A burr creates problem while aligning components in assembly stage and may be harmful to an operator. So, any machining operation needs control of this type of unwanted projection. As an additional deburring process is often required to remove burr, it is likely to increase production time and cost. The aim of this work is to investigate influence of different parameters on burr formation on aluminium block during slot milling. A condition would be recommended at which quite less, or no burr, occurs. Two sets of experiments are done in this work. Experiment set I is carried out at varying tool exit angles, while experiment set II is performed under varying feed. It is observed from experiment set I that at 60° and 90° tool exit angle, burr height is a bit small. When feed is 0.12 mm/ tooth at experiment set II, no burr is observed.

Abstract


A burr creates problem while aligning components in assembly stage and may be harmful to an operator. So, any machining operation needs control of this type of unwanted projection. As an additional deburring process is often required to remove burr, it is likely to increase production time and cost. The aim of this work is to investigate influence of different parameters on burr formation on aluminium block during slot milling. A condition would be recommended at which quite less, or no burr, occurs. Two sets of experiments are done in this work. Experiment set I is carried out at varying tool exit angles, while experiment set II is performed under varying feed. It is observed from experiment set I that at 60° and 90° tool exit angle, burr height is a bit small. When feed is 0.12 mm/ tooth at experiment set II, no burr is observed.
