  2. 1. Methods and Models for Cutting Data Optimization

    Author : Sören Hägglund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool Life; Cutting Forces; Tool Replacement Coordination; Process Cost; Tooling Cost; Cutting Data Optimization; Surface Finish; Cycle Time Balancing;

    Abstract : Traditional optimization of cutting processes refers to minimizing cost or minimizing time (minimumcost or maximum production rate). These criteria apply to the cutting speed via well-known equationsfor economic tool life and tool life for maximum production rate. Quite often speed is focused firstwhen after some suitable feed value is chosen. READ MORE

  4. 2. Positional Accuracy of Drilled Holes

    Author : Jacek K Kaminski; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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.
