1. Thesis:
- Thesis ID:
- Thesis title:

22223DT346 ...............................
Fabrication of damping models using magnetic fluids (ferrofluids)Application for turning tool. ......................................................................

2. Initial data, documents, and sources:
- Data on damping technology.
- Parameters about turning tool holder: S20R-MTJNR16, .
- Parameters of cutting mode when turning.
3. The main content of the thesis:
- Research and design a model to reduce the damper damping of the creeping fluid for
turning tool.
- Design and manufacture jigs for testing during turning.
- Using ANSYS software to conduct stress and displacement simulation of the model
mounted on the table.
-Design and manufacture 25 console beams to experiment for the vibration measurement
process and to the best console to conduct turning experiment with creeping fluids.
- Measure vibrations from the following cases: original shank, shank with hole without
console, shank with console in 3 air environments, oil and water and the console handle
in a ferrofluid environment under the influence of a
...

...
the use of
ferrofluid in turning tool when turning to reduce vibrations under the effect of vibration
frequency during machining with low standards, easy to do and easy to use.
In the end, the process of implementing the project has achieved the following specific
products:
- An application model is given for turning tool in terms of vibration damping when
turning when using ferrofluid.
- Accurate measurements of velocity, acceleration, and displacement values of
ferrofluid and original turning tool shanks.
- Workpieces have lower roughness values than the original turning tool and
determine certain magnet spacing and ferrofluid concentrations.
6.2 Further research direction.
- Optimized damping pattern.
- Study the tool direction and cutting trajectory to achieve the best surface finish.
- Study of damping on other materials (Aluminium, ...)
- Learn more about the damper technology of the turning tool.
