Concept for Software Program Development

It sounds like you might need to look from another "angle" at your challenge.

What you need to know is the distance of each punch relative to the cut-off shear AND the distances you want the holes or deformations to be from the end of the produced unit.

This will then enable you to determine the action sequence for the punches and shear as your stock progresses through the device. With single direction feed, you only get one opportunity to punch the stock at the right places as it passes along and those places are relative to the shear.

You might also need to consider your parts to be coming through "end first" rather than "front first".

Good luck.

Yes, I know the actual distances between each punch & shear too.

My concern is, how do i calculate ( i mean mathematical formula) feeding positions for servo drive & after completing the feeding how shall i decide to operate that only required punch station to make hole.

Generally you have a software program that runs the machine and you just punch in values for the piece you want to produce...you have to know the type of machine it is and its capabilities...

You need to locate the manual and setup guide that comes with the machine, and it's best to have someone familiar with how the machine works to show you how it works for how ever many times as it takes you to learn...
