Progression
The fixed distance a strip advances each stroke in a progressive die; equals the part pitch.
What it means on the floor
The progression (or pitch) is how far the feed moves the strip between strokes. It equals the spacing between identical features from one station to the next and sets how the part is distributed along the coil.
Progression, feed accuracy, and piloting together determine part-to-part registration and material utilization.

Applying the term
Interpret Progression in the context of the drawing, governing standard, and customer requirement in front of you — the same word can carry different limits in design, quality, and production documents. Check whether a stated value is nominal, minimum, maximum, or reference-only, and whether it applies before forming, after forming, or after heat treatment.
