Let us proceed further to understand which type of wood is best for cutting and how beautifully does CNC wood carving machine produce antique furniture.

2. Types of Wood For CNC Routing

Wood is a very common material. Whether you are using materials like plywood, softwood, hardwood, MDF, chipboard or timber, CNC router wood router machine work wonders.

It can easily process the aforementioned wooden materials for the production of cabinet parts, furniture, dovetail drawers, mantle, decorative carving, etc.

2.1 Hardwood for CNC Routing

Hardwoods typically come from what is known as a deciduous tree. This tree has broad leaves which fall in the harsh winter months. Some examples of hardwood are given below:

  • Ash: heavy, lots of rings, light in color

image

  • Beech: strong wood, stiff, shock resistant, has small pores, light in color

image

  • Birch: light in color, has a wavy grain, stiff

image

  • Cherry: strong, light red/brown wood, resists warping,  good for carving

image

  • Elm: Light brown color, low decay resistance, tough

image

  • Maple: one of the hardest woods, resistant to shock,  has even pores and grain

    image


  • Mahogany: strong, reddish-brown in color, even pores, indistinct rings, good for carving

Mahogany

  • Oak: light in color, heavy in weight, strong, prominent ring grain

image

  • Walnut: brown in color, strong, durable, straight grain in the trunk, wavier grain closer to the roots

image

Maple and cherry are the most ideal types of hardwood over oak and poplar that are used for cutting, carving, and etching. They are denser, less fibrous, and subjected to lesser tear-out.

Hardwood is considered as a good option to experiment and CNC wood cutting machine will bring your designs to life in a matter of minutes.

2.2 Softwood for CNC Routing

Softwoods in most cases come from coniferous trees. Coniferous leaves are “needle-like” rather than the broad-leafed deciduous trees. These needles are designed to retain moisture all year round and thus coniferous trees do not shed their foliage in the winter.

Some types of softwoods are harder than many hardwoods.

  • Cedar: Red/brown colored wood, many knots, aromatic

image

  • Cypress: Has many knots, not particularly strong, good decay resistance

image

  • Fir: Even, consistent patterning, easy to work with

image

  • Pine: Pale in color, resistant to shrinking, light in weight


image

  • Yew:Harder softwood, straight grain, medium strength, low stiffness, good decay resistance

image

  • Spruce:Harder softwood, not resistant to decay, light in weight

image

  • Redwood: More resistant to decay from sunlight

image

There are some types of softwood that are much harder than the hardwood. Hardwoods are majorly used for making furniture, flooring, and construction components.

Hardwood grows slowly and costs more than usual. While both the types of wood catch fire but hardwood has greater fire resistance.

3. What are the Types of CNC Bits and Mills Used for Cutting Wood Parts?

Router bits are considered as one of the primary tools for cutting different wooden parts with wood CNC router machine. Bits mainly determine the kind of carving that is necessary but choosing an accurate bit for carving can be confusing as there are lots of variables to consider while using the CNC router for cutting wooden parts

Many manufacturing firms use an especial bit for a different type of material they choose for producing end-product. It can beautifully carve and engrave wood at a high speed maintaining accuracy with consistent results.

In addition, you can save a lot of time and cost incurred in creating beautiful woodwork.

Let us see what type of bits and mills are used by CNC wood router for cutting wood designs:

  • If you are trying to make straight cuts in plywood, you should seek good quality spiral cutting end-mill for carving and etching intricate designs. Since end-mills come in different diameters, you can either choose to upcut or downcut the wood.

  • If you are looking for etching 3D designs on the material then you should be using ball nose bit that has the appropriate size for the level of detailing that you require in the model. Ball nose bits are used to carve fantastic 3D shapes using the tip of the bit to give great detail and smooth contours. You can also use a tapered ball nose bit for intricate 3D carving.

  • For sign cutting, badge making, acrylic engraving, etc., you will need a V bit, V-carving bits, V-groove bits, or engraving bits. Since they are available in a different shape; the most useful angles are 60, 90, and 30 degrees. These high precision sign cutting bits are designed with greater versatility and used for high-precision cutting of heavier flexible and semi-rigid materials.

  • Moreover, if you are looking for bits for flattening boards, then you should use spoil board cutter or fly-cutter bits for a smooth and flat finish. These bits carefully skim the surface of the material giving a flat and shiny surface to the model. If you are using plywood or laminate material, the bits are designed in such a manner that they won’t mangle the outer veneer layer while bits used for plastics are designed specifically to avoid excessive melting. Also, there are many bits used for various applications but you don’t have to buy all 30 bits if you are prototyping the project.

One very important point that you should consider while choosing a bit is that the bit must be short and stout to produce cleaner and smooth cuts.

Using excessively bigger or longer bits leads to vibration bending of the bit while carving the wood with woodworking CNC router.

Moreover, if you intend to cut or carve a large amount of material, smaller bits will give you best results but they should be sharper enough for smooth and nice cuts as compared to dull bits.

4. What are the Tips and Techniques Followed by a CNC Machine for Cutting Wood

CNC routing machines have been considered as one of the powerful tools for designing and construction industries.

CNC routing machine possesses all essential tools that are necessary for carving, etching and different designing purposes. 3D cutting, etching, carving, etc., are the most impressive capabilities that a CNC router entails.

Let us take a look at the tooling techniques to improve the operation of the CNC router:

  1. Smaller Tool: Select a tool that is shortest in the overall length. A high level of rigidity is maintained ensuring the best performance of the operator.

  2. Proper Rotational Direction: When cutting or etching the material, the tool must rotate in a proper direction so that the finished product looks good.

  3. Match the Diameter of the Tool: The diameter of the tool and the thickness of the material cannot be overlooked. When an operator is in the process of cutting, with every rotation the material is resisting the tool. The operator must access the project based on the material being cut.
