Can someone tell me how to parameterize a programm?

Sadananda

we are wanting to make the automation as easier as possible for the operator. we have a hydraulic press which we are using for sheet metal bending operation. we want to automate this process with universal robots. And I want to know how to programm a robot parametrically. like when one inputs the sheet metal thichness and bending length it should automatically go and sit in the main programm and main should execute the rest of the defined steps in the programm. I know this is possible, but i am very new to programming UR,s and dont know much of the techniques. I want some knowledgable person to assist.
