Week 14 challenge
Butterfly Valve: Assembly
AIM:- To assemble all the designed parts of the butterfly valve and apply GD&T to the entire assembly using NX.
Assembly:

Steps:
- Imported all the design files in the assembly file.
- Infer Centre/Axis & touch constraints are applied to the hole of the disc plate to the shaft hole and the surface where the disc plate is attached respectively.
- The shaft is aligned to the main body side hole.
- The side surface of the disc plate is applied with the main body internal's surface with touch constraint.
- The axis of the Lever is inferred with the shaft's axis and aligns the key way of the parts.
- The retainer is inferred with the 3 holes on the main body to cover the shaft.
- The nut touches the lever to fix the shaft to the main butterfly valve body.
- Screws are fixed to the holes using infer centre/axis & touch constraints.
- After the assembly is done, GD&T is applied to the connecting parts.
- The holes are given profile tolerance.
- The holes on the other side are given position tolerance with respect to the datum holes.
