But most such tools often overlook a critical material parameter; i.e., the surface roughness of the conductor.
Before tribo-tests, the PI composites were polished using SiC sandpaper with different grain size, 5 pm (R1), 10 [micro]m (R2), 15 [micro]m (R3), respectively, while the surface roughness of GCrl5 steel pin was polished by metallographic sandpaper to a roughness below 0.1 pm.
However, it increases the surface roughness of the machined surface.
* Skidless styli intended for measuring roughness and waviness on sealing faces
The parameters such as incidence angle, wavelength and frequency of SAR data, and field surface roughness is used.
In this test, a wide range of roughness parameters relating to all fields were evaluated, including all kinds of profile parameters, roughness parameters and waviness parameters.
Figure 3 shows the evaporated patterns of the PTFE droplets deposited on smooth and rough substrates with different roughness. The pattern deposited on smooth glass clearly exhibits the widest coffee-ring.
The conclusion of their work was that the main factors affecting the flank wear and the produced surface roughness are the feed rate, nose radius, and approach angle, while the cutting speed had the major effect on flank wear.
There is a very effective method to arrange roughness on the wall.
