Machinability Evaluation Testing that “Visualizes”
Machining Phenomena
The advanced technology that supports our rich lives is constantly evolving.
Furthermore, in order to survive in an ever-expanding global competition, research and development with an eye to the future is extremely important.
Yamamoto Kinzoku uses its unique measurement and evaluation technology through machinability evaluation testing to deepen technology and build efficient processes,
thereby realizing the “visualization” of machining phenomena and working as a joint research partner to solve your company’s challenges.
I want to know better conditions than the current machining conditions
I want to know the machinability of new tools, new materials, and new cutting fluids
Shortage of staff, machinery, and time for evaluation testing
By conducting quantitative analysis instead of relying on the intuition of experienced personnel for comparison with conventional methods,
it can lead to reliable reduction in machining time, quality improvement, and research and development.
Testing is possible on both NC lathes and machining centers.
We have experience and achievements in testing difficult-to-machine materials (SUS440, SUS630, Ti-6Al-4V, Inconel, Hastelloy, Stellite, etc.).
The measurement and evaluation equipment and testing facilities that can be used can be confirmed here.

Evaluation Criteria for Machinability Evaluation Testing
Tool Wear
The cutting edge of a tool is subjected to high temperature and high load during cutting, and it inevitably wears.
We conduct tests under various conditions and quantify the amount of tool wear.
In addition, component analysis of the worn part can be performed using an SEM (Scanning Electron Microscope).
Cutting Resistance
Cutting resistance is the resistance (force) generated between the cutting tool and the workpiece during machining.
We use a cutting dynamometer manufactured by Kistler to quantify the resistance applied during cutting.
If the value of the cutting resistance is large, it can be judged that the cutting load is large and the sharpness is poor.
Also, if the amplitude of the cutting resistance is large, it indicates unstable cutting and a high risk of imminent tool damage.
Thus, by comparing the magnitude of cutting resistance and its amplitude, it is possible to predict the superiority or inferiority of tool life in a short period.
Temperature Measurement
The thermal energy generated during cutting is significantly related to tool life.
We measure the temperature of the tool and material during cutting using MULTI INTELLIGENCE®, thermography, and thermocouples to evaluate the temperature transition and distribution. MULTI INTELLIGENCE® is a monitoring device capable of real-time monitoring of the tool temperature during cutting. Temperature measurement while applying coolant is also possible (inner-through compatible). It is also possible to measure the temperature of the drill cutting edge, which could not be measured with infrared thermography. (#30, #40, #50 compatible. Custom products require consultation)
Monitoring using infrared thermography is also possible.
Surface Roughness
By using a non-contact surface roughness meter from Zygo, not only can the surface roughness be measured,
but the built-in interferometer also allows for 3D visualization of the surface.
Observation of the machined affected layer using a field-emission scanning electron microscope is also possible.
Chip Shape and Color
By visualizing the chip shape and separability, it is possible to grasp the risks associated with each condition.
It is also possible to check the chip discharge status using a high-speed camera.
