gear programming for sprockets

[jrykrl]

I can't figure out how to use this to make a sprocket for a bicycle, or motorbike.

any help here would be great

[Rick Damiani]

Try the root radius to 'Full Radius'. If you have all the other parameters correct, that should make the sprocket for you.

Usually i use mechanical desktop to draw my sprockets, they are right on the 2D menu, pick the chain size, how many teeth, then .DXF them to mastercam and cut.

[John Summers]

Look for SPROCKET.MPK in the TEXT_&_POST_FILES_&_MISC folder. After you unpack it, open SPROCKET.PST with an editor, just to read the instructions. The method of construction is right out of Machinery's Handbook. Let me know if you have trouble, or even if you don't.

Ok John that was very cool I see antoehr little thing to play with. I am wondering how did you pack all that up like that in soemthing native to Mastercam but be a self extractable is this soemthing done in mastercam or by some other program.

 

I can see this as a great archieve tool is the only reason I ask.

One of our customers has written a C-Hook for drawing sprockets. If you guys are interested, I can get his permission to send it out.

 

Just let me know!

i do simtech...thanx very much

[John Summers]

Millman: I don't fully understand your question, but here is the answer. MP makes a great stand-alone language. MP.DLL is the exec for all postprocessors. The -.PST file is a configuration file where you put all your code, so you are rarely conscious that the exec exists. You write a 'post' (xxx.pst), but have a dummy input (xxx.nci). The postblock PQ is accessed before anything is read from the -.NCI file, so do all your work from the PQ postblock. You can have inputs from prompts or the 'buffers' (xxx.TXT files).

Simtech, thanx for the c-hook, it rocks

[Scott Bond]

Good Morning all

Simtech, I would like to try your custermers Chook, could you email it to me?

I make sprockets for BMX,they have no Derailer to keep the chain tentioned (sp),so I alter the teeth for each config(no of teeth) to eliminate drag.

Then I ran each size on my bike to where it in, Re-CMM inspect it, and then adjust the Programm [for that wear] on each size.

Now when a BMX racer puts one of my new Chain rings on his bike it is "Race Ready".

Well guys, here is the revised posting I've made earlier.

 

My customer has translated the C-hook in English with a text file explaining the functionnality of the product.

 

The C-hook is available for the general public.

Hi Luc

 

I tried it , it only has a few questions so being in French didn't matter.

For my use it didn't help my project any more than our existing gear chook.

[jrykrl]

It works perfect for my app.

Thanx again Luc
