Punching is a forming process that uses a punch press to force a tool, called a punch, through the workpiece to create a hole via shearing. Punching is applicable to a wide variety of materials that come in sheet form, including sheet metal , paper , vulcanized fibre and some forms of plastic sheet.
The selection criteria of all process parameters are governed by the sheet thickness and by the strength of the work-piece material being pierced.
