In the fifth installment of Metric Matters, Dr. Edumnd Isakov returns to 1948 and the ninth meeting of the General Conference on Weights and Measures.

In the fourth installment of Metric Matters, Dr. Edumnd Isakov delves into SI-derived units of measurement.

In the third installment of Metric Matters, Dr. Edumnd Isakov delves into the measurement of electric currents.

Originally called a grave, meaning heavy, learn more about the history of the kilogram.

The first in a series of articles about the metric system from Dr. Edmund Isakov.

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

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.

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.

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

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

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

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

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

Keys to maximizing productivity when facemilling steel.

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.

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.

Knowing the aluminum alloy grades allows shops to maximize productivity.

Data on alloy steels and tool material grades to maximize turning efficiency. Guidelines for turning alloy steels.
