This work is done by turning a medium carbon steel bare which contains
0.35%C using high speed steel cutting tool. Dimensional deviation is taken as a
criterion to compare between parts produced by dry and wet cutting condition. It is
observed that, in traditional wet cutting condition by water-oil solution, an irregular
conical shape is produced and the diameter of the work piece is increased from initial
to the end of the work piece. But in the dry cutting condition the diameter is near to
the desired diameter because the decrease in the tool length due to a flank wear is
substituted due to the thermal expansion of the cutting tool. Fortunately, it is observed
that the dry cutting condition is more accurate in diameter than the wet cutting
