In this study, machinability experiments on hardened
AISI H10A hot work tool steel with CBN inserts were performed
in dry and minimum quantity lubrication (MQL) conditions.
Hard turning experiments were conducted according to Taguchi
L9 orthogonal array. The effects of cutting parameters (cutting
speed, feed rate and depth of cut) and cutting conditions on
surface roughness were analysed. The analysis of variance
(ANOVA) in 95% confidence level was applied in order to effects
of cutting parameters surface roughness. It was observed that
average surface roughness (Ra) increased with increasing feed
rate and depth of cut in dry cutting condition with CBN inserts. In
dry and MQL cutting conditions, the most important parameter
on surface roughness were determined as depth of cut with
51.79% PCR and 69.68% PCR, respectively.
