CHAPTER 1
INTRODUCTION
The machining conductive as well as nonconductive advanced engineering materials such as glass, ceramics, quartz, granite and composite materials are difficult to machine by usual process. These materials are having wide range of applications in the field of automobile, aerospace and defense field. So processing of these materials is necessary with easy and economical way. Hence Hybrid Machining Process (HMP’s) like ECSM is evolved and is shown in fig1.1. ECSM is the combination of ECM and ESM process, Electro Chemical Machining (ECM) and Electro Spark Machining (ESM) can machine only electrically conductive materials and these two are mot preferable for machining non-conducting and partially conducting advanced materials. …show more content…
In this project combination of sodium hydroxide and potassium hydroxide is used as electrolytic solution.
1. Caustic soda (NaOH)
It is also known as sodium hydroxide, having caustic metallic base. It is hygroscopic readily absorb water as presented in air, so it should be stored in a container. Caustic soda is soluble in water with the liberation of heat along with also dissolves in ethanol and methanol, although it shows lower solubility in these solvents than potassium hydroxide. Molten sodium hydroxide is also a strong base, however high temperature is required to limits applications. Sodium hydroxide solution will leave a yellow stain on fabric in addition to paper.
It is used in several industries, mostly as a strong chemical base in the produce of pulp and paper, textile, drinking water, soaps plus detergents in addition to a drain cleaner. Unpolluted sodium hydroxide is a white solid obtainable in the form of pallets; flake granules furthermore as a 50% saturated solution.

Caustic potash is usually in the form of pallets, it will tracks in air because KOH is also hygroscopic. As a result, KOH is typically contains varying amount of water as well as carbonates. When it dissolved in water is sturdily exothermic, meaning the process gives momentous heat. Even at elevated temperatures, rock-solid KOH does not dehydrate readily. Thermal stability: NaOH and KOH exhibits elevated thermal stability. Because of its high stability along with relatively low melting point, this is often melt cast like pellets or rods, form with the purpose of have low surface area and convenient handling properties. As a base, KOH is highly basic, creating strong alkaline solutions in water and other solvents. In analytical chemistry, titrations using solutions of KOH are used as test acids.

Micromachining

...At this time, unfortunately, a convergence in terminology has not been forthcoming and, hence, a definition of the term Micro-Machining to be implied in the context of this assessment is in order. In principle, one may take two viewpoints:(1) The first viewpoint may define Micro-Machining as the collection of all cutting operations that are performed on micro/meso-scale components and products that fall into the 100 μm to 10,000 μm size range as shown in the figure below. The Micro-Machining regime is characterized by the requirement of producing high accuracy complex geometric features in a wide variety of materials in the above-defined size range. These requirements impose the use of considerably downsized tooling (micro-tools, e.g. endmills in the 50 to 500 micron diameter range), small undeformed chip thicknesses and feedrates (submicron to a few microns) and speed settings (50K to 200K RPM might not be uncommon) that would be considered technologically infeasible at the conventional macro-scale. As a consequence, the principal distinction between Macro and Micro-Machining operations emerges and manifests itself as the dominance of ploughing and rubbing phenomena at the cutting edge over shearing and the necessity to take micro-structural effects into consideration. (2) The second viewpoint approaches the definition of the Micro-Machining regime from the standpoint of the magnitude of the undeformed chip thickness being removed in the cutting process. It is difficult to define...

...ch05.qxd 9/27/04 4:19 PM Page 174  CHAPTER Q1 Q2 Q3 Q4 Q5 Q6 Job Costing In Brief Custom products and services, which are produced singly or in small batches, need to be valued for financial statements, tax reporting, and management monitoring. Job costing is an accounting method used to assign product costs to custom products or services. In job costing, direct costs are traced and overhead costs are allocated to individual jobs. Sometimes defects occur in custom products. Defective units can sometimes be reworked. The costs for both spoilage and rework need to be accounted for, as does the cost of scrap that arises from production. This Chapter Addresses the Following Questions: How are costs assigned to customized goods and services? How is overhead allocated to individual jobs? What is the difference between actual costing and normal costing? What are the uses and limitations of job cost information? How are spoilage, rework, and scrap handled in job costing? What are the quality and behavioral implications of spoilage? ch05.qxd 9/27/04 4:19 PM Page 175 BOMBARDIER: CUSTOM MANUFACTURING n 1942, the Canadian company L’AutoNeige Bombardier Limitée began manufacturing tracked vehicles for snow-covered terrain.

Additive Mnaufacturing

...Front. Mech. Eng. 2013, 8(3): 215–243 DOI 10.1007/s11465-013-0248-8 REVIEW ARTICLE Nannan GUO, Ming C. LEU Additive manufacturing: technology, applications and research needs © Higher Education Press and Springer-Verlag Berlin Heidelberg 2013 Abstract Additive manufacturing (AM) technology has been researched and developed for more than 20 years. Rather than removing materials, AM processes make three-dimensional parts directly from CAD models by adding materials layer by layer, offering the beneficial ability to build parts with geometric and material complexities that could not be produced by subtractive manufacturing processes. Through intensive research over the past two decades, significant progress has been made in the development and commercialization of new and innovative AM processes, as well as numerous practical applications in aerospace, automotive, biomedical, energy and other fields. This paper reviews the main processes, materials and applications of the current AM technology and presents future research needs for this technology. Keywords additive manufacturing (AM), AM processes, AM materials, AM applications 1 Introduction The ASTM F42 Technical Committee defines additive manufacturing (AM) as the “process of joining materials to make objects from three-dimensional (3D) model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies” [1]. It is also known as additive fabrication, additive processes, direct digital...

...Supplier Development at Honda, Nissan and Toyota: Comparative Case Studies of Organizational Capability Enhancement* Mari Sako Professor of Management Studies Said Business School University of Oxford Park End Street Oxford OX1 1HP, UK Email mari.sako@sbs.ox.ac.uk October 2002 * This study was funded by the International Motor Vehicle Program (IMVP), the UK Economic and Social Research Council, and the Japan Foundation. I am grateful to the interviewees at the three automakers and suppliers who gave generously of their time. I also appreciate the comments of many colleagues, and in particular those of Bill Lazonick. Abstract What factors facilitate and constrain the development and replication of organizational capabilities at suppliers? This question is addressed in a comparison of historical case studies at Toyota, Nissan and Honda in Japan. First, as expected, replication difficulty is overcome by enabling companies to share the process of accumulating tacit knowledge. Second, the interdependence in the hierarchy of routines, that constitute organizational capabilities, has led companies to broaden the scope of supplier development. Third, this broadening challenges suppliers to accept buyer companies’ intervention in internal investment decisions, requiring a certain type of corporate governance. It is argued that the boundary of a capability-based organization may go beyond legally distinct units of financial control when firms are subjected to a cumulative process...
