What is CNC machining?
Computer numerical control (CNC) machining is a subtractive manufacturing process that uses a machine tool to remove portions of material from a workpiece until the desired shape is achieved. CNC equipment utilizes a computer program (also known as G-code) to control the sequence in which the CNC machine tool or workpieces move relative to each other to create the desired part. Standard CNC machines include multi-axis CNC mills, lathes (or turning machines), and routers. While all CNC machine types rely on computer instructions to perform subtractive manufacturing, their modes of operation differ slightly.
Benefits of CNC Machining
- Improved accuracy and repeatability
- Increased efficiency and productivity
- Reduce waste and material usage
- Consistency in quality and dimensions
- Improved safety and reduced manual labor
- Increased versatility and ability to produce complex shapes
- Flexibility to produce small or large batches
- Improved precision and surface finish
- Minimized downtime for setup and tool changes
- Increased cost effectiveness over time.
Tips for Precision Machining
Avoid holes that are too deep
The effective cutting edge length of the milling cutter is limited, and the correct hole depth design can help reduce machining time and machining costs.
Limit thread depth
Sometimes deep threads are not needed at all. It is usually best to design the thread depth to be 1.5 to 3 times the diameter of the threaded hole.
Avoid excessive tolerances
Note that overly tight tolerances will increase machining difficulty and cost. Therefore, narrow tolerance requirements should only be specified when necessary.
Standard size holes
Standard size holes can be CNC machined with standard drills with high accuracy and speed. This can save machining costs compared to non-standard size holes.
Avoid excessive aesthetics
Putting the accuracy of necessary features above aesthetics will help improve your design because aesthetic requirements can be achieved through fine machining.
Avoid thin walls
Thin-walled parts are more difficult to precisely machine, and to reduce machining costs, the minimum thin wall thickness for metal parts should be 0.8mm, and the minimum thin wall thickness for plastic parts should be 1.5mm.
Avoid features that are too small
Features that are too small, such as those with a diameter less than 2.5mm, will increase the difficulty and cost of machining, so they should be avoided unless necessary.
Correct thread size
It is recommended to use thread sizes of M6 or above, and it is also important to avoid using thread sizes less than M2, and it is also important to avoid designing holes that cannot be tapped.
Alternatives to CNC Machining Services
While CNC machining services are suitable for manufacturing many types of parts, they also have limitations. For example, it cannot be used to manufacture complex internal features, such as internal cavities or arched cooling channels. If your design has these features, you may choose to manufacture them through additive manufacturing methods such as metal or plastic 3D printing. In addition, for certain types of flat workpieces, laser cutting, water jet cutting, wire cutting, and photochemical etching may be more effective.
