1. Machining of Some Difficult-to-Cut Materials with Rotary Cutting Tools
Sammanfattning : Automobile and aero industries have an increasing interestin materials with improved mechanical properties. However, manyof these new materials are classified as difficult-to-cut withconventional tools. It is obvious that tools, cutting processesand cutting models has to be devel-oped parallel to materialsscience. LÄS MER
2. Influence of Microstructure in Machining of Nickel and Nickel-Iron Based Alloys
Sammanfattning : Superalloys are used in applications such as turbines, steam power plants and nuclear power systems in components that require good high temperature properties and/or corrosion resistance. They are classified as difficult-to-cut materials and hence, from a sustainable production point of view, tool wear and tool life are major factors when machining these alloys. LÄS MER
3. Advances in High Porductivity - High Quality Machining
Sammanfattning : Quality, productivity and flexibility are vital factors in todays machining industry in order to remain competitive. Nowadays, finished products not only have to be produced within specific tolerance limits, but they also have to posses high standards in terms of surface integrity, i.e. LÄS MER
4. Finnskägg, tåtel och sia : Om folkliga namn på gräs
Sammanfattning : By collecting and analysing plant names linguistically, a knowledge of popular botany and its relationshipto scientific botany can be obtained.This study has two primary aims: to describe the popular botanical view of the part of thevegetal world represented by grasses and to illustrate the dialectal use of plant names.

5. Characterization of WC-Co tools used for machining of Alloy 718 under the influence of high-pressure coolant supply
Sammanfattning : The use of high-pressure jets for supply of coolant to the cutting zone has the potential to significantly increase the productivity and process stability when machining difficult-to-cut materials such as Ni-based superalloys. Apart from better chip-breakability, the jets enable the coolant to reach closer to the cutting edge and hence enhance its capability to dissipate heat. LÄS MER
