Task

Model a brass hose barb fitting as a single part and produce a fully dimensioned drawing of it. Work in millimetres. Follow the supplied dimensioned diagrams diagram_01.png and diagram_01_detail01.png.

The part is a turned, axisymmetric body with a hexagonal wrenching flange. It has three zones along a common axis.

Barbed hose spigot

A series of tapered barbs.
Outer barb diameter 12.95 and root diameter 12.02.
Barb crest bands 2 wide.
A 1 x 1 lead-in chamfer at the open end.
A 1.5 step and a plain 3 wide relief or neck section next to the hex.
A 5 long portion between the last barb and the hex face.
An R1 fillet where the spigot meets the hex.

Hex flange

24 across flats.
Chamfered corners as shown.
The hex face to the thread start is 5.92.
An R1 undercut fillet at the thread side.

Male threaded end

10 long.
Thread major diameter 20.96 (1/2" pipe size).
Modelled with visible helical thread form.
A 1 x 1 chamfer on the thread lead.

Overall length is 45.

A through bore runs the full length. At the threaded end it opens into a counterbore of diameter 14.5 and depth 8. Apply the 1 chamfers indicated at the bore mouths.

Create a drawing of the part on an A3 sheet. It shall contain:

A front elevation.
An end view looking along the axis that shows the hex.
A full longitudinal section view.
A shaded isometric view.

Dimension the drawing as shown:

In the front elevation: 45, 10, 5, 5.92, 1.5, 3, 2, 12.95, 12.02 and 20.96.
On the hex in the end view: 24.
In the section view: 14.5, 8, the 1 chamfers and the two R1 radii.

Deliver a Creo part file and a Creo drawing file that references it.
