Manufacturing technologies toward extreme precision
Mechanical machining is further divided into cutting methods, such as turning, milling, drilling, etc, and abrasive machining methods, such as grinding, lapping, and polishing. Additive manufacturing is a process by which a workpiece is constructed by depositing material in layers such that it becomes a predesigned shape.Electrical discharge machining (EDM) can use soft tool electrodes to process hard workpieces to achieve “soft against hard”, because it directly uses electrical energy and thermal energy to remove Parameters Optimization of Electrical Discharge

Aluminum Machining Ardel Engineering and Manufacturing
Aluminum Machining. Machining is a subtractive manufacturing process, meaning it removes material from a workpiece to create the desired part or product. It is highly versatile, accommodating a wide range of metal and non-metal substrates. One of the most common materials used in machining operations is aluminum.Abstract. Chemical machining (CM) is an advanced machining technique that is used to selectively remove material from workpiece using strong chemical reagent known as etchant. The corrosion process is utilised to remove material from the needed area of the workpiece. The material removal in chemical machining process takes place by Chemical Cutting Process SpringerLink

All About Wire EDM Machining: Definition, Application, and
Wire electrical discharge machining (wire EDM) is a process that works by continuously feeding a wire electrode under tension on a vertical axis. Discharge voltage is applied through the wire, crosses via a dielectric liquid, and strikes the grounded workpiece. The workpiece is moved in an X-Y plane to trace a cut pattern through the material.Sivaprakasam et al. [] experimentally studied the possibility of obtaining super surface polish at the nano level, smaller kerf width, and high material removal rate in machining titanium alloy (Ti–6Al–4V) with the Micro-WEDM process.They concluded that when the discharge voltage rises, the value of Ra rises, and then it falls. It has been Performance evaluation of electric discharge machining of

Optimization techniques for energy efficiency in machining
Metal working process is one of the main activities in mechanical manufacturing industry; it is considered as a major consumer of energy and natural resources. In material removal process, the selection of cutting parameters and cooling or cutting liquid is necessary to save energy and achieve energy efficiency as well as It helps to maintain an equilibrium between factors such as costs, product quality, and time. When comparing the 3, 4, and 5-axis machining capabilities, 5-axis CNC machining is not always suitable for all products despite being more effective than 4-axis CNC machining and 3-axis CNC machining. Also, Not all products eligible for 3-axisMulti-Axis Machining: Different Between 3, 4, and 5-Axis CNC Machining

Boring Machining Process: A Detailed Overview WayKen
The primary purpose of boring machining is to broaden or expand the hole in a workpiece. The process cannot create the initial hole; instead, it enlarges the hole at high precision. It is the go-to manufacturing technique for producing holes of specific diameters in a workpiece.It is also a versatile machining process, ideal for machining extremely hard metals and alloys, as well as odd shapes, small sizes, and deep holes. 11.

A systematic review on powder mixed electrical discharge machining
Electrical discharge machining (EDM) is extensively used to machine such a ‘difficult-to-machine’ and high strength and temperature resistant (HSTR) alloys. These materials are generally used in the die and mold making industries [ 3 ]. In 1770, physicist, Joseph Priestly discovered the erosive effect of electrical discharges on metals.Abstract. Nonconventional micromachining processes are developed to meet the manufacturing requirements of new materials and products where usual processes are found inadequate. Based on the type of energy used for material removal, the different micromachining processes are classified into thermal, mechanical, chemical and hybrid Non-conventional Micro-machining Processes SpringerLink
