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.
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.
HYBRID MACHINING, AS FAR AS OUR MANUFACTURING OF FASTNERS MACHINERY TO MAKE A SINGLE PRODUCT OUT OF TWO OPERATIONS OR TWO DIFERENT RAW MATERIAL IS CALLED AS HYBRID MACHINING egsample BIOMETAL RIVET.
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.
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
A manufacturing tolerance chart can be defined as a graphical representation of a sequence of metal removal operations. Such a chart provides the raw material dimensions, the rough cut, semi finish and finish machining dimensions for each machining operation along with the machining tolerances, stock removal amounts for each cut and the resultant finish dimensions and tolerances. These charts were used for many years to help produce cost effective processes that provided the most liberal machining tolerances while meeting the B/P requirements. In recent years, because of increased machining accuracy, the tolerance chart is frequently ignored and processes are developed more by trial, error and experience.
