Study and Analysis of Cutting Parameters of Rubber Rollers Using Doe Technique

Rubbers include natural rubbers and synthetic rubbers. Natural rubber is a naturally occurring substance
obtained from the exudations of certain tropical plants. Synthetic rubber is artificially derived from
petrochemical products. Among the most important synthetics are styrene-butadiene, polybutadiene, and
isoprene as well as ethylene-propylene rubbers. The prices of these synthetics have been historically in the
range of natural rubber prices and their markets have, although to varying degrees, overlapped those of
natural rubber.
Rubbers have wide applications in automobile, aerospace, electrical and many other manufacturing
industries, but still not much work has been done on its quality characteristics with different input process
parameters. A thorough understanding of the process behaviour is very crucial in order to control the
castings in terms of quality. In this work, the main quality characteristics, namely surface roughness and
hardness were modelled both linear and non linear, with respect to process parameters Speed, Feed and
Depth of cut and analysed using Design of Experiments Methodology with Response Surface Method.
The effects of process parameters were explained with main effect plots and response surface plots. Finally
multi response optimization, using desirability function approach was done on the best fitted models.
