Flat pattern of a cone with its base cut by two planes
A truncated cone whose base is cut by two planes meeting in a valley, like a hopper set astride a ridge. The valley can stand off the axis and the two cuts can have different angles. The top stays a true arc; the base edge is worked out generator by generator, with a press line where the valley meets the cone.
A truncated cone with its base cut by two planes meeting in a valley, which may stand off the axis.
Sizes you enter
- Base diameter (D): At the level of the valley, on the surface chosen under Sheet.
- Top diameter (d): The square top, on the same surface.
- Height (H): From the valley up to the top.
- Valley offset (X): From the axis to the valley, seen from the front: + toward the seam (left), − away from it. 0 = on the axis.
- Left cut angle (β1): The base cut on the seam side (left in the front view), rising from the valley: its angle to the level.
- Right cut angle (β2): The base cut on the far side (right), rising from the valley: its angle to the level.
What you get
The exact flat pattern of the part, worked out for the sheet thickness measured on the inside, the mean or the outside, with numbered press lines, the part in 3D, its weight and cutting length, and a DXF for laser, plasma or waterjet cutting (STEP as well).
