Patent ID: 8251619

Claim:
A hole machining method, comprising: a: determining a minimum number N of holes to be drilled in an area of an object; b: drilling a first hole and a second hole in the area, the first hole and the second hole drilled at opposite ends of the area; c: setting the first hole as a start point and the second hole as an end point; d: in response to the number of holes between the start point and the end point being not less than three, setting a dividing point between the start point and the end point, wherein a number of holes L to be drilled between the start point and the dividing point satisfies: L=2 n +1, where “n” is a maximum natural number which can satisfy 2 n +1≦N; e: determining whether 2 n +1≦N, and going to step g in response to 2 n +1=N; f: drilling a third hole at the dividing point in response to 2 n +1<N; g: drilling the number of holes L between the start point and the dividing point, comprising: g1: drilling a fourth hole at a middle of the area between the start point and the dividing point; g2: setting the first hole at the start point and the fourth hole at the middle of the area between the start point and the dividing point as a new first start point and a new first end point; g3: setting the fourth hole at the middle of the area between the start point and the dividing point, and setting the third hole at the dividing point as a new second start point and a new second end point; g4: drilling a fifth hole at a middle of the area between the new first start points and the new first end point, and drilling a sixth hole at a middle of the area between the new second start points and the new second end point; and g5: repeating the steps g1-g4, until the number of holes L are drilled between the start point and the dividing point; and h: setting the dividing point as a new third start point, and the end point as a new third end point, and returning to the step c.
