... load from zero to a maximum at a deformation speed of 1mm/s and then descends gradually to a minimum load at a speed of 5mm/s for AA2024-O and AA6061-O. Since the load reduction seen, with grease as lubricant, is probably due to thermal softening, it will not be considered a desirable lubricant under...

...) is heated locally by a laser beam, which passes through the diamond tool tip. The workpiece is heated beyond the thermal softening point in order to study the effect of increased temperature. The cutting and thrust forces are reduced when machining is done above the thermal softening temperature...
