After replacing the cutter head in a polyolefin pelletizer, how can one determine the relationship between rotational speed and feed pressure? I hope the experts can give some advice~

As asked in the title, what are the methods to determine the relationship between the cutting tool speed and the forward pressure?
It’s hard to correspond to this question, right? The rotation speed is generally adjusted in response to changes in load, particle shape, and the melt index of the product ； Automatic feed is carried out based on tool pressure, tool wear, and changes in particle shape; the tool pressure must not be too high nor too low.
There must be a corresponding relationship; I’ve seen a table showing the relationship between production volume and rotation speed. It’s simple – just adjust the thickness of the particles. I’ve seen the table showing the relationship between rotation speed and cutting force, but I don’t know how it was derived
Could you find this table for me? I really want to learn it!* Thank you
It should be based on force balance; by analyzing the forces acting on the cutting tool, the forces on both sides are balanced
It seems to be based on the wind pressure curve; there must be some adjustment after sharpening, determined by the granulation effect!
