Conventional Metal Cutting - Understanding the Roles Played by Various Cutting Parameters - (b) Tool Material - HSS

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...

Conventional Metal Cutting - Understanding the Roles Played by Various Cutting Parameters - (a) Machinability

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.

Conventional Metal Cutting – Understanding the Roles Played by Various Cutting Parameters

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.

Lifecycle Product Replacement Process

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...

The Point Where Horsepower and Torque Curves Cross

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...

Differential Equations In Engineering

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...
