Definitions
- the present invention relates to a self-penetrating drilling method and a thrust generating tool for implementing the method.
- the kth cutting edge of the nth blade will be called the cutting edge T (n,).
- Each cutter has a face, hereinafter called the attack face, resting on the rock.
- FIG. 4 shows the leading face ⁇ l, referenced 3bl, the cutting edge, referenced 3b2, the point of contact with the rock, referenced 3b3.
- the relative position of the draft plane ⁇ 2, referenced 32, and of the lateral draft plane ⁇ 3, referenced 33, is also shown relative to the leading face 3bl.
- the draft plane ⁇ 2, 32, is substantially perpendicular to the leading face 3bl and substantially parallel to the plane (Xi, Yi).
- the lateral draft plane ⁇ 3, 33 is substantially perpendicular to the leading face 3bl as well as to the plane (Xi, Yi).
- the notations ⁇ l3, ⁇ l2, ⁇ 23 respectively denote the angles of the dihedrons ( ⁇ l, ⁇ 3),
- FIG. 5 represents a perspective view of the interactions between the cutters and the rock 51, the elements described with reference to the figure 1. They have the same reference numbers.
- PC (n, k) will designate the contact point of the cutting edge T (n, k).
- Figure 7 there is shown graphically, in the case of a tool comprising four blades with two cutting edges, the development of the cutting structure along the axis of penetration (z axis) and the order of passage 61 of the cutting edges .
- the lateral inclination ⁇ cin of the cutting front is chosen at the advancing step ⁇ cin. It is specified that when the tool drills along its axis at the advancement step per revolution ⁇ cin, the grooves dug by the cutting edges of each blade during the same revolution are aligned along a line inclined to ⁇ cin relative to the horizontal plane as shown in figure 6.
- the lateral inclination ⁇ cin of the cutting front is greater than or equal to 50 °.
