In last example slot for 1st part is 24+/-2 For 2nd part dim is 20+/-3 So, If 2nd part is produced at dim 23. Then interference will happen. Suppose we need clearance fit, 1) should we adjust our tolerance to 20+/-2 OR 2) Should we change slot width as 24+/-1 Please let me know 1st option or 2nd option is correct. Or else please correct me if my thought process is wrong Sir. Thank you

Hello Sir, sorry to say but maybe I have confusion I have gone through your video wherein you said that VC for shat is the worst condition as it is the biggest size of the shaft but as I know biggest dia of the shaft is not the worst scenario if dia of shaft is larger then you can reduce it to required size as there is a material available for machining. The worst situation will occur if the shaft is manufactured at LMC, as there is no material is available for machining further.so instead of saying the VC is the worst situation for the shaft, I would say it is a good scenario for the shaft. might be I am wrong, It would be great if you clear this doubt. have a good day to you, sir.

Tolerance stackup is done for assemblies. And worst case for assembly will be shaft bigger and hole smaller. Tolerance stackup is study when u dimensioned the component and completed the design, it will check if there will be any issue during assembly even all component with in their tolerance zone.

Why Chain dimensioning not provided with a close loop? Why the dim 10+-0.5 is not useful in determining the thickness? For vertical gap: 6+-3 i.e gap is between 9 to 3mm and horizontal gap: 3+-3, i.e gap is between 6 to 0mm. In the last example with GTol. it shows interference of 1mm, how to avoid the interference in such case?
@TheEssenceofknowledge

Hi Parag, any dimension system that give more tolerance deposit to a important feature should not be used. From start of loop to close loop, what ever dimension given in drawing must be used, using excess dimension will result wrong analysis. Yes correct, you can check last video in stack up series for solution and another example to solve. If any interference, it can be eliminated by making more precise dimension or best is to change any dimension if we are in design phase. let me know if this clarifies.

Dear Sir, Great video. More information in a sharp manner. God bless you for sharing the knowledge. Have a doubt, in How GTOL affects the Stack up Analysis - normally in GD&T, Virtual Condition and Resultant condition are used in FOS (Shaft, Hole, slot) & not in planner surfaces. Since its for Stackup do we use VC & RC here?
@TheEssenceofknowledge
3 жыл бұрын
We calculate VC and RC case to case.. it depend on the Gtol and how it is used. VC is most important aspect. We need min hole equal to VC of the shaft. And VC is MMC + Gtol for shaft and same for shaft. Let me know if this helps..
@tomaszz4807
3 жыл бұрын
Very useful video for beginners like me. But I do not understand the example at the end. I understand how GTOL can enlarge outer boundary for block/shaft at MMC, and that represents VC - that's ok with me. But Sir, how GTOL can reduce the size of block/shaft at LMC (that is how you explain RC)? It will never happen if we produce part with respect to drawing requirements. Parallelism tolerance 1mm do not allow us to produce part 17mm if we have dimension tolerance 20+/-2 In your example max gap would be 26-17+9. But that is not the truth, as I understand
@TheEssenceofknowledge
3 жыл бұрын
It is a RC and VC both virtual boundary only. At any cross section size tolerance must be followed. Suppose the saft, vc condition is what is worst case hole diameter needed to accommodate when it is at MMC and dislocated by Gtol. Hole size required will be MMC shaft +Gtol to accommodate it any scanario. Parallelism can affect boundary if applied to feature of size otherwise it do not controls location.
