Hi,
I've been tasked with designing an inspection gage to check the attached part. The gage needs to check the locations of the 4 tips
within a true position tolerance of 0.35mm and no MMC in the feature control frame is given on our customers drawing. This part fits into 1mm sized PCB holes...
Hi,
i have a question regarding fits for plastic gear shafts within a plastic housing. Are there standards for fitting a plastic gear shaft into a plastic slot.
we are making a gear box with plastic gears inside of it. The tolerances of the slots which the gear shaft fits into have tolerances...
Hi,
I have a question on profile tolerances called out bilaterally. please see attached sketch. the profile callout is pointing to a line that is 0.10 inside the actual profile. my interpretation of this is that the tolerance zone is established centered on the 0.10 offset. is this correct or...
Hi,
I need some help. I'm trying to run a true position tolerance analysis using the Monte Carlo method. I have googled it and haven't found much help. can anyone recommend or have some useful information on how to do one of these simulations using excel?
Hi,
I'm working on a project where I want to control the true position of a rectangular feature within a diameter tolerance zone to 3 datum's. My problem is that we want to check this new part with a Gage with round holes in it, and so the tolerance zone we will be inspecting will not be...
Hi,
See the attached example. I want to use true position to control symmetry of the 13.34 to Datum C (the 19.94 dimension), but I want the inspector to square up the part using datums B and C to measure that. would this be the correct way to call it out on the drawing? does this make sense...
hi,
if I use an all around symbol on a profile callout, and I call it out in a detail view; does that profile tolerance apply only in that detail view?
thanks,
Hi,
If I call out the true position of a rectangular slot in only in the x direction, does that apply in the Y direction as well or only in the X direction?
thanks
Hi,
was wondering if anyone has a good method of checking if a complicated mold drawing has all the required dimensions to make the part. especially if profile dimensions are applied to some features.
is it better to model an injection molded part with equal wall thicknesses and equal draft and then round off the width numbers on the drawing. or would you dimension the theoretical sharp corners of the molded part? How does everyone model a molded part?
thanks
