2. 1. Cryogenic Machining of Ti-6Al-4V

   Author : Simon Isakson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cryogenic machining; Titanium; Surface integrity; Wear; Residual stress;

   Abstract : The use of cryogenic coolants such as liquid nitrogen or liquid carbon dioxide has emerged as a sustainable alternative to conventional cutting fluids during machining operations, with the potential to increase tool life, leading to productivity gains, as well as to improve the surface integrity of the machined components. In addition, the machined surfaces are left residue-free after the process and there are no used cutting fluids to dispose of. READ MORE

4. 2. On the Machinability of Ductile and Strain Hardening Materials - Models and Methods for Analyzing Machinability

   Author : Fredrik Schultheiss; Industriell Produktion; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Ti6Al4V; Duplex stainless steel; Machinability; Minimum chip thickness; Contact condition; Surface topography; Tool wear; Part cost; Sustainable machining; Polar diagram.;

   Abstract : As quality and performance demands on today’s products increases, more and more advanced materials are being used during modern production. The problem is however that this in turn place new demands on the machining processes utilized. READ MORE

5. 3. The effect of workpiece material and its microstructure on tool wear in metal cutting

   Author : Philipp Hoier; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scanning electron microscopy; Superalloy; Cutting tool; Wear; Cemented carbide; Steel; Machining;

   Abstract : The aim of the present work is to promote the basic understanding of how the workpiece material and its microstructure affect the tool wear during metal cutting. To isolate the effect of the workpiece material, the tool material (uncoated cemented carbide) was kept constant while the workpiece was varied. READ MORE

6. 4. A study of process planning for metal cutting

   Author : Staffan Anderberg; Lars Pejryd; Tomas Beno; Mats Andersson; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; CAPP; CAM; efficiency; performance; green manufacturing; sustainable machining; CNC; Produktionsberedning; effektivitet; grön tillverkning; Industrial engineering and economy; Industriell teknik och ekonomi; Manufacturing engineering; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : Process planning as a function for competitiveness is often neglected. However, as an intermediary between product development and manufacturing, it holds a key function in transforming product specifications and requirements into a producible process plan. READ MORE
