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.
Additive processes involve adding material to the piece. Subtractive processes involve taking material from the piece. Painting is additive because you add paint. Carving is subtractive because you take away pieces from your original block.
The tool post in machining provides several advantages, including precise positioning of cutting tools for accurate measurement and consistency in machining operations. It allows for quick and easy tool changes, enhancing productivity and reducing downtime. Additionally, a well-designed tool post can improve stability and rigidity, leading to better surface finishes and extended tool life. Overall, it enhances the efficiency and effectiveness of machining processes.
Machined surface is more rough.
The adaptive control is basically a feedback system that treats CNC as an internal unit in which the machining variables automatically adapt themselves to the actual conditions of the machining process.
we use water for maching in WJM, and abrasives in AJM.
Machining process is a broad term that refers to the cutting processes, abrasive processes and the non-traditional machining processes.
General machining processes include turning, shaping, milling, drilling, sawing, abrasive machining, and broaching.
The need for non-conventional machining begins with the need for alternative energy sources. Non-conventional machining requires the use of alternative energy sources including thermal energy or solar energy.

Roofing is a nontraditional occupation for women. Men have entered the nontraditional occupation of nursing.
Neither the tool or the workpiece rotate
Some good metals for machining include aluminum, brass, copper, stainless steel, and titanium. These metals are known for their machinability and can be shaped and formed accurately with various machining processes.
Machining is distinguished from other manufacturing processes by its method of material removal, where excess material is precisely cut away from a solid workpiece to achieve desired shapes and dimensions. Unlike processes such as casting or molding, which involve shaping materials through forming, machining typically involves tools like lathes, mills, and drills. This high precision and ability to produce tight tolerances make machining ideal for creating intricate components in industries such as aerospace and automotive. Additionally, machining often requires less tooling and can be more adaptable for small production runs compared to other manufacturing methods.
Vee blocks are used to securely hold round or cylindrical workpieces in place during machining or inspection operations. Clamps are used to secure workpieces to a work surface or fixture to prevent movement during machining, welding, or other fabrication processes. Both tools are essential for ensuring precision and accuracy in manufacturing and machining processes.
The different classifications for manufacturing processes are casting processes, machining processes, surface finishing processes, metal working processes joining processes, and shearing and forming processes. The processes used to change the physical characteristics of materials are hardening and tempering.
Additive processes involve adding material to the piece. Subtractive processes involve taking material from the piece. Painting is additive because you add paint. Carving is subtractive because you take away pieces from your original block.
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
