Abstract
Tool life estimation for the cutting tool before the machining process is important due
to economic and quality consideration. Thus, developing a model that can predict the tool life with
high accuracy is an important issue. This paper deals with developing a new model of tool life for
mixed ceramic tools in turning hardened steel AISI 4340 based on experimental tests. The
experiments were planned and implemented using Central Composites Design (CCD) of Response
Surface Methodology (RSM) with three input factors: cutting speed, feed rate and negative rake
angle. The Face Central Cubic Design has been used as a special case of CCD. The analysis of
variance (ANOVA) has been conducted to analyze the influence of process parameters and their
interaction during machining. The first and second order models have been developed. It was
found that the second order model provide higher accuracy prediction than the first order model.
It was observed that the cutting speed is the most significant factor that influences the tool life for
the two models, followed by the feed rate then the negative rake angle. The predicted values are
confirmed by using validation experiments. Copyright © 2013 Praise Worthy Prize S.r.l. - All
