The following article will guide you about how to design a gating system used in casting of metal. Design of Gating System: The design of a gating system depends on both the metal and mould compositions. For example- an elaborate gating design is needed to avoid dross (e.g., oxides) in easily oxidized metals of low melting point such as aluminium. [...]
Material Properties: Alloying, Heat Treatment, Mechanical Working and Recrystallization! Method # 1. Alloying: Alloy steels are broadly classified into two categories: (i) Low Alloy Steels (ii) High Alloy Steels In low alloy steels, the total content of the alloying elements, such as Cr, Ni, Mo, V, and Mn, is kept within 5%. Each alloying element imparts a specific property to [...]
In this article we will discuss about the unconventional machining processes:- 1. Abrasive Jet Machining (AJM) 2. Electron Beam Machining (EBM) 3. Laser Beam Machining (LBM) and 4. Plasma Arc Machining (PAM). And also learn about:- Unconventional Machining Process, Characteristics of Unconventional Machining Process and Classifications of Unconventional Machining Processes. Abrasive Jet Machining (AJM): In AJM, the material removal takes [...]
The following points highlight the four main steps involved in the casting process. The steps are:- 1. Preparation of Pattern and Mould 2. Melting and Pouring of the Liquefied Metal 3. Cooling and Solidification of Liquid Metal 4. Defects and Its Inspection. Steps involved in the Casting Process # 1. Preparation of Pattern and Mould: A pattern is the replica [...]

This article throws light upon the types of machining process. The types are:- 1. Shaping and Planning 2. Turning and Boring 3. Drilling and 4. Milling. It is necessary to have some exposure to the actual machining operations and their analyses. In this article, we shall not go into the extreme technological details and all possible types of operations, but [...]
In this article, it will be attempted to present a quick overview of the different generative processes. Since this area is growing and many processes are still not fully matured, only brief descriptions can be presented. However, the process stereo lithography was the first GMP to be developed and commercialized by 3D Systems Inc. and will be discussed in more [...]
We have given a brief description and analysis of each of the various basic forming operations. It is hoped that the reader has by now acquired some idea about these processes, especially about the mechanics involved. However, there are many minor and major variations of such processes. In this article, we shall discuss some of these along with the associated [...]
