The term “CNC” stands for “computer numerical control.” According to the definition of CNC machining, it is a subtractive condition that usually uses computerized controls and industrial machinery to remove layers of fabric from such a stock piece, also known as the “blank” or “workpiece,” to create a custom-designed part.
A variety of industries, including large CNC machining, machine tools of parts, and rapid prototyping for telecommunications, as well as CNC machining aviation parts that also require higher stiffness than other industries, use this process because it is useful for a wide variety of materials, such as metals, plastics, timber, glass, foam, and composites.
Be aware that the definitions of CNC machining and machines differ; one is a process, and the other is a machine.
We at Pangea Technologies are a CNC machining supplier. Our CNC (computer numerical control) machines carry out machining operations according to computer-generated instructions. Machining equipment uses a stock layer of fabric to get the desired results and removes certain portions. A subtractive manufacturing method, such as CNC machining involves removing layers of material to produce the desired shape.
Software for CNC machining types
Software programs are used in the online CNC machining operation to guarantee the accuracy, precision, and optimization of the component or product that has been specifically created for it. Among the utilized software programs are:
Computer-aided designing (CAD) software creates 2D vector or 3D solid component and surface representations and the required technical documentation and part requirements. A CAM program often uses the plans and models a CAD application produces to develop the machine program required to make the component using a CNC machining technique.
Additionally, CAD software is useful for defining and evaluating the best component qualities, assessing and validating part designs, simulating items without needing a prototype, and giving design information to manufacturers.
Computer-aided manufacturing (CAM) technology is used to build the machine code required to operate the CNC machine or manipulate the tooling to produce the made-to-order item by extracting technical data from the CAD model.
The CNC machine may operate independently of an operator thanks to CAM software, which can also automate the final product assessment.
CAE Software used by designers during the pre-process, analysis, and post-process stages of the development process is known as computer-aided engineering (CAE).
In architectural analysis applications, including design, simulation, planning, production, diagnostics, and repair, CAE software is utilized as an additional support tool to assess and revise product design. Finite element analysis (FEA), fluid mechanics (CFD), and multi-body dynamics (MDB) software are examples of the several types of CAE software that are available.
Some software programs incorporate all CAD, CAM, or CAE software features. With this integrated program, also known as CAD/CAM/CAE software, the complete manufacturing process—from design to evaluation to production—can be managed by a single piece of software.
CNC Machining Operations Types
CNC machining is a manufacturing method that can create many items, including car chassis, surgical equipment, airplane engines, gears, or hand and garden equipment. It is suited for various sectors, such as automotive, aerospace, building, and agriculture.
Certain operations are listed below:
CNC Drilling
Multi-point drill bits are used in the machining process of drilling to create cylindrical holes inside the workpiece. To generate vertically aligned holes with sizes equal to the drill bit used for the drilling operation, CNC machines normally feed the spinning drill bit perpendicularly to the workpiece’s surface.
But specialized machine setups and work holding equipment can also carry out angular drilling operations. Counterboring, countersinking, reaming, or tapping are all operational aspects of the drilling process.
A CNC milling
The machining process known as milling removes the material from the workpiece using spinning, multi-point cutting tools. In manual milling, the machine supplies the workpiece inside the reverse way to the rotation of the cutting tool; however, in Computer numerical control milling, the CNC machinery normally feeds the workpiece towards the cutting tool in much the same direction as that of the cutting tool’s rotation.
The process has two operational capabilities: face milling, which creates shallow, flat surfaces or flat-bottomed cavities in the workpiece, and peripheral milling, which creates deep holes, such as slots, and threads, in the workpiece.
CNC turning
Single-point cutting tools are used in turning machining to remove items from the revolving workpiece. To generate cylindrical parts with internal and external features, including slots, tapers, and threads, a CNC turning contraption uses a CNC lathe machine—to feed the scalpel blade in a linear motion all along the surface of the rotating workpiece. This process continues until it has grown to the appropriate diameter.
The operations of boring, facing, grooving, and thread cutting can be performed during the turning process. With its revolving cutting tools, the CNC mill performs better for more complicated pieces than the CNC lathe. Lathes, on the other hand, produce round items more quickly and accurately due to their spinning workpieces and fixed cutting tools.
Process Overview for CNC Machining
CNC machining machines use computerized controls to operate and manipulate machines and laser cutting to shape stock material—for example, metal, plastic, wood, foam, matrix, etc.—into unique parts and designs. CNC machining evolved from the arithmetical control (NC) process, which used punched tape cards.
Although CNC machining provides a variety of capabilities and activities, its core principles apply to all of them relatively uniformly. The following steps are part of the fundamental CNC machining process:
- the CAD model’s creation
- CNC program creation from the CAD file
- Getting the CNC machine ready
- the machining operation is carried out
