Sheet Metal Quiz

Here is the Quiz on Sheet Metal for you.

Overview

What is Sheet Metal?

When we work on a thin sheet of thickness 16 gauge to 30 gauge with the help of a simple machine and hand tool, the sheet is termed as sheet metal.

It can be made either from ferrous materials or from non-ferrous materials. These ferrous sheets can be coated or non-coated. Cast Iron, Stainless steel, Carbon steel, Alloy steel, etc have much iron present in them. Hence, it is called ferrous material.

Steel is an alloy of iron and carbon.

Hand Tools used in Sheet Metal

Steel rule

For marking and measuring the linear dimensions. You will get millimeter and centimeter units on one side and in the other side, you will get an inch unit.

The least count of a steel rule is 0.5 mm or (1/64)”.

It is made of hardened steel. After performing heat treatment on high carbon steel or medium carbon steel, we get hardened steel.

Folding rule

it helps in measuring and marking parallel lines and 45-degree angles.

Steel square

It is a marking and measuring instrument. It has two parts. The narrow part is termed as tongue and the wider part is termed the body. It helps to check whether any two adjacent edges are at a right angle or not. Also, it helps to check whether the sheet is square-shaped or not.

Scriber

It is used to draw the marking lines on a sheet or to scratch on the sheet.

There are two types of scribers are available. In one case, the tip of the scriber is straight and for another one, the tip of the scriber is bent at 90 degrees.

Divider

When you require to produce an arc or a circle on the sheet, the divider is used for drawing the arc or circle.

Trammel point

When you can’t use the divider for marking an arc or a circle due to the limitation of space, you should use a trammel point.

Punch

For making any type of operation on a sheet, you need to mark on the sheet as per the requirement of the final job piece. The lines required for marking are drawn by the scriber.

You have to make these lines permanent otherwise the lines will not be visible after some time. For making the markings permanent, you need a punch.

Create permanent dots on the markings with the help of any striking tool and punch. There are two different types of punches.

Prick punch

It produces small dots and the angle between the tips of the punch and the centerline of the punch is 30 degrees to 40 degrees.

Centre punch

It produces the dots at 60 degrees to 90-degree angles.

Various operations performed in Sheet Metal Shop

Scribing or marking operation: marking the lines by scratching on the surface of sheet metal as per requirement, is known as scribing or marking.

Notching: when you need to remove the material from the edge of the sheet as per the desired shape, removing this material is known as Notching.

Slitting: Cutting the sheet of metal in a straight line along the length is known as slitting.

Punching: Creating a cylindrical hole with the help of punch and die in a sheet of metal is termed punching.

Piercing: Creating a hole other than the cylindrical shape with the help of punch and die is termed piercing.

Drawing: For achieving the required shapes, sometimes you may need to stretch the sheet. This stretching operation is termed drawing.

Lancing: Shearing and bending of the sheet are done by striking a lancing tool. This operation is termed Lancing.

Planishing: Making the sheet metal smooth is termed Planishing.

Embossing: When you put an impression of figures or designs on the sheet metal, it is termed embossing.

Forming: When sheet metal is deformed by applying a force to get a required shape is termed forming.

Blanking: This is a metal forming process by which you can remove the material from the primary sheet of metal. The removed material is known as blank.

Perforating: For making a pattern of holes or slots, the sheet metal needs to be fabricated or punched. This is termed Perforating.
