Abstract [en]

Sandvik Coromant is a leading supplier of tools for the metalworking industry. Sandvik Coromant launches every year thousands of new articles. A number of manufacturing techniques are available for single piece production of tungsten carbide inserts. These methods have their advantages and their disadvantages. Some of these disadvantages might be covered by using milling, however, milling tungsten carbide is hard. An interesting aspect of brittle materials that is researched over the last years is that its properties can be changed locally by applying a large hydrostatic pressure. By doing this, brittle materials like silicon, glass and as well tungsten carbide can be successfully cut. However, this research is based on testing the hypothesis of cutting brittle materials, not on applicability in industry. Due to confidentiality reasons, it is not possible to include more information in this abstract.

Abstract [sv]

Sandvik Coromant är en ledande tillverkare från verktyg för metallbearbetningsindustrin. Sandvik Coromant introducerar varje år tusende nya produkter.Det finns några tillverkningsmetoder för enkelstyckstillverkning av hårdmetall vändskär. Dessa metoder har deras fördelar och nackdelar. Några av dessa nackdelar kan tacklas genom att använda fräsning, men hårdmetall är hårt att fräsa. En intressant aspekt av spröda material som har undersökts under de senaste åren är att egenskaper kan ändras lokalt om ett högt hydrostatiskt tryck tillämpas. Genom att göra så, spröda material som silicium, glas och även hårdmetall kan skäras. Dock bygger forskningen på att testa hypotesen att skära spröda material, inte på dess användbarhet inom industrin. Av sekretesskäl, är det inte möjligt att ta med mer information i denna sammanfattning.
