I have some difficulties on calculating the reduction on cold rolling process but mi signs is negative. Is that normal? Cheers

Cold rolling reduction is a process in which a metal strip or sheet is compressed between two rollers to reduce its thickness and increase its strength and surface finish. It is commonly used in the manufacturing of steel and aluminum products.
Cold rolling reduction is calculated by subtracting the final thickness of the metal strip or sheet from its initial thickness, and then dividing that value by the initial thickness. The result is then multiplied by 100 to get the percentage reduction.
Negative signs in cold rolling reduction calculations can be caused by a variety of factors, including incorrect measurements, errors in the calculation formula, or issues with the machinery used in the rolling process.
To troubleshoot negative signs in cold rolling reduction calculations, it is important to double check the measurements and calculation formula used. If these are correct, then the issue may lie with the machinery and it may be necessary to check for any malfunctions or adjustments needed.
Yes, negative signs in cold rolling reduction calculations can be corrected by identifying and addressing the underlying issue. This may involve recalculating the reduction using correct measurements and formula, or making adjustments to the machinery to ensure accurate results.
