What Is CNC Machining Wood?

The Definition of CNC Machining Wood

CNC (Computer Numerical Control) machining is a method of manufacturing that involves the use of computers to control the movement of tools and machinery. In CNC machining, a computer program is used to send instructions to a CNC machine, which then uses these instructions to cut and shape materials into a desired final product.

CNC machining can be used to manufacture a wide range of products, including those made from wood. In CNC machining wood, a block of wood is placed into a CNC machine, and a tool (such as a router or a lathe) is used to cut and shape the wood according to the instructions provided by the computer program. This process allows for the precise and efficient production of complex shapes and designs, and can be used to create a wide range of wood products, from furniture and cabinetry to musical instruments and crafts.

How Do CNC Machines Perform Woodworking?

CNC machines perform woodworking by using computer-controlled tools to cut and shape wood into a desired final product. The specific tools and processes used in CNC woodworking will depend on the type of machine being used and the desired end product.

For example, a CNC router is a type of machine that is commonly used for woodworking. It uses a rotating cutter (called a router bit) to cut and shape wood into a variety of different shapes and designs. The router is guided by the computer program, which instructs the machine on the precise movements required to produce the desired product.

Other types of CNC machines commonly used for woodworking include lathes, which use a turning action to shape wood into cylindrical or other curved shapes, and laser cutters, which use a focused beam of light to cut and engrave wood.

Why Use Wood for CNC Machining?

Wood is often regarded as a material easy to machine as a result of how much softer it is than metal. Meanwhile, it’s ideal for CNC machining with its affordability, strength, versatility, and attractive appearance. The reasons why using wood for CNC machining are concluded below:

  • Wood is a widely available and affordable material, making it a cost-effective choice for manufacturing.

  • Wood is strong and durable, and can be used to create a wide range of products, including furniture, cabinetry, and musical instruments.

  • Wood is easy to engrave, bend, compress, or cut and can be shaped and molded into a wide range of complex shapes and designs using CNC machining.

  • Wood is lighter and stronger because of its higher strength-to-weight ratio than that of metals.

  • Wood has a natural, attractive appearance, patterns, and luster, and can be finished in a variety of ways to enhance its beauty and durability.

  • Wood can reflect infrared rays and absorb ultraviolet rays.

What Are the Benefits of CNC Machining Wood?

CNC machining wood is a practical manner to realize tighter tolerance with higher machining speed compared with other traditional manufacturing methods. It’s a highly efficient and cost-effective method of manufacturing wood products, and is well-suited for producing a wide range of products with a high degree of precision and consistency. There are several benefits to using CNC machining to manufacture wood products:

CNC machining allows for precise and accurate cutting and shaping of wood, with tolerances as low as 0.001 inches. This level of precision is difficult to achieve using traditional manufacturing methods.

CNC machining is a highly efficient method of manufacturing, as it allows for the rapid production of large quantities of products with a high degree of consistency.

CNC machines can be programmed to produce a wide range of products, from simple to complex shapes and designs. This versatility allows manufacturers to produce a wide range of products using a single machine.

CNC machining is often more cost-effective than traditional manufacturing methods, particularly for producing large quantities of products.

CNC machining produces products with a high level of quality and consistency, as the machine is able to produce each product with a high degree of accuracy and precision.

CNC machines are employed for a multitude of jobs, and woodworking is no exception. CNC machines can effortlessly cut wood with end mills and router bits.

A CNC router and a lathe can perform milling hardwood like oak, beech, and ebony to create intricate shapes and designs with high precision. For precision woodworking, it is vital that each axis of the machine is stable, since the resistance of hardwood exerts high reaction forces on the entire machine structure. To begin the milling process, the wood is placed on the machine bed and the CNC machine is turned on. The cutting tool is then moved over the surface of the wood, following the path dictated by the programming instructions. As the tool rotates, it removes material from the wood, shaping it according to the design.

The surface of wood needs to be protected from water, light, and potential damage from daily use such as polyurethane, lacquer, oil, etc. Runsom specializes in providing a variety of finishes available for your CNC wood parts.

  • Stain the wood surface
    Oil-based stains are the most popular and accessible type. They penetrate deep into CNC machined wood parts and then offer a durable finish.
  • Varnish the wood surface
    Varnish is a transparent and hard topcoat used to coat wood. Once varnished, it protects the surface and imparts a gloss due to its high solids content while providing UV protection as well.
  • Paint the wood surface
    Lacquer is similar to a vanishing agent and is the fastest and brightest finish for wood surfaces. Lacquer is such a durable finish that can cover any surface in seconds. It’s solvent-based and quick-drying, which means it will dry in minutes without the risk of staining your wood parts.
