Product catalog summary

Overview: The document outlines strategies and specifications for machining using various cutter types and inserts, focusing on efficiency and precision in challenging conditions.

Specifications:

Inserts with a diameter of 1.5 mm, 2 teeth, and a radius of 0.2 mm are used. The cutting speed (Vc) is 75 m/min, with a spindle speed (n) of 15,000 rpm, feed per tooth (fz) of 0.05 mm, and feed rate (Vf) of 1,500 mm/min. The depth of cut (ap) is 0.05 mm, and the width of cut (ae) is 0.1 mm, with a machining time of 2.5 minutes.
For larger operations, a cutter with a diameter of 25 mm, 4 teeth, and a radius of 1 mm is used. The Vc is 900 m/min, n is 11,500 rpm, fz is 0.08 mm, and Vf is 4,500 mm/min. The ap is 0.25 mm, and ae is 0.25 mm, with a machining time of 28 minutes.

Procedures:

Four strategies are outlined for handling hardship cases: plunging, z-constant, 5-axis-area-conform, and 45° parallel to axis.
Engraving is also mentioned as a part of the machining process.

Recommendations:

The document suggests using the DUOPLUG® system for high concentricity and rigidity, ensuring vibration-free milling in steep areas up to 90° and deep contours.
It is recommended to use specific cutter types such as milling cutter bodies for round inserts and square shoulder face slotting cutter bodies for optimal results.

Material:

The material used is UDDEHOLM SLEIPNER with a hardness of 58 HRC, noted for good machinability, reduced machining time, excellent ductility, toughness, and high edge stability.
