HOW TO DRAW A CAM PROFILE - MECHANICAL DRAUGHTING N4
Переглядів 32 тис.4 роки тому
This video focuses on how to draw a cam profile. The content was based on a question extracted from a past exam paper for Mechanical Draughting N4. Objectives of the presentation By the end of this presentation, viewers would have the knowledge of drawing the displacement diagram for the given performance and to draw the cam profile
Sir how would the internal left hand thread look like in which direction?
@@tryphosamasenya6932 how are you.. You can see that we have drawn a right hand internal thread and we can see the lines representing the threads are sloping down to the left...now for a left the lines will slope in reverse direction of the right hand
What angle did u use to measure that line which form a UAR
what software did you use to draw?
AutoCad
Thank you. It was helpful sir
Isn't on 1:35 to get the diameter [ min diameter (Dm ) ] you have to to subtract outside diameter and wire diameter ?!
Yaah thats correct and the Dm is going to be 58....which is exactly the same as used on the video
thanks
Fast and easy 😊
I needed this , thanks Charles
Daz greatb👍
Thank you bra 🙏 💯 🙌
I am so happpppy with is method of drawing a thread
Sound Voice is too bad
Thanks will imporve on it
thanks Charles
Where's that 16° come from, can you explain that please.
Thanks a lot, keep it up sir.
but u have used anti clockwise ...the question was stating it should be clockwise
When the cam is moving in a clockwise direction...the numbering on the profile must be counterclockwise
He's 100% right.
Thank you
How do you know it 16°
Yeah I don't understand also
Which one are you referring to as 16°
On drawing those lines you are going to draw lines that are incline at 60° not 16°
Which software do you use for drawing?
I use AS SW and AUTOCAD on this vjdeo its AUTOCAD that l used
The theory about triangular threads (metric and whitworth) is very useful, thank you for the knowledge, sir.
