Abstract:
High production machining, inhcrenlly generates large amount of heat leads to
high culling zone temperature for its higher ~ulting vdocity, feed and depth of cut. Such
hi gil ell Lling \cmp",alllfc if not reduced impairs surface integrity of th.o product arid reduce
dimeMional accuracy as well as tool life. Conventional cutting fluid can not maintain (his
silllutjOl1 properl}'_ Though in lower velocity a smnll amount of [luld enter in to the
llllcrtoce lor its capillary action bllt in higher \'clo~ily it is nol evident. As cutting !luid can
not r~ach into the chip-lOO! and work-tool inlerface due to low pressure and low boiling
temperature, it cannot effectively lubricate and cool the tool and job. Low boiling
temperatme cause vapori7alion of cutting fluid and prevent it to enter into cutting interface
making a harrier to flow, High-pn:ssuTC coolant (HPC) jd is an effective alternative to
reduce temperature anti tool wear. HPC jet applied diagonally to thc in5ert~ cutting edgc
remOves heat and reduce tool wear and also provide better lubrication in the lool tip and
culliL1~int~rf"ce.
Keeping these in view, obje~live of the present work is to m'lk~ an experimental
investigation on the role of high pressure cool ing jet in tuming stainless steeL
