Hello everyone,
This may not the the right forum but I’m looking for recommendations on a user-friendly drafting program that can handle 3D wireframe modeling, specifically for drawing and rotating models.
Our EDM software can import 2D closed profiles at two different Z elevations to create...
Hello,
I've a cylindrical bearing raceway for nine loose 0.2500" bearing balls that matches 7/32" radius gauge. My question is that whether that is correct and why? Is there a specification for designing such raceways?
Thank you
Pete
Hello,
I have an application where I need to heat a rotating disc to ~100C. The unit is hand held similar to a pizza cutter...
I appreciate any/all ideas

Hello,
in our manufacturing process we use 19mm high by 3mm thick heat treated 1045 steel cutting knifes. These knifes have been harden to 36-38 HRc using bainitic hardening process. Recently we'd received a material batch where one side of the knife measured 35 HRc and the other 28 HRc, but...
Hello,
I have 20+ carriages on a single 3m gantry that require electrical and pneumatic power. I'll be using main PLC to control slave PLC on each carriage using industrial WIFI signal. I can get the power to each carriage using conductor rails (street car idea) but how can I get compressed...
Hello,
I need to find an equivalent steel to ASTM A514 grade B in Europe. Can anyone suggest an online conversion site or does anyone know what could the equivalent be?
Thanks
Pete
Hello,
I'm looking for an equation to calculate force generated by an electric solenoid.
I have an application where I need to generate 80 lb of force on an 3/8" rod that will never come out of the coil and I have no length limitation so the coil can be very long...
Thanks in advance
Pete
Hello,
I have an oscillating steel blade cutting soft plastic at 8000 oscillation/minute and 9 in/minute feed and I wish to calculate the blade temperature. Even simplified calculations would help... How should I go about it?
Thanks

Hello,
I'm looking for an alternative to 'beaver' tool steel made by Atlas Specialty Metals, who went bankrupt about 10 yrs ago.
So far, I have been able to find out its composition:
C 0.68
Mn 1.20
Si 1.00
Cr 8.25
V 1.00
Mo 1.40
Ni 1.50
I appreciate any and all help.

Hello,
could someone tell me the ANSI or ISO designations for these two steel compositions:
C Si Mn P S Cr
0.30 0.25 0.50 0.035 0.040 0.95
C Si Mn P S Cr Ni Pb
0.98 0.23 0.46 0.014 0.050 0.15 0.06 0.19
Thanks

... I was told that heating a preharden (42HRc) steel rule (1.5" high X 0.083 thick) for bending a bit is worst than heating it throughly (not melting). it has something to do with the fact that the steel becomes harder before it gets softer. now limited experimenting seems to support this...
Hello,
What effects would air, water or oil quenching have on 1045 steel if a section (1/2 wide x 2 high x 3/16 thick) is heated with a oxyfuel to red hot condition? Would I regain or keep the microstructure/hardness?
I have a clicker cutting die (44 HRc body, 52 HRc cutting edge) where I need...
Hello,
I had done hardeness analysis of a HF induction harden cutting blade (1045 steel) which shows a heat effected zone (HAF) about 0.7mm from cutting tip at ~ 32HRc to about 1.0mm, while tip hardness is ~ 52 HRc and body hardness is 44 HRc.
I was under the impression that HAF is not...
