The influence of tool kinematics on surface texture, productivity, power and torque of normal honing
Abstract
Purpose
In this paper, the influence of cutting regimes on surface texture and productivity of cylinder liner is shown, obtained by normal honing. Furthermore, normal honing power and torque is discussed. The paper aims to discuss these issues.
Design/methodology/approach
Normal honing was done on grey cast iron cylinder liners. Both pre- and finishing honing were done by mechanical means, to achieve the required level of surface texture quality, traditionally achieved by a combination of electrochemical pre-honing and mechanical finishing honing. To determine the most influential parameter on normal honing, statistical mathematical model was devised. Surface texture was controlled by light microscope and scanning electron microscope.
Findings
Mathematical model describing the influence of cutting speed, feed rate and depth of cut has shown that the most influential parameter on maximum peak height, productivity and specific volume productivity was shown. The most influential parameter has shown to be cutting speed.
Practical implications
There are two practical implications of this work: this work is a further contribution of understanding normal honing and the influence of various parameters on the quality of normal honing, both in view of surface texture and productivity, as the main drawback of this method. This work offers useful information for honing system designers, as torque and power of normal honing are given.
Originality/value
Two main achievements are given in this paper: as the main drawback of normal honing is lower productivity, the optimization of honing parameters may to some extent resolve this problem. Lower productivity is the result of lower cutting speeds and pressures, which in turn, give normal honed surface a higher quality compared to plateau honing. Lower power and torque demand a lower energy demands, as well as a less complex honing machine which may lead to further savings.
