Single point cutting is suitable for the processing category as a manufacturing process.
It includes removing metal from the workpiece using a cutting tool with only one main cutting edge.
A typical example is to open the surface on a vertical boring machine, drill holes internally on a horizontal boring machine, or use standard tools and equipment for fixed-point cutting, this is a good selection of items such as small batch production and 1 pass.
The machine is flexible and can be used to produce a large number of components without the need for dedicated tools.
The cost of basic setup is relatively low.
By managing the feed rate, cutting depth, cutting angle and the type of tool used, high quality components can be produced.
The skills and experience of machine operators are also an important factor, although CNC machining has been adopted for almost all types of single-point cutting recently, which greatly improves the skill required for machine setup and programming than machine operation.
This means that once the equipment is installed and running, the manufacturer can employ less skilled labor to run the machine.
Most metals and polymers can be processed using single point cutting or some ceramics can be processed.
Cutting forms most material waste materials, which are often difficult to recover, mainly due to contamination of lubricants and some changes in the microstructure caused by the processing process using shear action for material removal.
As you can imagine, this will generate a lot of stress and strain at the tip.
Hardened or tempered materials can slow down the cycle time, and tool wear needs to be taken into account if processed at a high process rate to remove the material.
A basic requirement for a single point cutting tool is that it is more difficult than the material being cut, but even in this case there will be tool wear.
The result of this is the need to re-sharp the cutting edge frequently, and the tool may need to be replaced in the end.
Another factor to consider when using a single point cutting tool is the generation of thermal energy;
It is mainly because a cut occurred when the material was removed.
A large part of this heat is used with the resulting material chip, but there will still be a residual amount left on the parent material.
This is why the coolant is widely used during single point cutting.
They also generally provide secondary benefits as cutting lubricants.
What is the best characteristic of single point cutting tool sharpness, even at high temperature, chemical inertia will not wear out. These properties have traditionally been discovered by the use of carbon and low alloy steel, although they do have a tendency to wear too easily.
It is relatively easy to offset this problem to a certain extent, but there is obviously a need to further develop tools with better performance.
High speed steel provides a preliminary solution to the wear problem, which is mainly due to the presence of high temperature during processing, which will adversely affect low alloy steel.
High speed steel is still considered an affordable and effective option for cutting most materials, but a carbide blade has been adopted recently.
The carbide tip, which is used with the tool holder, is usually provided in a triangular geometry and can now be rotated in the holder to provide new cutting tip fixing screws and fixtures.
The early design used brazing to fix the carbide tip in the bracket, and for obvious reasons it was impractical to continue using the tip after wear.
A further improvement in wear resistance comes in the form of a ceramic coating that can be used for high-speed steel and hard alloy tools.
Diamond is another cutting tool material, and although it is the most difficult material to obtain known, it is almost limited to low temperature applications.
The principle of a multi-point cutting tool is roughly the same as that of a single point cutting tool, but has a distinct distinction between multiple major cutting edges.
They are used to remove materials from metals, polymers, and some ceramics and composites.

In other words, they are set up and programmed on a job based on work, and can be quickly changed to accommodate production requirements for small batches or individual components, such as prototype work.
As a support CNC program needs to be written, it is not absolutely ideal to make 1 article.
An exception to this statement is that once the prototype is produced and verified to be suitable for use, the programming code can be used for further mass production.
Therefore, for high single component machining requirements, standard milling machines with digital readings may be a better choice.
Of course, the CNC machine can also be used for mass production, but the machine will be bundled for a long time, which effectively reduces the flexibility.
Broaching is a slightly professional process, for example, when producing key features in the holes of the tube, it is difficult to do with standard machining practices.
The video below shows the level of adaptability of CNC machines and how to use them to produce 3D components.
