Effect of Heat Generated on Cutting Tool and Workpiece1 Effect of heat generated on cutting toolHigh hardness and heat resistance are major considerations for thechoice of cutting tool depending on the type of materials underconsideration However heat generated duringmachining results in tool wear eventually leading to high surfaceroughness of workpiece reported that the use of cutting fluidduring machining greatly increased tool lifecompared to tool life obtained when cutting fluid was not appliedunder same machining parameters This was so because hardness valuewas preserved over a longer period of timeduring wet machining hence temperature reduction at cutting zoneresulted in a preservation of tool and elongation of tool lifeThermal cracking which is due to the expansion and cracking causedby thermal stresses isanother way the cutting tool    See Answer
