Motion path of the cutting tool in CNC milling and CNC turning

CNC milling and CNC turning both are widely used CNC machines in different industries for vast applications. These machines use different motion paths to remove the material from the workpiece. CNC milling creates holes, slots, threads, and other impressions by its cylindrical rotating cutters that can move along in multiple axes. Most of the CNC milling machines can move into three to five axes to carry out operations. These machines can be assembled horizontally and vertically.

In CNC turning the motion of the cutting tool is decided by several parameters. These parameters are workpiece material, tools material, size, and more depending upon the operations. Generally, the cutting tool moves axially along the workpiece to remove the material and form a particular shape.

Workpiece

The workpiece in CNC milling machines is stationary. This clamped workpiece remains in the same position throughout the process and the rotatory cutting tool moves around it at a different angle to remove the material from the workpiece and get the desired shape.

In CNC turning the workpiece is rotating while the cutting tool keeps its position stationary. It holds the bar in a chuck and rotates it and feeds it to the tool to remove the material from the bar and give it the needed shape.

Machines Used to perform CNC milling operation

There are many machines used for milling operations, but the most used machines for the milling process are a rotary table, planetary milling machines, and drum milling. These all three have different operations such as rotary milling machines employs circular worktables which rotates around the vertical axis. Planetary milling machines have stationary worktables and the workpiece is cylindrical, the rotating tool moves across the workpiece for internal and external features. The drum is the same as the rotary table except for the worktable which is called drum moves around a horizontal axis.

Machines Used to perform CNC turning operation

Same as milling the CNC turning also have different types of machines. These machines offer a wide variety in their operations. Some of these machines are bench lathe, engine lathe, and toolroom lathe machines. The bench lathe machines are general lathe machining used by hobbyist but still requires skillful machinist. The engine lathe machine is the most common type of CNC turning machine used by a variety of industries due to its efficiency, capability, and lower cost. It is used in high-speed CNC machining tasks. The toolroom turning machine is the same as the engine lathe machine but with high-end machining capabilities.

Tool Selection

Tool selection in CNC milling and CNC turning depends upon the nature of production, machine type, size and hardness of the material, and surface quality of the material. Here are some of the tools used by CNC milling and CNC turning.

  • CNC milling

Multi-point: This method uses multi-point cutting tools that can be more than two or even a hundred. This type of cutting tool makes the milling machines more productive and efficient. These multiple cutting tools engage and disengage with the workpiece to remove the material from the material and get the desired shape. These multiple cutting edges improve the feed rate with utmost accuracy.

  • CNC turning

Single-Point: CNC turning uses a single-point cutting tool that remains in constant contact with the workpiece. Heat generation is high because of the single cutting tool and constant contact with the workpiece which sometimes leads to the breaking of the cutting tool. These breakages cause the process to stop until it is replaced which makes this process a little more time taking than CNC milling.
