## What is a Data Table – Examples of Data Tables in Engineering

Arranging information into orderly rows and columns is one of the most common forms of communicating precision tabular data. This article explains how tables are used in engineering, how they are created and filled, and includes two real-world examples of their use.

## Determining Lifecycle Replacement Process for Industrial Products

This article shows how product replacement policies and rules are defined, what methods or tools are used to trace and monitor products in their life cycles, and how product replacement is done, or is supposed to be done, according to defined policies.

## Quality Function Development

Quality Function Development techniques achieve tangible quality improvements with sustainable productivity by interpreting customer’s needs and requirements implied in the voice of customer into product specification for achieving cost effective top quality end products and prompt services.

## Horse Power vs Torque – Can Torque to Horsepower be Calculated?

At first glance, torque-power charts seem to show that at a certain engine speed, the two curves cross. Does this really happen? Is it a magic point or just a coincidence? Do the horsepower and torque curves really cross? Can they? Let’s find out.

## Do Engineers Use Differential Equations?

A differential equation is the relation between a function and its derivatives. Many engineering principles can be described based on such a relation. The objective of solving a differential equation is finding the unknown function known as the answer of differential equation.

## Practical Guide for Jig and Fixture Design

This article gives step by step guidelines for a designer on how to systematically go about designing a work holding fixture with hydraulic clamping. Practical advice on what sort of inputs to be collected and how to use common sense in deciding the various design aspects are explained.

## High Speed Steel versus Carbide in Metal Cutting – Why HSS is Still in Use

In understanding metal cutting parameters, the tool material plays a very vital role. High Speed Steel, though used over several decades, is still very much in vogue and it can’t be easily replaced by Carbide in many areas. We have only to see how productively we can continue to use HSS.

## The role of Machinability in metal cutting parameters

The machinability of a material is one of the prime metal cutting parameters that has influence in selecting several other cutting parameters. In this second part of the article series, we shall learn more about machinability.

## Metal Cutting Parameters Basics

Some parameters involved in the metal cutting process are in fact closely related with other parameters; changing one will have an influencing effect on another. This article covers the basic parameters of conventional metal cutting processes.

## Geometric Dimensioning and Tolerancing (GD&T)

GD&T is the symbolic language that enables all proposed users of a design engineer’s work to have the same interpretation of the design drawings.
