Hi, I am designing a bolted joint and I'd like to bounce a couple material selection and manufacturing questions off the knowledgable folks here. Imagine I have a 50" stud with 3" of 1.75"-8 thread on each end. Due to geometry and space constraints the clamped member is not as stiff as I would...

Can anyone point me to a good resource for calculating cutting force on a tool insert? Even a plot or measurement would be a good starting point.

Hi, I have two steel beams that will be joined in a T-shaped geometry. I have completed the load analysis, but I have little experience is in the appropriate method for joining of these memebers. I have a fairly good reference text for designing a bolted connection, but I am largly ignorant...

Hello, I have an old machine that employs a guide pin machined from 8620 steel that is case hardened to 50-60 Hrc that has been galling against a sleeve of 4140 hardened to 35-40 hrc. This is a recent occurance, and my research indicates that the carburizing process used to harden the shell may...

Hello, I need to plug a hole in a high pressure (15000 psi) hydraulic assembly. I have the freedom to drill or thread the hole to any desired size over 1.375". I have tried to locate an OEM cone and thread style plug with no luck for this size range. Any suggestions for vendors or alternate...

Hello, I apologize if this has been covered but I can not seem to find a solution. I am fairly new to Labview, and I am having difficultly getting my application to work properly. I need to output some cutom waveforms from a DAQ card for some motor testing. I have been trying to create a vi...

I need advice on selecting a material that will not experience corrosion from sulfuric acid. All concentrations with working temperatures of -100 to 200 degrees F will be experienced. If velocity of the fluid is an issue, assume 300 mm/s. Thanks!

Hello, I purchased a sheet of aluminum from McMaster Carr with a #8 mirror finish. I can not seem to find an information that relates this surface roughness. Anyone know? thanks.

Hello, I have designed my first gear/pinion set for a rotary table. I have a large 350 mm pitch diameter 0.4 Mod ring gear and and an 88 tooth antibacklash pinion will be driving it. My question concerns alignment. I am designing a mounting assembly and would like to know what type of tolerance...
