How Do Different Types of CNC Machines Work?
The Functionality of CNC Milling Machines
CNC milling machines use G-code or other computer-generated codes programmed into the machine’s software. A rotating cutter eliminates material from the workpiece, which rotates on the three axes X, Y, and Z for better figures and measurements. Most modern CNC machines now have machining simulation software to produce a virtual prototype of the machine’s operation before physical mass production starts.

Understanding CNC Lathes and Their Uses
CNC lathes can make it possible to shape a workpiece—most commonly plastic or metal—by rotating it against the cutting tool set in place, which aids them in specializing in turning functions. Drilling, turning, or any other computer-coded operation of CNC lathes can be regarded as complex undertakings that can be thoroughly automated to yield precision. The specific use of lathes, as opposed to milling machines, which only use rotary cutters, is that lathes rotate the workpiece while stationary tools cut it. This technique is superbly effective in making rotationally symmetric parts such as shafts and pulleys. At the same time, CNC lathes have excellent potential as they are computer-generated and can rotate as one, producing multiple parts quickly with great accuracy. Due to such characteristics, these machines are irreplaceable in automotive, aerospace, and other industrial production centers that deal with precise parts.
The Role of Electrical Discharge Machining
EDM holds an exceptional position in the class of manufacturing processes because it allows the machining of precise zones on hard materials and complex shapes, which were impossible to achieve with traditional cutting tools. EDM works through a series of electric sparks that erode material from the workpiece. Hence, it is ideal for machining less steel and complex alloys. It does not require applying any cutting forces on the material, which might cause deformation in the weak parts. EDM is capable of producing parts where the bulk of the dimensions are in microns and possesses features that are very close to the best tolerances, making such parts applicable in aerospace, medical, and electronics industries where complex shapes and features are a significant requirement. Furthermore, EDM is interested in making micro features and good surface finishes, which gives the manufacturers a lot of scope to play around.
