General machining processes include turning, shaping, milling, drilling, sawing, abrasive machining, and broaching.
Machining process is a broad term that refers to the cutting processes, abrasive processes and the non-traditional machining processes.
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.
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.

Neither the tool or the workpiece rotate
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.
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
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.
The mass of material lost in a typical machining process depends on various factors like the type of material being machined, the cutting parameters, and the machining method used. In general, only a small percentage of the original material is lost as chips or swarf during machining, with the majority of the material being converted into the desired workpiece.
If someone wanted to find some Plastics Machining products, there are a variety of places where someone can do so. Some of these places are First Cut and Metal Tech.
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.
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.
