Abstract
Objective: The objective of this study is to investigate the experimental results of roundness error of machined holes using deep hole drilling process. The machining parameters include feed rate (f), spindle speed (s), depth of hole (d) and Minimum Quantity Lubrication MQL, (m). The work piece and tool material used in this study are Cold Mold Steel 718 and High Speed Steel, HSS (5mm diameter) with twist drill bit respectively. After that, to evaluate the quality of holes the roundness error has been used as machining performance. Method: A systematic approached based on Design of Experiment (DoE) was executed using Full Factorial design with added center point. Finding: Analysis of variance (ANOVA) was applied to the results to check the significance of the model. From the ANOVA analysis indicate that the model is significant for a confidence level of 0.05 or 95%.
