1. Adhesive wear testing and modelling of tool steels sliding against sheet metals
Sammanfattning : Sheet metal forming is a manufacturing method used because of its versatility. Sheets are plastically deformed by a tool to create a product. A tool is expected to last for several 100,000 forming operations and efforts are made to optimize the tools. A common type of wear referred to as galling is the adhesion of sheet material to the tools. LÄS MER
2. On tool steel, surface preparation, contact geometry and wear in sheet metal forming
Sammanfattning : In sheet metal forming operations the life length of the production equipment islargely dependent on the wear of the tools that are in direct contact with the sheet.One form of adhesive wear where some sheet material gets transferred to the tool, alsoknown as galling, is the most common cause of tool failure.
