Abstract
Official abstract text for this publication.
A method of machining a workpiece is provided that is capable of forming a fresh air inlet in an arbitrary position in an outer shell of a container. According to the present invention, a method of machining a workpiece is provided that includes: machining to form a round hole in a workpiece using a boring drill having a tubular end portion, the end portion provided with a flat surface and a notch, and having a blade on a side of the notch, by pressing the flat surface against the workpiece while rotating the drill to contact the blade with the workpiece.
First claim
Opening claim text (preview).
1 . A method of machining a workpiece, comprising: machining to form a round hole in a workpiece using a boring drill having a tubular end portion, the end portion provided with a flat surface and a notch, and having a blade on a side of the notch, by pressing the flat surface against the workpiece while rotating the drill to contact the blade with the workpiece. 2 . The method of claim 1 , wherein the workpiece is a delaminatable container including an outer shell and an inner bag, the inner bag delaminating from the outer shell to be shrunk along with a decrease in the contents, and the machining includes forming a fresh air inlet in the outer shell by pressing the flat surface against the outer shell to contact the blade with the outer shell. 3 . The method of claim 1 , wherein the end portion of the drill has a C-shaped cross section. 4 . The method of claim 1 , wherein the flat surface has a radial width from 0.1 to 0.2 mm. 5 . The method of claim 1 , wherein the end portion has an inner surface provided with a tapered surface widening towards an end. 6 . A boring drill, comprising: a tubular end portion; a flat surface and a notch provided in the end portion; and a blade on a side of the notch.
