SOFTWARE FOR CNC MACHINING

Traditional CNC machining is old. Manufacturing has changed so should your tools. Stop struggling with broken processes and data management in your CNC software – do what you do best.

What is CNC machining?

CNC stands for computer numerical control. There are many types of CNC machines, and this is often the main step in the process of creating a component or part through material removal. Once a part has been designed in CAD software, CAM (computer aided manufacturing) software is used to generate toolpaths, plans that tell a CNC machine how to move.

Fusion 360 for CNC machining

Packages like Fusion 360 integrate CAD and CAM to keep these processes more connected. Then the CNC machine is prepared by loading in stock material, the piece to be cut, as well as any tools that might be used during the machining process. Finally, the toolpaths are converted into code that controls the machine motion and creates the final part.

Types of CNC machining

ROUGHING

The first step in many CNC machining operations is to remove as much material as possible. See how Autodesk's Adaptive Clearing helps.

2 AXIS VS 3 AXIS MILLING

Learn how 2 axis milling compares to 3 axis, and the advantages that 3 axis CNC machining has to offer. 

3+2 AXIS MACHINING

Positional 5-axis, or 3+2, can offer many of the advantages of simultaneous 5-axis without the additional complexity or high cost.

TURNING

Turning, while still CNC machining, is quite different from milling. Find out how.

CNC machining milling styles

CNC machines are broadly classified by the number of axes involved and how they move.

  • 2.5 axis cnc machine

    2.5 AXIS

    2.5-axis milling creates prismatic features at distinct Z levels. Even though the machine is only moving in 2 axes simultaneously, the CAM software is still used as the shapes created can be complex and high precision.

  • 3 axis cnc machine

    3 AXIS

    3-axis milling uses all three axes simultaneously. Software is used to generate these toolpaths since the surfaces are often complex.

  • 4 axis cnc machine

    4 AXIS

    4-axis milling adds one rotational axis to 3-axis milling. This is useful when parts are near cylindrical and can be used to create complex geometry or access multiple parts around workholding like a tombstone.

  • 5 axis cnc machine

    5 AXIS

    Simultaneous 5-axis machining uses all 5 axes at the same time to allow milling of complex shapes at high precision. CAM software is all but required to program these CNC machines, as the motion is very complicated.

Types of CNC machines

CNC machine design will vary greatly. On some machines, the part will move or rotate while the spindle and tool remain stationary. In other machines, the part is stationary while the spindle moves. Some machines are a combination of both these designs.

FAQs on CNC Machining

Find answers to frequently asked questions about CNC machining software.

  • How much does CNC machining cost?

    Typically, one of the largest costs associated with CNC machining is the CNC machine itself. Entry level machines start around $5,000 with high end machines reaching upwards of $500,000. The cost depends on factors like size, power, spindle speed, multi-axis capabilities, and accuracy. Once you have a machine, you will need to purchase cutting tools to machine parts. To generate the instructions required for CNC machining, it’s common to subscribe to a computer aided manufacturing (CAM) software as well. So, while there’s no one size fits all answer, CNC machining requires some up-front investment to get started.

  • What is the difference between CNC machining and milling?

    Milling is one style of CNC machining. CNC machining is any process where a part is manufactured by a machine that is controlled by a computer. In milling, a cutting tool spins at high speeds and advances into or across the work piece to remove material. Other types of CNC machining include turning, routing, plasma cutting, and water jetting. Turning and milling can be combined into a single machine, as can additive and subtractive operations, creating even more complex styles of CNC machining.

  • How is CNC machining different from 3d printing?

    3D printing, or additive manufacturing, is the process of depositing layers of material to build up the desired geometry. Generally speaking, CNC machining is used to refer to subtractive processes, where material is removed from the work piece, resulting in the desired geometry. While 3D printing processes can create more complex geometry like internal latticing, parts must also be supported during the printing process to prevent failure. CNC machining generally produces more accurate parts and can be significantly faster, especially when manufacturing single parts.

  • How does CNC machining work?

    CNC stands for Computer Numerical Control, which means that a computer controls what the machine does, including but not limited to the spindle speed, feed rate, position. In order to program the computer, often called a control, a person can use computer aided manufacturing (CAM) software. CAM software generates a series of instructions called toolpaths and then generally uses a post processor to translate that toolpath data into code the machine can read. Then a person would transfer that code onto the machine and run it to produce their final part.

  • Can I use Fusion 360 to CNC?

    Yes! Fusion 360 includes a powerful and easy to use CAM solution that can control a wide variety of CNC machines including mills, lathes, routers, mill/turn machines, plasma cutters, water jets, and lasers. Fusion 360 also integrates CAD, CAE, and ECAD along with CAM into a single solution to reduce data loss and improve process reliability for CNC machining and other downstream processes.
