Interesting. This was discussed shortly on alt.machines.cnc last year. No real answers, either. Here are some of the responses ...
------------------ As to the original choice of letters G and M, there really was not much to choose from after omitting some obvious ones (of course, perhaps they only seem obvious because I've used them for so long): Linear: XYZ UVW PQR IJK Rotary: ABC Technology: S F T Numbering: N This leaves D E G H L M O. ------------------ Although some have suggested it came from Gerber plotting codes, the actual origin is probably in the APT programming language where moves were GOTO, GORT, GOLT, GOFWD, etc. ------------------ Joseph Jacquard said "Gee" when it worked. Then "mmmm", what else can I do with this stuff? ------------------ ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, April 03, 2003 12:49 PM Subject: [mfg-smartcam] What's the "G" stand for? > Hi all, > Maybe this is simple, or maybe we will have some fun with it. > I was just asked this question: > What does the "G" stand for in g-code?
