EDM with ultrasonic assistance is a process where ultrasonic vibrations are applied to the workpiece or the electrode during electrical discharge machining (EDM). The ultrasonic vibrations help in improving machining efficiency by reducing tool wear, improving surface finish, and increasing material removal rate. This technique is commonly used for machining hard and brittle materials with high precision.
One type of ultrasonic machining I am familiar with is called "sonic welding". It is used for things like attaching the white plastic button to the metal shaft of a guitar tuner. The button is placed on the shaft, high speed sound waves are directed at the assembly, causing the plastic to melt around the surface of the shaft and secure it there.
Amongst the many types of plastic mold machining, electrical discharge machining is one of the most commonly used. Its main advantages include high precision, precision shape and depth, and a superior surface finish.

Non-traditional machining processes are classified primarily based on the energy source used for material removal. Common categories include mechanical, thermal, chemical, and electrical processes. Mechanical processes involve abrasive or ultrasonic methods, while thermal processes utilize heat to remove material, such as in laser or electron beam machining. Chemical processes encompass techniques like electrochemical machining, and electrical processes include wire EDM and spark erosion.
Computer numerical control (CNC) machining has many benefits over manual machining. To begin, CNC machining is more reliable and accurate because it does not rely on physical labor. With its multi-axis capability, simultaneous operations, and automatic tool changes, it improves production efficiency. CNC machines provide for more freedom of design because they can easily create sophisticated geometries and patterns. CNC machining also facilitates quicker production turnarounds, lowers labor costs, and makes part reproduction less labor intensive. CNC machining has many advantages over traditional machining techniques, including greater accuracy, repeatability, and overall productivity, and the ability to work with a wide variety of materials.
thaper se degree bharoge te yehi haal hoga ....kitabon mein dhoondo internet pe nahi ....hahahahahah
In ordinary machining we use harder tool to work on workpiece , this limitation is overcome by unconventional machining. unconventional machining is directly using some sort of indirect energy for machining. Example : sparks, lasers, heat , chemicals etc.. applied in EDM ,laser cutting machines...etc
Advantages of Non-conventional machining: 1) High accuracy and surface finish 2) no direct contact of tool and workpiece, so there is less/no wear 3) tool life is more 4 ) quieter operation Disadvantages of non-conventional machining: 1) high cost 2) complex set-up 3) skilled operator required
More precise working - machines will always be more precise than human hands. Significantly faster production. Cheaper.
