Unit 4: Micro Machining and Nano Fabrication Techniques 1. Since laser machining is a thermal process, heat-affected damage does occur and can have a negative impact on the end use, especially in high-reliability applications. These cracks can be closed by applying a proper adhesive which is used for bonding the inlet/outlet ports. Micro machining processes (MMPs) are used to increase selectivity, accuracy, performance, etc. Abstract : Electrical Discharge Machining (EDM) is a non-traditional machining process used for machining of hard materials. Ultrasonics, vibrations of frequencies greater than the upper limit of the audible range for humans—that is, greater than about 20 kilohertz. Complex and concave curvature parts can be produced easily by the use of convex and concave tools. One such process is chemical–mechanical polishing, which removes the material by the combined action of chemical process and stresses caused by polishing.

Parametric optimization of PTFE using Ultrasonic Machining - A review 1Pavan Ghelani,2Ujawala Salunkhe 1PG Student,2Asst. Ultrasonic machining employs the high-intensity vibrations of a transducer to move a machine tool. –Can be used to machine various conductive materials –Gives good surface finish –Machining of very thin section is possible –Does not leaves any chips or burrs on the work piece –High accuracy is obtained –Fine holes can be easily drilled –Process once started does not need constant operators attention –It is a quicker process Technological improvement of machining processes can be achieved by combining different machining actions or phases to be used on the material being removed. ApplicationsIt is mainly used for(1) drilling(2) grinding,(3) Profiling(4) coining(5) piercing of dies(6) welding operations on all materials which can be treated suitably by abrasives. • The tool, which is a negative of the work piece, is vibrated at around 20KHz with and amplitude of between 0.013mm and 0.1mm in abrasive slurry at the work piece surface. Prof. 1 Department of Mechanical Engineering, 1Babaria Institute of Technology, Vadodara,India _____ Abstract - The objective Of Study to develop an ‘Experimental Set-up’ of the process that can be used for a better Ultrasonic machining is of particular interest for the cutting of non-conductive, brittle workpiece materials such as engineering ceramics. Electric discharge machining, also known as spark erosion, electro-erosion or spark machining is a process of metal removal based on the principle of erosion of metals by an interrupted electric spark discharge between the electrode tool cathode and the work anode. The major disadvantages of this process are that only electrically conducting materials can be machined. Machining. This is the complete explanation on Machining Process. It is used for machining steam turbine blades within closed limits. -The laser used can be of solid or gaseous type -It is a thermal cutting type process -The light radiated from flash lamp is directly focused on workpiece -Any material can be machined irrespective of its physical and mechanical properties. The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing. The machining can be performed on a lathe machine, milling machine, ultrasonic machining, etc. Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. Chemical and electrochemical machining processes provide very good surface finish by making use of principles of chemistry. The EDM process can be used on any materials that are an electrical conductor. Hence, USM is mainly used for machining brittle materials which are poor conductors of electricity and thus cannot be processed by Electrochemical and Electro-discharge machining (ECM and ED). “Rotary Ultrasonic Machining is the process in which, interrupted drilling of small-diameter holes takes place.” a) True b) False View Answer The large stock might be in any shape such as solid bar, flat sheet, beam or even hollow tubes. (8) Used for machining round, square, irregular shaped holes and surface impressions. We have also a Facebook community for you guys. The ECM process is used for die sinking operation, profiling and contouring, drilling, grinding, trepanning and micro machining. A variation of this technique is ultrasonic drilling, which makes use of pneumatic vibrations at ultrasonic… Learn vocabulary, terms, and more with flashcards, games, and other study tools. High accuracy of about 0.005 mm can be achieved. CO2 Summarize the principle and processes of abrasive jet machining. (7) Used for machining hard and brittle metallic alloys, semiconductors, glass, ceramics, carbides etc. -Ultrasonic Machining -Electrochemical Machining -Abrasive Jet Machining -Laser Beam Machining Which of the following is not true for Laser beam machining? Abrasive slurry is interposed between tool and work piece and the tool is used as a micro-mill to obtain drills or pattern on the work piece surface. 1.PROCESS PRINCIPLES •Ultrasonic Machining (USM) is a mechanical material removal process used to erode holes and cavities in hard or brittle workpieces by using shaped tools, high frequency mechanical motion, and an abrasive slurry. Machining is manufacturing process that involves removing materials using cutting tools for getting rid of the unwanted materials from some workpiece and converting it into the shape you desire. Ultrasonic machining is able to effectively machine all materials harder than 40HRC, whether or not the material is an electrical conductor or an insulator. Electrical discharge machining (EDM) is a non-traditional machining process based on removing material from a part by means of a series of repeated electrical discharges between tools, called electrodes, and the part being machined in the presence of a dielectric fluid. 1954 –Manufacture or USM machine tools. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams. The term sonic is applied to ultrasound waves of very high amplitudes. Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. EDM processes are used for cavity machining, producing dies and molds, and intricate machining operations in hard, difficult to machine. 1951 –First report on equipment and technology of USM. 5. Good surface finish can … Development of USM was promoted by increasing use of hard and brittle materials. Hypersound, sometimes called praetersound or microsound, is sound waves of frequencies Combination of two or more processes is also in vogue. Wang, 1997). ECM can be used for copying of internal and external surfaces, cutting of curvilinear slots, machining of intricate patterns, production of long curved profiles, machining of gears and chain sprockets, production of integrally bladed nozzle for use in diesel locomotives, production of ECM can be used for slotting very thin walled collets 3. In contrast, ultrasonic machining (UM or USM) is a non-thermal, non-chemical and non-electrical machining process that leaves the chemical composition, material microstructure and physical properties of the workpiece unchanged. The advancement of machining can be performed on CNC Machines where there is no intervention of humans. 2. •USM is able to effectively machine all materials harder than HRc40, whether or not material is an electrical conductor or an insulator. (It should be noted that Langenhorst did point out that you can use wire EDM to cut shims by stacking the stock, sandwiching it between two pieces of quarter-inch steel, and cutting off a … State whether the following statement is true or false. Here are some advantages of Electro discharge machining: It can be used for any hard material and even in the heat-treated condition. Advantages of Electro Discharge Machining. Negligible tool wear.
