I have been reviewing materials quoted from a variety of suppliers. With my drawing requiring 316L (Free Machining, Annealed 1.5" Bar) I have received certs indicating minimum yield strength of:
25ksi, 29ksi, 36ksi, 40ksi, 42ksi and 45ksi
How can the same 316L material be so different?
Am I...
I have a part which is a thin metal panel having a label applied. Due to source of part being of lower quality than price, label is often misapplied.
I take label.ai file and place on the solid, but this does not show on the drawing. Is this possible? My workaround is to place label.ai on...
I am looking for a recommendation for materials for long-term direct contact with saturated NaCl. While 316 is "compatabile" I am wondering about long (3-5yrs) contact. We could coat or otherwise improve the surface but the costs must be considered. Any suggestions?
Our marketing department has gone to great lengths to educate our clients to the benefits of ceramics...without actual testing. Lo and behold the ceramic parts do not show any actual improvement (other than larger commission dollars to said marketing department.)
Since we have sold this, now we...
I am using the following snippet of code to plot point data from a bit of calculation software. These points are not described by an equation, and because the points are very close together SW will not create a spline through them. Dropping every N points doesn't work as they are not very...
Hello,

Lets say I have a sketch with hole pattern, each pattern mounts one workhead to turret lathe. Now lets say I have second sketch on surface of turret ring with points to locate and rotate pattern to align correctly. I do this for frist one, but then I need to drive the number of points (and...
I am working with a gerotor pump, I have measured the inner and outer rotor profiles but I wonder how to compute theoretical displacement volume to determine change in efficiency due to wear. I try this free software online for design gerotor but it cannot match to my measurements (always error...
Hi all, I order gears and (only) specify:
No. tooth
Dia Pitch
Pressure Angle
Face width
Ball Diameter
Outer Diameter
Diameter over balls
I get pure junk, involute profile is good on 1/2 of tooth, like arc tangent to addendum circle and dedendum circle on other 1/2. Any two even from same lot...
We are making parts for others, this will be used in food service (dispensing.) This piece is AISI 304, but what after processing must be done? We grind/lap to finish size so do we must passivate afterwards? Anything else to do?
What is best way to make external surface only type model?
I tried saving as sldprt part choosing external faces option but this is only surfaces not solid. I have also exported as iges, step, stl, etc. and re-imported to try to make this. Only close with export as stl selecting flatten and...
I am using Ferrotitanit for shafts becuase of much higher stiffness. Now we talk about making the drive gear as part of this instead of shrink this on afterwards. I know normal Ti would be bad for gear becuase of galling, but would the SS addition of this material prevent this possiblity? Mating...
We have a product on the market for many years which has 18GA steel sheet formed for cabinet. Always customer used external 2.4 GHz antenna mounted on top. Now with laptops becoming much cheaper, they start to use laptop with mini-PCI internally and no provision for external antenna.
They ask...
Normally I specify DIN6797 toothed lockwashers when working on structure of machine tools. Recently I have needed countersink screws, so I specify DIN 6798V countersink serrated lockwashers. I see that this 6798 standard also applies to serrated flat lock washers.
I ask what is purpose for...
Customer has asked that we change from clear zinc finish to a satin-finish with uniform grey appearance. This is a welded lever arm that cannot be painted so I search for new process. I like the gloss finish black from salt-nitride or waxed black-oxide myself but customer is always right.

I am working with a PCB assembly that is using unusual fasteners. These are #0 Phillips drive M3x0.5 thread - 5mm thread length but with head flat on both sides not PAN, CHEESE, TRUSS or anything I find, also very low profile. Looks like a 90° flat head but with the 90° gone. Also has blue patch...
I have an older machine cooling system in the shop (not recirc but open to drain). Infeed is 5/8" dia line (~40psig) to T and valve that splits off feed to fill open top reservoir. After T fitting system is all ~3/4" to cooling system (then maybe 2.5" at exit from cooling system to drain.)...
