Figure  1.  (a)  Polytetrafluoroethylene  (PTFE)  disk  after  the  preparation  cuts  installed  on  the  dynamometer
Table 1. Machined material thicknesses and physical properties. Moisture content before machining was determined by the gravimetric method; the density of the machined samples was determined after equilibration at 20 ◦ C and 65% relative humidity (RH).
