Machining refers to complex and manifold measures by which raw material is cut to shape it into any desired size and shape with the application of a highly controlled material-elimination process. The entire ball game with common themes and the controlled approach to eliminate material is collectively called Subtractive Manufacturing. This feature a prominent distinction with the process for the controlled addition to material, which is called additive manufacturing. Though the exact description for the term “controlled” is likely to vary from one application to another, however, it usually refers to the application of machine tools, like Swiss machined parts, besides the power and hand tools.
Various Forms of Machining Operations
The 3 major machining process can be categorized as turning, milling, as well as drilling.in addition, there can be an additional category that will account the scopes of actions like shaping, boring, planning, sawing, as well as broaching.
As for the tuning operations, it involves those processes that feature the rotation of the workpiece as the primary approach to move metals against the involved cutting tool. Lathe happens to be the principal machine tool that is applied in this form of machining.
As for milling operations, the process features the rotation of the cutting tools which is done with the objective to bring the cutting edge that bears against the concerned workpiece. Milling machines happen to be the application utilized in these instances.
As for the 3rd category, drilling operations will involve all those activities that aim to produce holes along the lower extremities, featuring a contact with the workpiece involved. Though such operations are primarily concerned with drill presses, however, It is observed in the mills and lathe as well.
The 4th category will include all those steps that are executed without the production of swarf. Burnishing is the most typical example that will come in this category of machining.
Any unfinished workpiece that requires any type of machining work, even if it is Swiss precision machining, will inevitably feature a portion of the material being cut away. This is done to create the finished product, which is basically a workpiece that complies with the set specifications as per the engineering drawing. All the steps discussed above are the inevitable component of the overall machining process, and the overall accuracy and efficiency in the process are determined by the perfection at these stages. Though a machine shop features stand-alone operations, usually, businesses opt for internal machine shops to complement the specific business needs.
