  1. 1. Positional Accuracy of Drilled Holes

    Författare :Jacek K Kaminski; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corresponding cutting forces; chip areas; workpiece material; drill wandering; rigidity; drill length; hole-making; surface slope; hole positional accuracy; drilling; conventional point geometry; high-speed steel twist drills; cutting resistance;

    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.
