@mfgenggear nice that should help. Also sitting in a dark room looking at a screen doesn't help too haha.
Overall update is my BD partner wants to proceed with 3D Hubs despite my warnings about the spline cut. I'm waiting on responses from ASH and Broach Masters. Waiting to hear back. 3D Hubs...
@mfgenggear for your headaches, maybe wearing Blue-Light-Filtering Lenses would help you out? I personally run blue light filter (close to max dim) 24/7 on all my computers. On windows it is located on the bottom right windows center... right click to alter how much it dims. College killed my...
"but causes issues during heat treat, do to distortion."
With that said, does anyone how what affects EDM will have on spline strength or distortion with 4340 alloy? I can't find concrete essays about the localized effects from cutting with this method. I am doing no post processing. This...
@mfgenggear makes sense but I need to sleep on that info. I'm just confused on your last two sentences there:
"But with out gages there is an over tighten of tooth thickness size.
A gage gives more tolerances."
I am located in Seattle, not CA. I only was mentioning CA because I know my real...
@mfgenggear right. But out of curiosity is my though process right? class 6 seemed good in between from what I know with backlash per business partner's provided insight/info... but what you're saying makes sense: there isn't a concrete way to know with the way I have gone about this.
We have...
@spigor I never got to EDM the pink one you made or the class 5 according to B92.1-1996 I made. All I got to confirm was the green one you made fit well, how tight not sure because my business partner in a different state felt it out. I know I do not have all info in that table and sorry I...
I should also say the drawing has a table of:
Module
Number of Teeth
Pressure Angle
Circular Space Width
Major Dia
Minor Dia
Then under that it says: "Spline Standard in accordance to ANSI 92.1-1996 Table 57 Class 7.
I will obviously send them the DXF file for their reference, along with it...
@spigor right circular space width not thickness. Would it safe to say the green plot isn't following the standard at all then? Or could it really be class 7 and just worn out a bit, thus skewing the results? I am not sure what to do here and wish I noticed this earlier. I was hoping to put a...
@mfgenggear I will get back to you on that! I'm going to make a new post here soon. I have another 4 projects I've picked up (one part has two splines this time ohhh boy!) on since someone else has now starting offering a full dog box 4 speed transmission kit. Obviously it's expensive and I no...
mfgenggear, totally agree. That is what my professors always said too [bigsmile]. I want to write my own because I'll need to anyways and it's a good thing to have on my tool belt. I'm going to soon start back up on my original project that got me started on this in the beginning; custom 4th...
Cool! I'll look into that but utilize SolidWorks and Matlab/VBA. I've found some pre-written programs in VBA that works with SolidWorks but no luck with them yet. I'll keep digging. Thanks again
Nevermind sorry. It was a solidworks problem I believe. I imported it via mm instead inches and it came back to scale. Matches well with mine too. Thanks lfw618 for that modeling tip and Spigor for dxf ;)
Spigor,
When I pop in your dxf file into solidworks or eDrawings (to compare to mine), the dimensions are way off. I'm getting a diameter of around 24 inches. Am I missing something here?
Wow thanks everyone for the help! Once again I appreciate the knowledge.
As for my last post, what I meant to say was "fully define" the spline the way I measured it described above, then use that model to measure other features that are spline specific. I know I need more info to put on the...
spigor: If you could do a, b, and c that would be awesome! I'd owe you a steak dinner haha. I haven't sent your original file out for printing yet because I want all three. Also keep in mind I have limited access with work machines for personal projects; don't want to stretch these freedoms and...
Hi everyone,
So I think I'll go with a Mylar sheet drawing and pay for that service. However I can't seem to find a trustworthy/ legit website to convert my involute spline geometry to dxf file. I've started to model it in Solidworks but not sure it'll come out right. Would love to check my work.
