CNC machining has become increasingly popular in today’s manufacturing world. CNC or Computerized Numerical Control is a computerized manufacturing process in which the movement of production equipment is controlled by pre-programmed software and code. CNC machines, generally called computer-controlled machining systems, enable companies and firms to automate various industrial activities otherwise done manually. The CNC-driven machines are extensively being used for:
- Reducing waste
- Eliminate typical human errors
- Increase the output
CNC machining is used to control a variety of complex machinery, including grinders, lathes, and turning mills, which are all used to cut, shape, and manufacture various components and prototypes. CNC machinists use mechanical design, technical drawings, mathematics, and computer programming skills to create a variety of metal and plastic parts on a daily basis. The operators can transform a piece of metal into an aeroplane or vehicle component. Unlike the old, unsafe factory equipment of the past, today’s design and mechanical parts for CNC systems are highly automated. Computer-aided design (CAD) software is used to describe the mechanical dimensions of the elements, which are then converted into manufacturing directives using computer-aided manufacturing (CAM) software. Therefore, having knowledgeable CNC machinists and programmers in the business to handle this high-tech machinery is critical. Computer numerical control (CNC) machines are widely utilized in manufacturing and have become more functional and applicable in recent years. These machines make a wide variety of products using actuators, software programmes and motors. Let’s have a look at some various types of CNC equipment.
CNC Milling Machine
This machinery is one of the most prevalent CNC machines with built-in drilling and cutting tools. The material is drilled or cut out by the computer. The majority of CNC milling machines come in 3- to 6-axis variants. This machine produces spur gears, as well as drills the workpiece bore. It also makes slots using a component programme inserted into the system. It is uncomplicated to operate for a semi-skilled employee also. A capstan and turret are examples of mass-produced items. However, there is no pre-programmed feeding system. These machines deliver items with highly tight dimensional tolerances.
Laser Cutting Machines
These Laser-cutting CNC machines cut through the rigid materials, but instead of a plasma torch, they utilize a laser to do so. The lasers are extremely precise and accurate, although they aren’t as effective as plasma torches.
CNC Routers
The CNC routers machines cut and dissect many types of materials like metals, high-density foam, wood, steel etc. These routers usually work in three directions X, Y, and Z-axis. The X-axis runs through the front from back and is the longest one, while the Y-axis works from the left to right direction, and the Z-axis is cut from up and down. These routers work very efficiently and conveniently than manual force. Their work is accurate and done precisely, eliminating every possible error.
Edge-Banding
Edge banding is a method of finishing carpentry. A short strip of any chosen material is used to make durable and robust trim edges equally accurate and eye-pleasing. This technique is used to cover the exposed edges of plywoods, boards, MDF and smooth the surface by giving it a solid appearance.
