Abstract
A method for digitizing drilling jigs comprising: insertion in a jig hole of a feeler pin provided with a rounded-shaped head having the same diameter as the hole, such feeler pin being connected to a measuring system suitable for finding its position continuously. The method includes storing of the coordinates of a point on the hole axis nearby the surface of the jig; deep insertion of the feeler pin and finding of the coordinates of a second point on the hole axis nearby the back; and calculation of the axis inclination through the coordinates of the two points found.
Claims2
A method for locating a tool positioning point on the axis of a jig hole in a jig having a front surface and a back surface, for use in digitizing drilling jigs, the hole having a known diameter and the method comprising:
- inserting a feeler pin provided with a rounded head having the same diameter as the hole, into the jig hole;
- providing a measuring system suitable for continously finding a position of the head in the hole and on the hole axis;
- storing coordinates of the location of the head at a first point in the hole and on the hole axis, near a front surface of the jig;
- inserting the feeler pin and head deeper into the hole;
- storing coordinates of a second location of the head at a second point in the hole and on the hole axis near a back surface of the jig;
- calculating an inclination of the jig hole axis using the coordinates of the first and second points;
- and
- calculating a third point on the hole axis which is external of the hole and at a distance which is greater than a distance between the front surface of the jig and a maximum depth reached by the head in the hole, said third point being used as the tool positioning point along the axis of the hole.
