-===== Tribological data =====
+The tribological data (coefficients of friction) of the material are entered in the ‘Tribology’ tab. The input is optional and is only required for the calculation of [[en:berechnungen:nutbuchsenberechnung|Grooved bushings]].
+  * **Barrel friction coefficient** $\mu_z$: Coefficient of friction between the plastic and the barrel
+  * **Screw friction coefficient** $\mu_s$: Coefficient of friction between the plastic and the screw
+  * **Friction coefficient at melt film formation** $\mu_{z1}$: Coefficient of friction when changing from solid friction to melt film friction (only required for [[en:berechnungen:nutbuchsenberechnung|limited speed orientated grooved bushing calculation]]). This value is difficult to determine. Calibration based on known grooved bushing processes is recommended.
+  * **Internal coefficient of friction** $\mu_i$: Coefficient of friction between the granules
-Tribological data is required for the consideration of the solid conveying in the feed

-section. These are the values of barrel friction $μ_z$ and the screw friction $μ_s$.

+However, determining the necessary friction coefficients is problematic and error-prone.
-Obtaining the necessary coefficients of friction constitutes a problem. It is
-recommended that users establish the necessary data by conducting test series on
-their own.
