ACTUAL PROCESS PARAMETER DETERMINATION FOR MICRO-ENGRAVING OF FULLERENE FILM
Mechanical engineers are consistently challenged with the requirements posed by contemporary materials machining by using the existing equipment. In this case determining the cutting conditions becomes an actual problem. This paper offers a response to that request in the form of micro-machining of thin fullerene film deposited on a glass plate by using chemical vapor deposition method. Experimental verification of thin fullerene film machinability is conducted on computer numerical control engraving machine using a diamond scraper. Different values of process parameters are combined to determine adequate parameters set from groove edge quality aspect. During machining we noticed intensive wear, so one part of our research was directed towards determining the cause of tool wear. Modern equipment was used for qualitative analysis and near-optimal cutting condition selection and for analysis of wear debris. The results present a basis for further process optimization of thin fullerene film micro-engraving and for introduction of cutting conditions in the existing table for well-known materials.
