1. 1. Tribology at the Cutting Edge : A Study of Material Transfer and Damage Mechanisms in Metal Cutting

   Författare :Julia Lundberg Gerth; Urban Wiklund; Uppsala universitet; []
   Nyckelord :Tribology; Metal cutting; Gear hobbing; Wear; Coating; Residual stress; Material transfer; Steel; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

   Sammanfattning : The vision of this thesis is to improve the metal cutting process, with emphasis on the cutting tool, to enable stable and economical industrial production while using expensive tools such as hobs. The aim is to increase the tribological understanding of the mechanisms operating at a cutting edge and of how these can be controlled using different tool parameters. LÄS MER

3. 2. Hardening Distortions of Serial Produced Gears

   Författare :Anders Olofsson; Stefan Jonsson; Julia Gerth; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hardening distortions; crown wheel; main shaft gear; gear runout; back-face tilt; macrosegregation; ingot casting; continuous casting; case hardening; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : Hardening distortions are unwanted changes in shape and dimension that arise during hardening of steel components. Uncontrolled distortions induce random errors to the manufacturing process, and have a strong negative impact on manufacturing costs. LÄS MER
