Effect of wet and dry cutting conditions on dimensional accuracy in turning operation

Abstract EN

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 condition.
