CNC or Computerized Numerical Control is a computerized manufacturing process in which the movement of production equipment is controlled by the pre-programmed software and code. A range of complex machinery that is used for shaping, cutting, and creating diverse parts and prototypes is controlled by CNC machining. CNC machines produce a variety of metal and plastic parts, as they can turn a metal sheet into an automobile part. CNC machine is a high-speed, reliable, and fast machine that precision cut parts with intricate shapes and provides brilliant repeatability. It uses dedicated tooling to create diverse shapes and sizes of parts.
The process of CNC cutting initiates with a designer creating a drawing on a computer with the help of software as per the customer’s specification. Using this drawing, a CNC programmer will transform it into a workpiece with the support of CAM software. With the help of the CAM software, the programmer creates a toolpath and generates the G-code that controls the CNC machine. The program is then sent to a CNC machine by the computer that interprets the design. The cutting tool of the CNC machines moves side-to-side along an ‘X-axis, in and out along the ‘Y-axis, and up and down on the ‘Z-axis. The tool cuts and moves along all three axes simultaneously.
History of CNC Cutting
CNC machines may be a mainstay of the modern manufacturing and production sector but their history dates back to the 1940s when the first numerical control machines emerged. The idea that has been around for some time was first developed in 1949 by John T. Parsons, a computer pioneer, who developed it as a part of the Air Force research project. It was an experimental milling machine built with the goal to use motorized axes to produce helicopter blades and stiffer skins for aircraft. Parsons work on the first system by using an IBM 602A multiplier to calculate airfoil coordinates. The data was fed into a Swiss Jib borer with the help of feeding punched cards into the system and the preprogrammed information was used to produce helicopter parts. This was the start of CNC machine programming.
Difference between CNC and Laser Cutting
CNC cutting is a contact-based cutting process that is used in the fabrication of precision parts and components for the manufacturing sector. CNC cutting is a relatively low-cost process, as CNC machining is quite affordable and hence it is popularly used in a number of different industries for a long time. CNC cutting is used to create a design based on the customer’s need with the help of software like AutoCAD or CorelDRAW. Once the drawing is finalized, a piece of metal or other material is placed on the cutting surface. The CNC machine receives a signal from the computer and then interprets the design. The operator processes multiple products with the help of a prototype that meets all requirements. In the CNC cutting, the tool moves side-to-side and back and forth along the three axes while following the shape of the design.
The laser cutting machine is also guided by a CNC system just like the CNC cutting machine, with the only difference in the process in which the cutting occurs. In the laser cutting heat is used to create the desired shape of the product in place of a cutting tool. Laser cutting relies on a high-energy light beam that burns through the metal or other material to create a shape. However, laser cutting is not suitable for every application. The laser cutting process works by directing a high-powered laser output through optics. In other words, it can be said that CNC cutting is achieved through friction whereas laser cutting is achieved through heat. With laser cutting, one has a high level of precision and intricacy, as one has excessive control of a laser cutter that allows one to be incredibly creative with the cuts.
Benefits of CNC Cutting
Automation has played a major role in the manufacturing industry with advanced and modernized data-driven tools and equipment line CNC machining that drive innovation. CNC cutting is a culmination of high-paced activities resulting in precision-made components that give businesses a competitive edge. It helps businesses create parts that could not be reproduced profitably by any other manufacturing method. The various advantages of CNC cutting include:
- Little to No Waste– CNC cutting is carried out using software programs that undergo iterative optimization and develops the best way to create a component or a part without any waste.
- Greater Accuracy and Zero Defects– CNC cutting is autonomously carried out without any manual intervention, there is no possibility of human errors in the manufacturing process that might lead to defects. With the cutting process governed by codes and software programs, this process delivers parts of greater accuracy.
- Efficient and Faster Production– CNC cutting when carried out with milling machines leads to efficient and faster production because this machine can operate on the fastest settings to fulfill the increased demands. Besides, this machine can operate 24 hours a day and seven days a week without any break while still maintaining a high degree of accuracy without wasting any material resources.
- Works with Different Materials– CNC cutting can be performed on different materials from wood, foam, metal, steel, plastic, acrylic, to many more. Besides, this also proves effective when a single design is required to be cut repeatedly. With CNC cutting machines a single design can be cut repeatedly with utmost accuracy.
Why is CNC Cutting Popular in the USA and Canada?
CNC cutting is extremely popular in countries like U.S. and Canada because it is a relatively low-cost process when compared to laser cutting. The cost of purchasing a CNC machining is comparatively low compared to a laser cutter so it turns out to be economical. The power consumption of CNC machining is also low making it an affordable option for a laser cutter. Besides CNC cutting makes diagonal, curved, and straight-line cuts incredibly easy because the machine is programmed to make the cuts and it is not done by hand using a saw or similar tool, so any chance of human error is completely eliminated. CNC cutting is also popular in these countries because it is a connection base cutting procedure that manufactures precise parts with apt positioning and velocity. CNC cutting produces multiple products using thick materials and it facilitates better control over the depth of cut. It also gives no discoloration and enables manufacturers to produce three-dimensional cuts.
