A computer numerically controlled machine tool, is an automated machine tool equipped with a program control system. This control system is capable of logically processing a program with control codes or other symbolic instructions specified and decoding it so that the machine moves and machines the part. Do you know CNC machine tools?
This passage is going to talk about the followings of CNC cutting machine:
1) What is CNC?
2) What is a desktop CNC?
3) Application of desktop CNC cutting machine
CNC - Computerized Digital Control - uses digital data, computers and CAM programs to control, automate and monitor the movement of the machine. The machine can be a milling machine, lathe, router, welder, grinder, laser or waterjet cutter, sheet metal stamping machine, robot or many other types of machines. For larger industrial machines, the computer is typically an on-board dedicated controller. But for more hobbyist types of machines, or with some modifications, the computer can be an external PC. CNC controllers work with a series of motors and drive assemblies to move and control the machine axes to perform programmed motions. On industrial machines, there is usually a complex feedback system which constantly monitors and adjusts the speed and position of the tool.
A Computer Numerically Controlled (CNC) router is a computer controlled cutting machine who’s usually mounted as a handheld router as its used to cut a variety of materials such as spindle wood, composites, aluminum, steel, plastic, glass, and foam. CNC cutting machines can perform the tasks of many woodworking shop machines, such as panel saws, spindle formers, and boring machines. They can also cut joinery, such as mortises and tenons.
CNC routers are very similar in concept to CNC milling machines. Instead of manually routing the toolpath, it is controlled by computerized digital control. CNC routers are one of many tools with CNC variants.
There are many smaller models making hobbyist style desktop CNC machines. They are generally lighter in weight, less rigid, less accurate, slower and cheaper than their industrial counterparts, but can work well with softer materials such as plastic, foam and wax to machine objects. Some desktop machines may operate like printers. Others have their own closed command systems and may even have dedicated CAM software. Some will also accept standard G-code as input. Some industry standard desktop machines do exist with dedicated controllers for performing small, precise jobs.
CNC cutting machines can be used to produce items such as door carvings, interior and exterior trim, wood panels, signs, wood frames, lines, musical instruments, furniture and more. In addition, they see industrial use in plastic thermoforming through an automated trimming process. CNC routers can help ensure that parts are repeatable and efficient enough to produce output, or allow for one-off designs. This is the engraving machine.
