Various Sheet Metal Cutting Operations

It is a cutting operation by which various shaped holes are made in sheet metal.

Various sheet metal cutting operations.

Punching is similar to blanking except that in punching the hole is the desired product. In which enough scrap is left all around as shown in fig. 22 different types of lathe machine operations. Sheet metal cutting operations involve the removal of the material from larger sheets.

Sheet metal cutting operations. Many sheet metal cutting operations are based on computer numerically controlled cnc laser cutting or multi tool cnc punch press. The material punched out from the hole being waste. Press working operations or sheet metal operations.

Shearing is the process of separating the sheet metal into two or more pieces normally by cutting along a line. The first one is sheet metal cutting second one is sheet metal bending or forming and the last one is known as deep drawing in this article we mainly focus on sheet metal cutting operations and other two we will discuss into upcoming articles. Simply put cutting operations cause the sheet metal to be stressed beyond its ultimate strength therefore breaking its structure and separating into different parts. It is an operation of cutting a whole piece from sheet metal.

Blanking is a cutting process in which a piece of sheet metal is removed from a larger piece of stock by applying a great enough shearing force in this process the piece removed called the blank is not scrap but rather the desired part blanking can be used to cutout parts in almost any 2d shape but is most commonly used to cut workpieces with simple geometries that will be further shaped. Variety of sheetmetal cutting operations are possible. Sheet metal can be cut in various ways from hand tools called tin snips up to very large powered shears. With the advances in technology sheet metal cutting has turned to computers for precise cutting.

In this article we will discuss various sheet metal cutting operations and their application. A punch and die is applied for this type of sheet metal operation. Sheet metal cutting occurs due to shearing forces acting on the metal through the edges of the punch and die. Industrial sheet metal cutting operations such as this will usually incline the punch so as to reduce the maximum force needed by distributing the required force over the cutting stroke.

By physical removal of the material from the sheet if the required shape of the component is obtained called as cutting or shearing. It is the cutting operation with the help of which holes of various shapes are produced in the sheet metal it is similar to blanking only the main difference is that the hole is the required product and the material punched out from the hole is considered as a waste.
