What is the Difference Between CNC Cutting and Other CNC Machining Methods?

There are some differences between CNC cutting and CNC turning, CNC milling, and CNC drilling in terms of working principle, working steps, application range, etc.

Working Principle

CNC cutting cuts the workpiece by controlling the movement and energy input of the cutting tool. Common CNC cutting methods include laser cutting, plasma cutting, and waterjet cutting. The principle is to focus energy (laser beam, plasma arc, or high-pressure water flow) on the workpiece to make the material cut by heat or impact.

CNC turning removes material from a workpiece by controlling the relative motion of the lathe tool and the workpiece. CNC turning is mainly to move the tool on the rotating workpiece to realize the cutting process. By selecting the appropriate tool shape and cutting parameters, the desired shape and size can be obtained.

CNC milling removes material from the surface of the workpiece by controlling the relative movement of the cutter of the milling machine and the workpiece. CNC milling uses a rotating tool to cut on the workpiece, which can be moved in different directions to achieve the machining of shapes such as flat surfaces, contours and grooves.

CNC drilling performs drilling operations on the workpiece by controlling the axial movement of the drill bit of the drilling machine on the workpiece. CNC drilling is mainly the process of using the rotating drill bit to generate axial movement on the workpiece to realize the drilling process.

Work steps

The working steps of CNC cutting include determining the cutting path, selecting appropriate cutting tools and cutting parameters, programming and inputting cutting instructions, and starting the CNC equipment for cutting operations.

And for cnc turning,working steps of CNC turning include selecting the appropriate tool, fixing the workpiece and installing the tool, programming and inputting the turning command, and starting the CNC equipment for turning operation.

The working steps of CNC milling include selecting a suitable milling cutter, fixing the workpiece and installing the milling cutter, programming and inputting milling instructions, and starting the CNC equipment for milling operations.

And what about CNC drilling?The working steps of CNC drilling include selecting a suitable drill, fixing the workpiece and installing the drill, programming and inputting drilling instructions, and starting the CNC equipment for drilling operations.

Scope of Application

CNC cutting is widely used in metal processing, sheet metal processing, construction, automobile manufacturing, aerospace and other fields. Different cutting methods are suitable for different types of materials and processing requirements.

CNC turning is more suitable for machining rotationally symmetrical parts, such as shafts, bushings, threads, etc. Common applications include automotive parts, aerospace parts, mechanical parts, and more.

While CNC milling has advantages for machining parts with complex shapes such as planes, contours and grooves. Widely used in mold manufacturing, aerospace, automobile manufacturing, electronic equipment and other industries.

Just like its name, CNC drilling is suitable for creating holes in workpieces, including circular holes and threaded holes. Common application areas include machining, automobile manufacturing, shipbuilding, construction, etc.


There are different differences in these CNC machining methods. Of course, they also play an important role in different fields. It is precisely because of these processing methods that our industry will develop more rapidly.
