UNDERSTANDING TEMPERATURE EFFECTS ON FRICTION AT TOOL – CFRP WORKPIECE INTERFACE USING OPEN-LOOP FRICTION TESTING

Cutting processes of carbon fibre reinforced polymer (CFRP) material generate significant energy in the form heat which can be detrimental to final surface and sub-surface quality. By artificially changing temperature workpiece simulate cutting temperatures, thermal effects on friction metrics understood. Feed rate CFRP pre-heating for macro nanoscale open loop pin plate testing has been completed two aerospace grade materials with steel, carbide coated pins give an insight fundamental tool wear that occurs machining.
