Boring: Calculating deflection

Eliminating chatter, especially when boring deep holes, is one of the greatest machining challenges.

Understanding the Identification System for Indexable Inserts

American National Standard ANSI B212.4-2002 covers the identification system for indexable-type inserts for both single-point and multiple-point cutting tools. It was published on October 29, 2002.

Calculated forces when turning

The cutting force when turning is a resultant force that combines tangential, feed and radial force components. These force components can be measured with a three-component force dynamometer. Metalcutting professionals consider Kistler dynamometers the most accurate.

Understanding tangential cutting force when milling

The tangential cutting force and the cutting speed allow you to calculate the required machining power for an operation.

Cutting Time for Facing

Comparison between calculating cutting time when facing at a constant cutting speed vs. a constant rpm.

New mill

A new concept of calculating the required machining power when milling.

Tool steels' dual personality

The guidelines for turning of tool steels include both tool- and part-making applications.

Tackling Titanium

Maximizing productivity and calculating required machining power when facemilling titanium alloys.

Tools With Abrasive Personalities

Machining polymetric composite materials with single-layer diamond abrasive tools.

Face Off

Keys to maximizing productivity when facemilling steel.

Cast Contents

Choosing the right cast aluminum and aluminum alloys from among the hundreds of different grades and the many tempers in each grade requires understanding of the materials' designation system to know their compositions, tempers and properties.

Hard Tools for a Fine Finish

Superhard finishing tools may benefit machined parts via finer surface finishes, greater wear resistance and harder, stronger microstructures. Also, some of the tools can last longer than their conventional counterparts.

Composition Matters

Knowing the aluminum alloy grades allows shops to maximize productivity.
