Abstract:
With the growth of manufacturing companies worldwide the utilization of
machining processes become one of the most important operations. The wastes
which are generated from the machining process usually are recycled or
collected for disposal by a legal contractor. The Material Removal Rate (MRR) is
a method used to calculate the waste generated for a particular machining
operation. This data can be used to estimate the budget required to dispose the
solid waste at the beginning of a business fiscal year. This research will focuses
on the proximity of the theoretical MRR value with the physical value of waste
generated during a machine operation. Hence the variance between the
theoretical and practical value are homogenies for all the cutting operation.
Three types of material have been chosen to the current research, there are
mild steel, brass and aluminum. Turning operation will performed for a depth of
cut 1mm, 1.5mm and 2mm depth of cut for each material and the volume of
waste generated will be recorded. A statistical analysis will be conducted to
gauge the homogeneity of variance using the ANOVA. The statistical result
shows that there is no evidence to reject the null hypothesis since all the data
satisfy the assumption of ANOVA. The variances occur due to causes that been
determined in fishbone diagram.
