I show how to calculate a "fit" using the tables in Machinery's Handbook.

For anyone wondering, Table 8a is on page 653 of the 31st edition of machinery's handbook. Great video! Thanks for providing such good explanations.

Thanks for the videos professor, you have no idea of how useful they are. Question: Do we always start by picking the shaft and then calculating?

New question: Are there tables or online tools for mixed materials? For example, a steel cased bearing in a 6061-T6 hole? Or a steel 1045 shaft with a A36 component (hole)? I realize the steel differences in expansion rate are less than for various steels vs steel / aluminum, but surely there is a tool to allow you to pick the materials, the nominal size, the one that is easier to machine to tolerance, or is fixed in size (e.g. bearing), and return close values for what should work for various types of fits.

@0:24 Professor I think *Allowance* is defined as *smallest hole* to *largest shaft* not *smallest shaft* . Also looks like a mistake at @11:00 subtraction it should be 1.4984. Your tutorials videos are much appreciated. Thanks a million!

Is an H7 hole in imperial the same as an H7 hole in metric? Edit: Also is an RC3 hole the same in metric and imperial? Is that a term used in both?

i m trying to design an upright in which we press fit the bearing ( ID = 25 , OD =47) , to calculate the tolerance i need to give for the design of the upright , can we use this method?
@xluciferzgamingx27492 жыл бұрын
a question, is the diagrams actually shows the tolerance range or visual representation of the diameter and shaft it self?
@LalithS-bg2em2 ай бұрын
Sir, for solving the maximum shaft 1.5000-0.0016 = 1.4984. But you wrote 1.484.

What should I use for parts designed in millimeters to be produced by people used to fractional inches? Should I translate the metric sizes and specify the ANSI tolerance/fit names? I am supplying solidworks files for CAM, but don't want to confuse machinists.

Hi, I would calculate the fits with ASME B4.2 (Metric Fits) and then convert them to decimal inches for the drawing. It is not advised by ASME to put the type of fit on the drawing. Only the dimensions and tolerances are necessary on the drawing.

I am purchasing a pin that already has a specified tolerance from the manufacturer. I need to manufacture a hole that will achieve an FN1 fit with that pin. How do I go about using the tables when I only need to find the tolerance for the hole and not the shaft?
@jeremiahmoeller60472 жыл бұрын
Hi, can you share the basic size and tolerance for the pin? I can make a video where I explain the calculation for the FN1 fit.

At 11:00 you substract the LMC of the hole and of the shaft, the result is 2.7 but it is supposed to be 2.6 ? Am i making a mistake ?
@jeremieohana5057 Жыл бұрын
No, Jeremie, the mistake is on the whiteboard - an arithmetic error in subtraction. The bottom right-hand figure should read 1.4984, and not 1.484.
