Rolling Sheet Metal Into A Cylinder Calculator

A mil is equal to one thousandth of an inch.

Rolling sheet metal into a cylinder calculator.

To develop the blank flat length for a cylinder rolled from sheet or plate is quite simple. 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. Last time i did this a customer supplied a blank exactly the length needed to roll the circle. Outside diameter thickness x 3 1416 length of plate required inside diameter thickness x 3 1416 length of plate required.

An example of rolled material would be a rolled carpet or a rolled sheet of paper from the paper mill. Complete roll calculator for the iphone. The material s chemical composition influences yield strength and hardness. 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.

Essentially you should calculate the centerline arc. It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material. This is why such work hardening or self hardening phenomena should be taken into account when evaluating the rolling capacity of a particular machine. 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.

The length units that can be used are yard feet inch meter centimeter millimeter mil and micron. A brief look at a sheet s certificate can tell a fabricator a lot about how the metal will behave in the plate roll. Calculating the developed length of a rolled cylinder. Roll length calculator for smartphones.

Essentially you should calculate the centerline arc. Outside diameter thickness x 3 1416 length of plate required inside diameter thickness x 3. To develop the blank flat length for a cylinder rolled from sheet or plate is quite simple. The urethane will force the material to wrap the upper roll eliminating the end flats.

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.
