      History Of CNC

      How Long Has CNC Existed?

      The first numerical control machines originated in the 1940s. Largely different from CNC equipment as we know it today, these early models included tools with motors attached that relied on punched tape, an old form or data storage.

      By the 60s, the invention of the minicomputer led to a drop in prices, which allowed CNC machines to flourish. Over the years, the affordability continued to rise and the accessibility broadened, making CNC machines popular among domestic toolmakers by the 80s.

      Today, as technology continues to develop, both hobbyists and large industrial operations utilize the efficiency of a CNC machine in a myriad of applications.

      Definition

      What Does CNC Mean?

      The acronym “CNC” stands for “computer numerical control”.

      A CNC machine is a computer-controlled device that can cut, carve and mill programmed designs from wood, MDF, plastics, foams, and metals.

      In the process, a variety of tools are used, often with a wide range of cutting capabilities.

      Application

      How can CNC apply to you?

      From Arts and design to machine parts, a CNC machine can be used for almost anything you want to cut from a wide variety of materials

      The most popular industries for CNC machines:

      • Art (33%)
      • Prototyping (25%)
      • Cabinetry & Furniture (17%)
      • Machine Parts (17%)
      • Signage (8%)

      "Anything you can draw, anything you want to put together,
      it can cut"

      Components Of A CNC Machine

      There are many types of CNC machines for different purposes;
      these are the most common components on CNC machines

      Controller

      The controller completes the link between the computer system and the mechanical components of a CNC machine

      Gantry

      This bridge like structure moves cutting tools in an X/Y coordinate system

      Spindle

      The spindle powers cutting and carving tools on the CNC machine

      Energy Chain

      The energy chain carries the power and signals needed for a CNC machine to complete a job

      Work Table

      This flat work surface secures the materials as they’re being cut. Some work tables have vacuum suction to secure materials in place

      Guide Rails

      These linear motion systems move the gantry in a straight path

      CNC Efficiency

      What makes CNC so efficient?

      Maximizing resource usage with nested manufacturing

      Nested manufacturing maximizes the number of parts that can be machined from a single piece of material by mathematically programming the cuts.

      By arranging the cuts to minify empty space, overall waste can be significantly reduced. Nested machining is the same concept as arranging cookie stamps on rolled out dough to make the most cookies from one roll.

      This efficiency in material usage also promotes environmentally responsible manufacturing

      CNC Machines

      What types of cnc machines are there?

      A variety of machines for a variety of uses

      CNC ROuters

      • The most common type of CNC machine
      • Router-based milling machines
      • Dynamic machines capable of drilling, pocketing, edging, 3D cutting and more
      • Capable of cutting at up to 1200 IPM (inches Per Minute) with rapid movements up to 3000 IPM

      CNC Turners

      • Highly precise cuts at a high velocity
      • Spinning you workpiece against a cutting tool
      • Cuts are made as the machine moves the drill bit laterally until it touches the workpiece

      CNC Plasma Cutters

      • Combine compressed-air gas and electrical arcs
      • Primarily for cutting metals

      CNC CO2 Lasers & Fiber Lasers

      • Two types: CO2 and Fiber
      • Can cut, engrave and etch – Fiber is primarily for engraving on metal
      • Can be used for a variety of materials: wood, acrylic and leather.

      CNC Cost

      How Much Do CNC Machines Cost?

      Prices vary greatly depending on capabilities and size

      Since prices vary according to capabilities and size, the best way to get pricing according to your needs would be to talk with a CNC specialist.

      Most home-oriented CNC machines, like the IQ, are a few thousand dollars. High-end production, or “large industrial” CNC machines can be as much as $100,000, even over that after all accessories.

      The average price sold, though, is right around $15,000. Though this number is high, there are several ways to off-set this cost through financing, government funding, and very low operating costs per hour.
