In CNC turning , the machine—typically a CNC lathe machine —feeds the cutting tool in a linear motion along the surface of the rotating workpiece, removing material around the circumference until the desired diameter is achieved, to produce cylindrical parts with external and internal features, such as slots, tapers, and threads.

Operational capabilities of the turning process include boring , facing, grooving, and thread cutting. When it comes down to a CNC mill vs. However, lathes, with rotating workpieces and stationary cutting tools, work best for faster, more accurate creation of round parts. Close cousins to lathes, CNC spinning lathe machines involve a lathe set with a blank a metal sheet or tube that rotates at high speeds while a metal spinning roller shapes the workpiece into a desired shape.

Swiss machining , also known as swiss screw machining, uses a specialized type of lathe that allows the workpiece to move back and forth as well as rotate, to enable closer tolerances and better stability while cutting. Workpieces are cut right next to the bushing holding them instead of farther away. This allows for less stress on the part being made. Swiss machining is best for small parts in large quantities, like watch screws, as well as for applications with critical straightness or concentricity tolerances.

You can find out more about this topic in our guide on how swiss screw machines work. It is not quite a 5-axis mill , however, because the fourth and fifth axes do not move during machining operations. Adding servomotors to the additional axes, plus the computerized control for them — the CNC part —would make it one.

The two additional axes can also be incorporated at the machining head, or split — one axis on the table and one on the head. To handle a CNC lathe , a machinist should have completed a set amount of coursework and earned appropriate certification from an accredited industrial training organization. CNC turning machining training programs will usually involve multiple classes or sessions, offering a gradual instruction process broken up into several steps.

The importance of adhering to safety protocols is reinforced throughout the training process. Beginning CNC lathe classes might not include hands-on experience, but they may include familiarizing students with the command codes, translating CAD files, tool selection, cutting sequences, and other areas. A beginner CNC lathe course may include:.

Later CNC lathe training typically involves actual lathe operation, as well as machine adjustments, program editing, and the development of new command syntax. This type of lathe machine training can include courses on:. Other mechanical CNC machining operations include:. As indicated above, there is a wide range of machining operations available.

Depending on the machining operation being performed, the CNC machining process employs a variety of software applications, machines, and machine tools to produce the desired shape or design. The CNC machining process employs software applications to ensure the optimization, precision, and Cnc Professional Machine And Engineering Co accuracy of the custom-designed part or product. Software applications used include:. CAD : Computer-aided design CAD software are programs used to draft and produce 2D vector or 3D solid part and surface renderings, as well as the necessary technical documentation and specifications associated with the part.

The designs and models generated in a CAD program are typically used by a CAM program to create the necessary machine program to produce the part via a CNC machining method. CAD software can also be used to determine and define optimal part properties, evaluate and verify part designs, simulate products without a prototype, and provide design data to manufacturers and job shops.

CAM : Computer-aided manufacturing CAM software are programs used extract the technical information from the CAD model and generate machine program necessary to run the CNC machine and manipulate the tooling to produce the custom-designed part. CAM software enables the CNC machine to run without operator assistance and can help automate finished product evaluation. CAE : Computer-aided engineering CAE software are programs used by engineers during the pre-processing, analysis, and post-processing phases of the development process.

CAE software is used as assistive support tools in engineering analysis applications, such as design, simulation, planning, manufacturing, diagnosis, and repair, to help with evaluating and modifying product design.

Depending on the machining operation being performed, the CNC machining process employs a variety of CNC machines and machine tools to produce the custom-designed part or product. While the equipment may vary in other ways from operation to operation and application to application, the integration of computer numerical control components and software as outlined above remains consistent across all CNC machining equipment and processes.

Drilling employs rotating drill bits to produce the cylindrical holes in the workpiece. The design of the Cnc Professional Machine And Engineering Company drill bit allows for the waste metal—i.

There are several types of drill bits, each of which is used for a specific application. Types of drill bits available include spotting drills for producing shallow or pilot holes , peck drills for reducing the amount of chips on the workpiece , screw machine drills for producing holes without a pilot hole , and chucking reamers for enlarging previously produced holes. Typically the CNC drilling process also utilizes CNC-enabled drill presses , which are specifically designed to perform the drilling operation.

However, the operation can also be performed by turning , tapping , or milling machines. Milling employs rotating multi-point cutting tools to shape the workpiece.

Milling tools are either horizontally or vertically oriented and include end mills , helical mills , and chamfer mills. The CNC milling process also utilizes CNC-enabled milling machinery , referred to as mill machines or mills, which can be horizontally or vertically oriented. Basic mills are capable of three-axis movements, with more advanced models accommodating additional axes. The types of mills available include hand milling, plain milling, universal milling, and omniversal milling machines.

Turning employs single-point cutting tools to remove material from the rotating workpiece. The design of the turning tool varies based on the particular application, with tools available for roughing, finishing, facing, threading, forming, undercutting, parting, and grooving applications.

The types of lathes available include turret lathes , engine lathes , and special-purpose lathes. Companies that specialize in manufacturing CNC machines often offer a desktop series of smaller, lightweight machines. Desktop CNC machines , although slower and less precise, handle soft materials well, such as plastic and foam.

Machines featured in a tabletop series resemble the larger industry standard, but their size and weight make them better suited to small applications.
