Probing inner radius
2 Questions: 1) Using F360, I set a partial hole probe (probes 3 points of radius). How do I export this data on a Haas VF-2SSYT? Either as XY locations or as a radius, whichever is simpler. 2) Also, how can I set a series of probes, and export the XYZ locations, and map out the shape...- teachme

Camera precision measuring device?
Problem: measuring internal radii, splines, geometry, that can't be accessed by probes or other means. Currently what Im doing: using a regular camera at highest focal length, measuring the object with caliper, adding the picture to a CAD software, adjusting image to size Any technologies... -

Material choice for DMLS engagement ring
The prongs go ~0.6 mm past the diamond edge towards the center. Ill try extending them further, good idea. And I also considered mechanically bonding the split. Perhaps adding a few holes extending through both ends, and suturing with a metal wire. Not sure Id trust any soldering or welding so...- teachme

Material choice for DMLS engagement ring
The ring will be split in the middle. So the individual prongs aren't flexing. The arrows show the direction of spring-back. And likewise reverse to flex open.- teachme

Material choice for DMLS engagement ring
I found an alternative design that would require spring-back of the prongs. The last concern is fracturing - how far can I bend and at what thickness/geometry. Also strength, will it be flimsy Thank you for your help and advice!- teachme

Which of the 3 has the highest resilience? I need to bend it about 0.5 mm, and have it spring back- teachme

Material choice for DMLS engagement ring
My material choices are: •Cobalt Chrome •Titanium(Ti6Al4V) •Stainless Steel(17-4 PH) I need a metal that won't fracture with the least resilience possible. To prevent the prongs from breaking or springing back. (image for reference only)- teachme

Loud stepper resonance cure?
I bolted a NEMA-23 to a 1'x1' aluminum panel, 13/64"(5 mm) thick. The resonance is extremely loud. Full stepping between 100-15 RPM. Even when adding padding between the motor/panel. (Its almost inaudible when not fixed to the panel) Any methods to reduce it as much as possible or completely? -

Shaft torque required - calculation
Why are you on a thread posting if you dont have answers :nutter: and you could apply that same logic to every thread on this forum -

Shaft torque required - calculation
In this case, lets assume the barrel is a solid mass, no friction variables. Can you show your work? Doesn't look like you factored in load inertia or acceleration. -

Starting to realize this is the wrong website to ask this question. -

Shaft torque required - calculation
Judging by your comment, you wouldn't know the answer anyway. The torque is to rotate the 1" shaft (look at diagram for "chain/gear")... and the title says, "SHAFT TORQUE required". Did you even read the question lol. Calculating torque you need "time to accelerate load" ..(5 rpm - in 1 second)... -

Shaft torque required - calculation
How would torque be calculated to rotate a 200 lbm drum on parallel shafts? 1" shafts rotate same direction, inversely turning barrel(15.7" OD). 5 rpm - in 1 second. Gear ratio(15.74:1) Variable 1: barrel is not fixed on any axis Variable 2: barrel rotation is halted (shafts continue rotating) -

Spur gear question
But considering the tangent points on each set of rollers, the smaller set is moving twice as fast. Wouldn't it mean it's moving the tape twice as fast, faster than the large set can move it through? And the backing wind-up circumference is changing with every revolution. -

Spur gear question
This may be a relatively simple design, but hard for me to understand. The task: tape (red) and tape backing(purple), will pass through these orange rollers. The 1st and 2nd set of rollers need to move the tape at the exact same speed, and simultaneously wind up the backing matching the... -

Combination bearing torque
Can you easily spin a 1" OD combination tapered bearing by hand, with 200 lbs of thrust force on the bearing? The thrust is rated for 900 lbs. The bearing fixture will be compressed against a paper roll (50 lbs), and the paper has to roll off without ripping (with starting torque). Just need a...
