tolerance is a process of giving tolerance in one direction only ex if 10 is the basic dimension then the unilateral tolerances for it an be -0.007 or -0.004 etc..... but should be inthe same direction
What are unilateral tolerance?
unilateral tolerance is a process of giving tolerance in one direction only ex if 10 is the basic dimension then the unilateral tolerances for it an be -0.007 or -0.004 etc..... but should be inthe same direction
What is the grain of the timber?
The grain - is the pattern in the wood, showing the direction of the fibres.
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
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.)
What is a grain of fabric?
A grain of fabric refers to the direction of the threads in the fabric. Fabrics have three grains: lengthwise grain (parallel to the selvage edge), crosswise grain (perpendicular to the selvage edge), and bias grain (45-degree angle to the lengthwise or crosswise grain). Each grain behaves differently when fabric is cut or manipulated.
Difference between bilateral and unilateral tolerance?
Unilateral Tolerance :- A tolerancing method using a deviation in only one direction, either plus or minus, from the specified dimension Bilateral Tolerance :- A tolerance method using an equal plus and minus deviation from the specified dimension.

Its very strong, your mums bed is made out of it and it didnt break
What is the weight tolerance for a Franklin Half Dollar What deviation plus or - is allowed by the US Mint from its?
The weight standard in grams is set at 12.50gm. There is no high or low limit for weight deviation, but a total tolerance of 0.259gm. In grains, the weight is set at 192.904 with a total 4.00 grain tolerance. The specifications apply only to Half dollars from 1947 to 1964.
