| Summary: | Soda lime glass has application in DNA arrays and lab on chip manufacturing.
Although investigation revealed that machining of such brittle material is possible using ductile
mode under controlled cutting parameters and tool geometry, it remains a challenging task.
Furthermore, ability of ductile machining is usually assed through machined surface texture
examination. Soda lime glass is a strain rate and temperature sensitive material. Hence,
influence on attainment of ductile surface due to adiabatic heat generated during high speed
end milling using uncoated tungsten carbide tool is investigated in this research. Experimental
runs were designed using central composite design (CCD), taking spindle speed, feed rate and
depth of cut as input variable and tool-chip contact point temperature (Ttc) and the surface
roughness (Rt) as responses. Along with machined surface texture, Rt and chip morphology was
examined to assess machinability of soda lime glass. The relation between Ttc and chip
morphology was examined. Investigation showed that around glass transition temperature (Tg)
ductile chip produced and subsequently clean and ductile final machined surface produced. |
