How to Calculate Press Brake Stroke Length

A lot of press brake operators get very confused when they’re setting the stroke data (or the Y-axis data) in the press brake controller, especially for the old type press brake. They don’t what exactly press brake stroke they should set, so the only way to solve the problem is test again and again.

Definitely this is not the right way.

Today I gonna show you how to calculate press brake stroke length with exactly formula.

Firstly, please see below schematic diagram. I will take the data on it as example.

And the formula to calculate press brake stroke is:

Stroke = Daylight – Middle Plate Height – Punch Height – Die Base Height – (Die Height – 0.5V + t)

For example:

Daylight: 370mm

Max Stroke: 100mm

Stroke = 370-120-70-75-(26-0.5*8+t) = (83-t) mm

Attention should be paid when choosing the die height:

0.5V＜ Stroke ＜Max Stroke

Easy? Try it out now.
