CNC drilling and milling machines are typically capable of moving cutting tools and/or workpieces along several different axes of motion.
1. CNC stands for "Computer Numerical Control".
CNC machining is a type of machining that is widely used in manufacturing applications, but what exactly does it do to achieve the various actions of a CNC drilling and milling machine CNC machining can be used to machine parts made of many different materials, such as a variety of metals and plastics, etc. 2.
2. CNC drilling and milling machines are programmed using a language called G-code.
CNC machining uses special CNC software and a programming language called G-code in order to control all aspects of the movement of the CNC drilling and milling machine in order to create an object that is machined on demand. the G-code commands control the speed and position of the cutting tool with respect to the workpiece, the feed rate of the material to the tool, and many other factors.
3. It all starts with CAD
The process usually starts with a 2D CAD (Computer Aided Design) drawing or 3D CAD model. G-code is then derived from this and an air test programme is carried out. This is called "cutting air" and is used to avoid irreversible situations that could lead to damage to the workpiece or cutting tool. If the test is satisfactory, the programme can be run to act on the part to be machined. 4.
4. CNC drilling and milling machines provide accuracy and repeatability
CNC drilling and milling machines can be used to make complex three-dimensional shapes as individual parts. It offers higher accuracy than manual machining. Most importantly, it is repeatable. The same set of CNC programmes can be used time and time again to make the same batch of parts.
5. Use CNC to make any part you can imagine!
CNC drilling and milling machines are typically capable of moving cutting tools and/or workpieces along several different axes of motion. 3-axis CNC drilling and milling machines can move in the X, Y, and Z axes to produce a three-dimensional shape, which is the basic model. More advanced 4-axis CNC machines introduce a 4th axis of rotary motion parallel to the X-axis, allowing more complex objects to be produced. It is also possible to use 5 or even 6-axis machines that can produce almost any shape imaginable.
