Title: can someone tell what the letter H and D stand for
Post by: josh on August 22, 2008, 01:42:53 AM

I have been running my programs on mach but I dont know what the letter (H) stands for it appears after every tool change and the only thing that appears is H0
do I have to input some in there. and also there is the letter(D) it always appears after the g41 and g43 but it also say D0.
I am using cutter comp. when I do my toolpath. I use mastercam to generate my g-code.
can some let me know how to use those 2 letters.
here is one of my programs.

D = Cutter diameter/radius offset
H = Tool length offset

D is the tool # when using G41/G42

hello and thanks for the replys
so if D=the tool number
and if H=tool lenght offset
what should I input on my code I have posted
or do I go to my table offset and input something in there
I am still unsure  on how they work if you could please explain a little more
on how to use them I would appreciated. sorry but this is kind of new to me.
thanks again
josh

Never used it, but I believe H is the tool # as well, used for height offsets.

so let me get this straight
on my g- code that I have posted I would just leave H and D at 0
and since I am using cutter comp all that I have to input the tool diameter for each tool, on my tool table offset.
is that the way it works
or do I input (H1 for tool 1) (H2 for tool 2) ect.
my point being is how do I make it  smaller if the part being cut is to big (.010)

Change G41 D0 to D1 for tool 1, if that's what you're using. Then change the size of tool 1 in the tool table. Make the tool .010 smaller.

With G41/G42, if you want to specify the tool size instead of the tool #, use P instead of D. P is the tool radius, so for a .25 tool you'd use G41 P0.125.
