Does anyone have any information or ideas on straightness inspection of thin bars.
I am trying to measure 1/4 aluminum extruded material to what the standard, I believe is, .002 / Ft.
We are buying 12Ft bars. The finished product is 18" long.
Any advice? Thank you in advance
Hello
I'm trying to determine the minimum and maximum force that we can expect in lbs measured after we press a pin into a hole.
The pin is .0582/.0578 Dia x .1 long 420 SS ground finish
The hole is .0579/.0574. 17-4 stamped in .055/.053 thick material 50/50 shear to break
No lubrication...
Hello, I'm having a debate with others to interpret the assumed flatness or straightness on a thickness or "bow" callout. The spec is Ansi 14.5M-1982. The thickness callout is .2787-.2745. Do I get RFS and the measured "bow" or do I have to place the part down and the entire form has to fit...
I'm trying to develope a simple calculator (in Excel)to compute machine hourly rate and operator hourly rate, combined with net profit, in order decide whether to run 1 machine with one operator (eg. with thruput efficiency of 97%) or two machines with one operator (eg. with thruput efficiency...
I have an extruded shape - round on the outside and round except two "key-ways" 180 degrees apart on the inside. The OD is Datum A and the keyways are Datum B. I have to machine a slot in the end; Looking down at the end (the cross section if you will) I will endmill a slot central to a depth...
Hello, in a press shop I need to weigh very small parts (30-20 g) and need to read to +/- .5 g. I'm afraid the vibrations may cause incorrect readings. Is there any dampening materials or methods I can use to isolate the measuring equipment. Also how can I measure magnitude in the shop. Thanks
Can someone please help me with the following problem. I need to bend a 1/8 dia x 7.2in long solid 303ss rod into a 5in radius x 75 deg with a .75in straight section at the end. I was thinking about clamping the .75 straight section and proceed to roller bend it on a radius anvil. I'm not really...
Can some tell me how to create the following:
like 1/2 cutter in the center of the axis constantly and picture the cutter moving along the axis as the cylinder is rotating. And not necessarily a helical shape. In fact it looks like a bolt action shape of a barrel. Thanks
Could someone help me out I'm trying to cut 90 durometer rubber. The geometry is OD of 1.5x .5 long step down to OD 1.375 x .5 long with 2 (.5 dia) x .5 deep flat bottom holes on it. tolerance is +/- .015. All dims in inches. I tried sharp turn tool, sharp endmills, fast, slow. Is grinding...
I'm not familiar with MIL specs. I was waondering if the following metal gets heat treated:
[UNS S17400(17-4PH) per ASTM A564 aged to condition H1150]. The bar that we received said 17-4 condition A. and also do we machine this part before heat treat if it gets heat treated. How does it react in...
I'm running a flange through solidworks Cosmos Express FEA and I'm finding if I put a small fillet in the inside corner, say .06in, the part is substantially weaker than if there was no fillet. As I increment up to .25 Rad, it equals the strength of the original sharp corner. Can someone tell me...
Can someone please help me change my dimension colors and my sketch entities back to black and gray. This problem is only in drawings. The dimensions have turned to red and the sketch entities are now dark red. This all happened after I used the task scheduler to try to predefine some drawing...
Is there a way to have zero thickness in SW 2004? I dont want to disjoint anything, I might want to put a c'bore with 3/8 dia 3/16 away from the edge for example. I know i can lie to it, but is there is an option for that? Thanks
Can someone direct me to the proper design standard for the following machine.
It is a fork lift type machine that is on a railroad type track that lifts a ring (125"OD X 55" height 7500lb weight). the lift has 2 "forks" on bottom and 2 on top. The machine moves to the ring, the two forks on...
Can someone tell me the saftey factor for a lift truck. Like a special fork lift. no one will be under it. It has to lift 8000lb, flip it then bring back down.
