- Meaning of O-slash in data sheet about gear diameter?
I have this data sheet for a stepper motor: The pitch diameter of the pinion attached to it is listed as "Ø6" What unit is this? Looking at the wikipedia page for Ø it seems like this is just a no
- Lowercase phi (φ) seemingly used for diameter in diagram instead of Ø?
On a technical drawing for resistors, the lead diameter was given as $\\varphi 0 55\\text{mm}$ Since they also specify the wire is 24 SWG, and 24 SWG is a diameter of 0 559mm, did they simply use φ
- mechanical engineering - Understanding hole specifications . . .
4 x means it applies to the four instances that look similar on the drawing Ø 5 means the hole diameter (drill size) is 5mm “Thru all” is added here to remove the requirement for a section view to show hole depth You can’t tell by the outlines whether it’s through, or you can see the bottom of the hole M6x1 0 - 6H is the thread and tolerance to be tapped into the drilled hole
- What does this line with cross means in the blueprint?
The diameter symbol (⌀) (Unicode character U+2300) is similar to the lowercase letter ø, and in some typefaces it even uses the same glyph, although in many others the glyphs are subtly distinguishable (normally, the diameter symbol uses an exact circle and the letter o is somewhat stylized)
- How to interpret general tolerances (e. g. , ISO 2768)
I am quite new to mechanical engineering, but currently working on a project which I eventually want to sent to a CNC service for machining Many services I found can manufacture to, e g , ISO 2768-m
- What is a tolerable amount of elongation in steel?
I was looking at the elongation of various steel alloys, and the numbers were in the 10-20% range Is this the amount of elongation at the point of failure? If so, what is the percentage of elong
- mechanical engineering - AutoCAD circle dimension annotation meanings . . .
What do the following annotations mean in this AutoCAD drawing mean? R1 25 TYP (circle hole Left) 2XØ1 0 (circle hole Right) Ø1 25 (circle hole Bottom) Based on those annotations, what is the diam
