Conversion to Drill Machinable Hole Feature segment


SolidCAM determines the following dimensions of the upper and lower Hole Feature segments of the pair. In the scheme below, the segments are represented as two cylinders surrounding the segments.

The scheme of the Drill segment generation is the following:

  • The vertex of the cone is located on the same depth (hr_segm_height) as the lower point of the lower segment of the initial Hole Feature.

  • The diameter of the Cylinder (hr_segm_diameter) is the same as the diameter of the Hole Feature Segment.

  • The resulting Machinable Hole Feature segment is extended upward till the Hole Upper Plane.

  • The Cone angle (hr_segm_angle) is 118°.

 

In some cases, according to the General conversion rules described earlier, the upper segment is absent. In this case the upper segment will be None and the segment Height will be 0.

Exception: In case of translation of a through Cylindrical Hole Feature segment into a Drill Machinable Hole Feature segment, the hr_segm_height parameter of the Drill will be the following:
