hi djdove,

you have a good idea there, and a good start on your website. If anyone else would give you tidbits to add, like rules of thumb that apply to machining and using tools, your site could quickly become a reference to everyone starting in the trade.

good luck!

Great effort my brother. I remember that enthusiasm and it's good to see that it's still alive, albeit in a different person :P I got something for your site. I would love to write an article on macro programming for you if you wouldn't mind. Heres a sample of my work I hope you will post on your site. Its a macro for Okuma turning centers which all but automates bar pulling. This is an alpha implementation and by no means finished, but I think adding some parametric goodness to your site may help it's over all appeal. It's a combo of two programs and both need to be present. The use of the macro goes like this.

(PART OFF TOOL)
G01 X0 F.004
CALL OBAR

Here are the programs

OBAR

V200=V200+1(INCREMENT COUNTER)

BARD=2.0(STOCK DIAMETER)

BARL=36.0(BAR LENGTH)

FFA=.02(FACE FINISH ALLOWANCE)

DROP=3.0(DESIRED DROP LENGTH LEFT IN CHUCK)

(*DO NOT EDIT BELOW THIS LINE*)

V199=VETLN(SETS THE TOOL # OF PART OFF TOOL IN V199)

VTOFX[1]=0(SETS THE X OFFSET FOR PULLER)

PARL=VSIOZ

PTCT=ROUND[BARL-DROP/[PARL+FFA]]
