Özet:

 

The effects of a number of cutting tool coating materials on  the surface quality of workpieces, depending on various cutting  parameters, were investigated.  AISI 1015 steel was processed without  cooling on a lathe using 4 different cemented carbide cutting tools,  i.e. uncoated, coated with AlTiN and coated with TiAlN using the PVD  technique, and one with 3-layer coatings (outermost being TiN) applied  by the CVD technique.  Among the cutting parameters, the depth of cut  was kept constant (2.5 mm) while the cutting speed and feed rate were  changed.  Five cutting speeds (50, 73, 102, 145, 205 m/min) and 2 feed  rates (0.24 and 0.32 mm/rev) were used during the machining process.   Coating type, feed rate and cutting speed have different effects on  surface roughness.  In the experiments, less average surface roughness  was obtained by using a 3-layer coated tool coated outermost with TiN.  The lessening of cutting speed by about 33% improves the surface  roughness by about 26%, and increasing the cutting speed by about  310% resulted in an improvement of about 69%.
