With the method we chose to print slabs (figure 8), the cut directions were with-grain (A and B) and cross-grain (C and D), due to the concerns of anisotropic behavior, as discussed in ASTM D412, where the specification indicates, "slabs should be cut so the lengthwise direction of the specimen is parallel to the grain direction
The resulting variations in wood grain (fiber) direction strongly affect the strength of the wood; even a small deviation in grain direction
significantly weakens the lumber.
It was also important that when weld dressing, the system would grind back excessive welds and result in the same finish and the same grain direction
as the welds' surrounding areas.
* Fully integrated support for edge banding with pre-mill allowance, control over top side, and grain direction
Before the finished inlay is pressed and lacquered, checks are made under magnification to ensure that the fit of each piece is perfect and that aesthetically the grain direction
and sand shading are even and consistent.
Young's modulus of PSB can be given using the Hooke's law assuming a uniaxial stress state in the grain direction
Before cutting out a garment, it's important to distinguish when the grain direction
is critical and when it's not.
Parts can be selected from the screen or a kit of parts, and their orientation fixed where grain direction
needs to be maintained, or rotated to any angle.
Use the corner of the blade, and keep the blade parallel to the grain direction
. Next, fill the dent with water and wait until it dries.
As the conductor becomes stretched and relaxed, it can "work harden" and eventually crack along the grain direction
. With such a short perpendicular grain, it may not take much to create this type of crack in the conductor.
The sample is set at the begining with its grain direction
parallel to the trolley movement.
