Thread making

hi,

I have a question about thread making in Solidworks ? first of all , Please tell me any good thread making reference which explain how to consult Machinery Handbook while making thread in Solidworks (video with audio).

2ndly , can some one help me how to make 1 11/16" - 16UN - Class 2B thread in the attached part file (at the helix side). i know trig but my concept about thread design is still missing some thing that i dont understand, why i am not grasping the concept . i avoid thread making feature. I dont know the reason. all suggestion and help appreciated.

Major Dia 42.965

min

42.1.9

Pitch Dia 41.933

41.603

Minor Dia 41.245

Thanks

Asad

one,.. I don't believe you can use a "block" as a profile to sweep?
two... check your units,.. your mm and inch values don't seem right?

I can't open your file but here is an example of that thread modeled. The diameter of Cut-Extrude1 comes from the average of the minor diameter values. The pitch of the helix obviously comes from the thread pitch (1/16). In Sketch9, the construction line length is equal to half the pitch, and then the diameter dimension to that line is the average pitch diameter. Then I just set the thread OD to .005" above the minimum OD value.

By the way, I got my values off of a separate chart that was in inches, so I didn't verify your numbers that you posted.

  Wikipedia is your friend on unified thread definition.
