Thread inserts like we common used in aluminium castings are more stronger than aluminium threads, you can make the inserts much bigger than thread size, and add multiple groves to avoid to be pulled out.

Cant see the thickness, but its a really challenging project for only bending, as I can see thickness according to drawing scale. Use thicker material and grinding after bending is a not bad idea.

Cause 3# is very rare in CNC program. Machines are more trustable than human beings, 99.999% CNC defects are caused by human factors. In factory, if there are a complex CNC processe involve multipe clampings, especially for large quantity orders, factory will use more machines, each machine...

Windows 11 system, my CATIA is V5R21

Two galvanization methods, hot galvanization and cold galvanization. Its helpful but not necessary to added anti-rust oil on cold galvanization part, because anti-rust performance of cold galvanization is not stronger enough for severe environment, its salt spray test time is 24-72 hours...

Try to use guides instead of coupling

This is a part we are producing, using 17-4PH H1075

Different thickness will have different effects on heat treatment. Compare the hardness, depth of hardness between part and specimens, maybe helpful to know the reason

No need to worry about fastening force of shoulder screw if make it like this.

If you use Electric torque wrench, do not design according to 216Nm, its just a static torque, impulsive torque while tightening must be considered.

It'll be better to machie threads before heat treatment, to reduce stress while machining.

Sure, like these

1. Check whether the hardness is in correct range. 2. Take a torsional rigidity text in a simulated aseembly condition (if test cost is not in consideration), compare result with theoretical value.

Working well, I hear you from China

CuZn40 ( C28000) and CuZn39Pb2 (C37700) are common materials, cast by gravity casting(permanent mold casting) or precision casting.

Good idea Lego(y) Is lightweight of gearbox casing in your next plan? Otherwise its rotation will case a lot of energy consumption

Quality control during desinging is very important, its not cost waste nor time consuming; on the contrary, good quality control can avoid bad design, save cost and money. We used to involved in a project collaborated with an innovation company, its a snow plow. This project was started at...

Firstly, we need to know Crystalline fracture firstly: 1. What is Crystalline fracture? A crystalline fracture is a type of fracture that occurs in steel when it fails under load without exhibiting significant macroscopic deformation. The fracture surface is generally flat, with a bright gray...

I haven’t seen such a website. But I have a reference list of casting steels with their chem and mech properties. If it would be helpful, I'd be happy to share this list with anyone.

All programmers know that Do Not to "modify" the BUGs if they have no affect on your program
