Drilling is one of the basic machining process of making holes and that is is essential formanufacturing industry. Therefore optimization of the parameters that control the process ofmicro drilling is unavoidable in order to have the best results. In this study the parametricoptimization of micro drilling has been studied by considering a number of parameters such asspindle speed, feed rate and drilling tool size on material removal rate (MRR), surfaceroughness, dimensional accuracy. In this work, a study has been done on optimum drillingparameter for carbide drilling tool in micro-drilling processes in order to find the best drillingparameter for copper as a work piece material. Micro drilling experiment with 2.3mm to 2.6 mmdrill sizes were performed by changing the spindle speed and feed at three different levels.Comparative analysis has been done between surface roughness, MRR and dimensional accuracyof drilled holes by experimentation. From the result, the surface roughness are mostly influencedby spindle speed and feed rate. As the spindle speed increases, the surface roughness willdecrease. However the surface roughness increases with increase in feed rate. The value ofMRR decrease when the tool diameter, spindle speed and feed rate decreases. As drilling tooldiameter, feed rate and spindle speed increase the dimensional accuracy of drilled hole willdecrease. The increment of spindle speed and feed rate value will affect the tool wear.

Leah Reich is the only child of an ignoble baron of a city nobody cares anything about. Her father’s love has long gone cold in the face of her antics and he threatens to disown her at the age of twelve if she steps out of line one more time. Change is hard though, and Leah eventually does find herself cast out of her home, her family, and her way of life five years later.With the help of a witch whose interests are less than charitable, Leah goes to her country’s academy for guards, a debt incurred and her options limited. In the academy she discovers seeds of an insurrection and is unable to decide whether her own loyalties lie with the class of people she left, or the class of people she now calls friends. She discovers that being a man is not always safer than being a woman, and that trouble sometimes seeks you whether or not you try to hide from it. Leah rediscovers the person her father tried to bury and loses her fear of the future as she learns that success isn’t and never will be found through groomed footpaths and decisions made for her by others.
