Sneck, frame straightening is getting your bike back into shape after, say, you have dropped it, or it has been involved in a crash.

The most common frame straightening is a simple check that the geometry of the machine is correct.
Some machines deviate from a straight line when the handle-bars are unattended.
The alignment of both wheels are checked.
The alignment and angle of the steering head to the swing-arm axis is another most important check.
The alignment of the drive sprocket to the above is also important.
The last one is the alignment of the swing-arm axis to the rear axle.

The above alignments are all checked and pressed and pulled into shape by the frame straightener using fundermetal jigs. On a massive end-over-end prang the frame straightener has to also ascertain if indeed the engine aligns with the mountings. Usually a frame straightener is consulted if the handling feels strange or you have purchased a frame of an unknow history and want to restore it.
