Approaches for Preventing Tool Wear in Sheet Metal Forming Processes

Sheet metal forming processes, the purpose of which is to give shaped material appropriate mechanical, dimensional and shape properties, are characterised by different values unit pressures lubrication conditions. Increasing efficiency tool work increasing their durability, reliability still one main indicators production efficiency. Tool wear in technologies significantly differs from character other methods metalworking, such as machining. This article presents characteristics mechanisms used sheet forming. Possibilities durability tools applying coatings produced laser techniques, chemical vapour deposition also discussed. Great emphasis placed on self-lubricating functional materials coatings. Current trends lubricants forming, including texturing, presented.
