Abstract
We've already developed “Serial Multi-Point Method” to measure the surface profile with high accuracy.
In the method mentioned above, measuring point interval must be as same as the sensors' span and can't be shorten at will.
So, after confining the area of application only to roll used for plate rolling, we'll propose a supplemental method to shorten the measuring point interval arbitrarily.
In this method, we assume several groups of measuring points, points belonging to same group are of same interval as the sensors' span, and groups are slightly shifted one another to the measuring line-ward to place each one point of every group in a row by rotation.
And, the lower-powered function is utilized to acquire the macro shape common to all the groups' profiles measured beforehand with “Serial Multi-Point Method”
Then using this macro shape as the guide, each of profiles is moved and unified to obtain the final result of short measuring point interval.
We also certify the feasibility of this method with carrying out the numerical simulation, and with giving the proof of existence of the solutions namely coefficients of lower-powered function and quantities of move to be added to unify individual profiles into one.
