    Datum reference frame of three-bearing arrangement shaft

    Hi all, just a general question how to proceed if we have to inspect long shaft, which is supported not on two, but three (or more) bearings. When the shaft is supported on two bearings the standard practice is to use the corresponding bearing journals as datums and measure runout with regards...

    Inspection of keyway in bore

    Hello, Does anyone know how symmetry control of internal keyway can be performed with portable measuring device, and if there is such device at all in existence. I am not interested in the measurement of the width of the keyway, but rather its position with respect to the bore axis, so that...

    GD&T with general tolerances between datums

    Hi all, I am trying to compose tolerance callout for the part attached. The idea is that overall dimension can vary more than position of holes relative to datums B and C, and I wonder how to properly annotate it. I am wondering should dimension 1600+-3 be basic? Should I use composite callout...

    Measuring runout on a shaft relative to two datum surfaces

    Hi everyone, I am struggling with one practical issue how to measure shaft runout, when two datums are specified simultaneously, having different diameter size. Can this be achieved only on a lathe with dial indicator? Is it possible to align both diameters this way, without using custom made...

    GD&T of extruded part with irregular profile

    Hello, I don't have experience with GD&T, but I wanted to use it on a particular part. I read some materials on the fundamentals of GD&T, but unfortunately all examples were fairly simple parts with straight prismatic surfaces. My part has fairly irregular profile, meaning it has no straight...

    Part Numbering In Detailed Assembly Drawing

    Hello everyone, I need some assistance in the highly discussed topic of part numbering. We have order which is mainly structural - plates, U-beams, etc. We get the drawings in pdf format from our client. They have pretty good numbering system, which goes like this: xxxx-yyy-zzz-rev.00. xxxx is...

    Display 3d Sketches in Multiple Drawing Views

    Hi, I need help to solve this problem. I'm trying to create a drawing for a boiler wall panel. Basically it's an assembly from 23 tubes created by sweeping two circles along 3d sketch. For the drawing I want to represent each tube as a single line, not as a solid model for simplicity and better...

    End Cap Pressure Simulation

    Hi all, I'm new to the forum and SW Simulation so please help me on this. In our company we use very often custom made end caps for hydrotest purposes of boiler equipment. I've attached a cross section for the most common type we use. We have to calculate the thicknesses of these end caps so...
