2. WhatarePunchingMachines? Punching machines are used to structure metals into various desired forms. They are usedtocreatemetalswithdifferentshapesandthicknessaspertherequirement. Hence punching can be referred to as a metal forming process. In this process, the sheetmetalsarepunchedfor creating holes for various purposes. In simpler terms sheet metal punching refers to the process of making holes on metals for various purposes. In order to create effective and efficient holes, many factors have to be taken into consideration like the dimension of sheet metals, the efficiency of the equipment used in the process, the method used for punching, the force applied etc.Various designs can be punched through sheet metals with the help of punching machines.

Manually operatedpunchingmachinesas wellascomputerized punchingmachines. HowareSheetMetalsformed? Sheet metals are formed by pressing metals into very thin, smooth uniform workpieces. Topunch the metal workpieces, the respective machines are tooled with a die and punch to be able to cut and form the metal workpiece. For industrial punching, an extra compression force has to be applied to get the sheet metal into desired form. This processhelps in the initial deformation of sheet metal which is followed by a shear stress that will create fractures and material cutouts. This process begins with the placing of sheet metal in place followed by passing a punch downward through a single side of the sheet metal to get into the die that’s located on the other side of the sheet metal workpiece thereby forming the desired shape. The die also helps in providing the required support for the punch to apply utmost force without the metal being broken. It’s thepunchandthediethathelpsincreatingaccurateandperfectmetalpiecesof

SheetMetalPunchingProcess Todefine what exactly is the process of sheet metal punching, it is when a great shearingforceis applied to remove a material from a sheet metal.In CNC type punching,ithelpstoproducecutoutsandholes of varied shapes and sizes.By punching holes, it means making simple shapes like square, circle, rectangle etc. A combination of these shapes are also possible. It's in the die below the sheet that holds thedesiredshapetobecut.Eventhoughdiesandpunchesof standard size and shapes are used, custom made sizes and shapes can also be created for punching complex requirements. It’s the punch press that helps to drivedown at great speed all the way through the sheet and to the die. What causes the workpiece to swiftly bend, and fracture is the tiny clearance gap that’s seen in between punch edge and die. The punched out slug makes a free fall through the opening of the die that is tapered.Even though these processes can be done on manual punch presses, CNC presses are mostly made use of nowadays.

But with the advent of technology, automated punching machines made their way through. The automation of punching machines contributed a lot to the speed and the accuracy of punching of even intricate shapes. Manual punching machines are still on use for specific job but very limited.
