Confirming Perpendicularity of Primary, Secondary & Tertiary Datums

Start date Dec 11, 2011

AI Thread Summary

Primary, secondary, and tertiary datums must be perpendicular to each other when specified with a perpendicular tolerance on technical drawings. If the print indicates this requirement, the part must conform to it to ensure proper fit and function. However, confirming perpendicularity can be challenging when dealing with a point in space. The discussion highlights the importance of adhering to specified tolerances in engineering and manufacturing processes. Understanding these requirements is crucial for maintaining quality and precision in part production.

Do the primary , secondary and tertiary datums need to be perpendicular to each other always ( when specified).

if the datum is speced with perpendicular tolerance then they got to be. If its on the print..part must conform to it. The exception being a POINT in space..how do you confirm that it is perpendicular??

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
