8. Positional Accuracy of Drilled Holes
Sammanfattning : When selecting hole-making sequences, the positional accuracy mainly is determined during the first drilling operation. This dissertation consists of three papers which consider the influence of various factors on hole positional accuracy when drilling in inclined workpieces using high-speed steel twist drills with conventional point geometry.

9. 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
