Toe
Toe turns up in 2 fields: welding, woodworking. Here is what it means to the people in each one.
Toe in welding
The edge of a weld bead, where weld metal blends into the surface of the base metal.
Edge along each side of a weld bead where weld metal meets the surface of the base metal. Toes are the main stress concentration in a welded joint, so undercut, overlap and sharp toe angles there drive fatigue cracking. Fatigue-critical welds are sometimes toe-ground or peened to smooth the transition and extend life.
"Undercut at the top toe is over a thirty-second, dress it with a stringer before you call for inspection."
Toe in woodworking
The longest point of an angled cut on a board or framing member.
The toe is the sharp, leading point of a mitered or beveled cut on a piece of wood. It represents the longest overall dimension of the angled piece, directly opposite the heel, which is the shortest point. Carpenters measure to the toe when cutting trim or rafters to ensure the outside corner of the joint meets perfectly.
"Measure 45 inches to the long point, and mark the toe of the miter right there."
