List of Machine Tools used for Cutting Metals! 1. Centre Lathe: The lathe is the father of all machine tools. It is a universal machine tool which can be used—with certain attachment—for many processes. For its development to the form in which we now know it, we owe much to Henry Maudlsey, who developed the sliding carriage, and in 1800 [...]

For many years, the only indices defined to quantify rms variation service quality were the sustained interruption indices (SAIFI, CAIDI, etc.). Sustained interruptions are in fact only one type of rms variation. IEEE Standard 1159-19957 defines a sustained interruption as a reduction in the rms voltage to less than 10 percent of nominal voltage for longer than 1 min. Sustained [...]
In this article we will discuss about the role of coatings on High Speed Steel (HSS) tools. Also learn about the process of deposition of coating on HSS tools in industries. Role of Coatings on HSS Tools: The performance of HSS tools can be enhanced many folds by applying coating of titanium nitride (TiN) on HSS metal cutting tools. This [...]
The following points highlight the seven factors influencing tool life of metals in the industries. The factors are: 1. Cutting Speed 2. Physical Properties of Work Piece 3. Area of Cut 4. Ratio of Feed to Depth of Cut (f/d) 5. Shape and Angles of Tools 6. Effect of Lubricant 7. Nature of Cutting. Factor # 1. Cutting Speed: Cutting [...]
The following points highlight the three main factors responsible for failure of tools in the industries. The factors are: 1. Temperature Failure 2. Rupture of Tool Point 3. Gradual Wear at the Tool Point. Factor # 1. Temperature Failure: During machining at high speeds, very high temperature exists at tool chip interface. When temperature exceeds the critical limit, the tool [...]
In this article we will discuss about:- 1. Definition of Tool Life 2. Ways of judging Tool Life 3. Measurement. Definition of Tool Life: Under the modern methods of machining, it would be desirable to have as long tool life as possible. Tool life has many interpretations, but in general, it is defined "as the actual cutting time between two [...]
