If the material is thin ish like used in sheet metal slip rolls put a piece of urethane sheet under the material as you start into the rolls.
Rolling sheet metal into a cylinder calculator.
Calculating the developed length of a rolled cylinder.
A brief look at a sheet s certificate can tell a fabricator a lot about how the metal will behave in the plate roll.
The k factor of a bend is the ratio of the neutral axis to the thickness so when k 0 50 the neutral axis is in.
It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material.
Last time i did this a customer supplied a blank exactly the length needed to roll the circle.
To develop the blank flat length for a cylinder rolled from sheet or plate is quite simple.
An example of rolled material would be a rolled carpet or a rolled sheet of paper from the paper mill.
Essentially you should calculate the centerline arc.
The length units that can be used are yard feet inch meter centimeter millimeter mil and micron.
How to roll a round cylinder using a hydraulic roller.

Sheet metal cone calculator view the cone instructions below to learn how to manually layout the flat pattern for a truncated cone in single or multiple gore sections.
The perimeter or circumference of a circle is π d where d id the diameter and hence the circumference of your cylinder is π d π 2010 6314 6 mm thus if you take a sheet of metal 6314 6 mm long and roll it into a cylinder the cylinder will have outside diameter of 2010 mm.
