CNC Dictionary

[BobWarfield]

I made a CNC Dictionary for those who want to learn more. Since I am in that category, there may be some errors and ommissions!

Nice Dictionary Bob. That must have taken a while. There are a few more ommissions I found at a glance.

CNC Programming option Incremental (G91 for Milling)(U&W for Turning)

File Extensions for CAD;
ASE Files; 3ds MAX ASCII Export files AutoDesk
DWG Files; Pro/Engineer and AutoCAD/AutoDesk
3dm Files; Rhino Files
STEP Files; ISO-10303 STEP Product Data

It looks really good and is informative.

Nice work!!!!!

under N you need to add newspaper with the statemant that read "Paperwork that is done every day by operator"

[BobWarfield]

Thanks all, I have added the suggestions, except for the one on Newspaper, though I did get a good giggle from it!

The STEP standard sounds interesting from what little I read about it.

Cheers,

Is it simple to add 'NEXT' and 'PREVIOUS' near your 'BACK TO...' at the bottom of each page. For those of us who don't have a life and read dictionaries for relaxation it would save (two ... wrong) one mouse click per page.

PS: Delrin is pure acetal, no filler.

Bob, Regarding the definition of quadrature, it is often used wrongly and can cause confusion. The first part of the definition is right:
"The name derives because there is a 90 degree phase difference between the two signals."
The next line is where it is often used wrongly to describe the increase in resolution:
"The quadrature technique also produces more resolution."

It maybe should read 'The basic resolution can be increased by multiplying the quadrature signal by 4.'
because the quadrature signal does not on its own increase the resolution, the four edges of the two signals are used for this.
I often hear a comment like 'I have a 1000 quadrature encoder', when what they mean is they have a 250 count quadrature encoder and it is 1000 counts when x4.
Sorry to be pedantic, but although you may have intended this, it could be misconstrued.

Very well done. Thanks for sharing it.

Way to go Bob!
Have you been Googling much?

Too bad something like this can't be accessable from a simply button on the Zone, instead of getting snowed under by thousands of new posts!


If I'm not mistaken, deleting the cookies on your computer removes your ability to edit and change your posts on CNCzone! But there may also be a time limit set by the SYSOP at the server level as well!


Also, adding a POLL to the post keeps it alive much longer too!
Keep up the good work!

Gentlemen, thank you so much for your kind assistance in correcting and enhancing the CNC Dictionary. I've incorporated all the latest suggestions.

By all means, please be pedantic and critical. As I mentioned, I'm a student here too. The corrections are a vehicle to correct my misapprehensions before they become too firmly rooted.

Best,

BW

PS Widgit, a gold star, aw, you shouldn't have!

I suppose the moderators could choose to make it sticky, add a link somewhere on the Zone, or put it into a FAQ somewhere.

DNC - Direct Numerical Control is synonymous with Drip Feeding.

The definition you have is the one for Distributed Numerical Control. There was a discussion about this in a thread recently; one of Widgitmaster's polls if I remember correctly.

To add a little to what Geof is saying.

DNC-Direct Numerical Control is synonymous with Drip Feeding from a PC to the Machine Controller via RS232C, RS422, FACIT4070 Interfaces, or Ethernet Connection.

Sorry to correct your definition Geof, but students need to have just a little more info. And this is a dictionary for the experienced as well as the inexperienced. No Pun intended.
