Abstract
A method of machining a plurality of intersecting bores in an object, the method comprising steps of machining a first bore, plugging the first bore, machining a second bore so as to intersect the first bore, and unplugging the first bore.
Claims15
A method of machining a plurality of intersecting bores in an object, the method comprising steps of:
- a) machining a first bore;
- b) plugging the first bore with a first plugging member;
- c) machining a second bore adjacent the first bore so as to acutely intersect the first bore and the plugging member;
- d) removing the plugging member from the first bore;
- e) plugging the second bore with the first plugging member;
- and
- f) machining a third bore adjacent the second bore so as to acutely intersect the second bore and the first plugging member.
