Machining processes ECM Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods.[1] Its use is limited to electrically conductive materials. ECM can cut small or odd-shaped angles‚ intricate contours or cavities in hardened exotic metals‚ such as titanium aluminised‚ Inconel‚ Waspalloy‚ and high nickel

Machining Operations In MACHINING‚ the shape‚ size‚ finish and accuracy are obtained by removing the excess material from the workpiece surface. Various surfaces are obtained as an interaction between a workpiece and a cutting tool with the help of a contrivance known as MACHINE TOOL. Prof. S.K. Choudhury‚ Mechanical Engineering Department‚ IIT Kanpur 1 Advantages and Disadvantages of Machining Variety of work materials can be machined. o Most frequently used to cut metals Variety of

ABRASIVE JET MACHINING INTRODUCTION:- IT IS A PROCESS OF MATERIAL REMOVAL THROUGH THE ACTION OF A FOCUSED STREAM OF FLUID WITH ABRASIVE PARTICLES. IT IS ESPECIALLY USED FOR MACHINING SUPER ALLOYS‚ CERAMICS; GLASS AND REFRACTORY MATERIAL. IT IS ONE OF THE NON-POLLUTING METHODS AVAILABLE FOR MACHINING HARD MATERIALS TO PRECISION DETAILS. IN ABRASIVE WATER JET MACHINING THE ABRASIVE PARTICLES UTILIZES WATER JETS TO ACCELERATE OR DECELERATE THEIR SPEEDS DEPENDING UPON THE TYPE OF MATERIAL TO BE MACHINED

lConventional Machining VS Non-Conventional Machining Conventional machining usually involves changing the shape of a workpiece using an implement made of a harder material. Using conventional methods to machine hard metals and alloys means increased demand of time and energy and therefore increases in costs; in some cases conventional machining may not be feasible. Conventional machining also costs in terms of tool wear and in loss of quality in the product owing to induced residual stresses during

NONTRADITIONAL MACHINING AND THERMAL CUTTING PROCESSES Review Questions 26.1 Why are the nontraditional material removal processes important? Answer. Reasons for importance of are nontraditional material removal processes (1) the need to shape new metal alloys and non-metals that are difficult to machine by conventional processes; (2) the requirement of unusual and complex workpart geometries; and (3) the need to avoid surface damage which is often associated with conventional machining. 26.2 There
