Tree Mill cutter comp code

[Garutek]

Does anyone have a G code example of a Tree mill type II code with cutter compensation or even possibly lenght comp. The one with (0)'s not (E)'s.

I cannot seem to figure out the G41 -42 or 43or "C" Variable and just get errors.

Thanks!

Tree mill??

[Garutek]

Tree mills are discontinued now but still around. They were made in Racine WIS till ? 1995?

[HEAVY METAL]

my tree mills have dynapath controls and one has vickers pc2100 . what are you working with

[Fred @ Slate Industries]

I have the Post / Code for a Tree with an Anilam 1400 controller, Will that help you

(Just sold the Tree for $750.00 today too the Service guy who worked on it for a decade)

[Garutek]

Thanks gents, I have dynapath controls I'm not near them now but I believe they all also say Anilam.

Can either of you use cutter comp? my dealer rep is working with me and we tried the newest post, but I can't tell him what we need to change. If possible please show some code if it works, this would be a great help. I'll check back tomorrow during the day!

Comp you bet, although the lead in and out must be

the radius of the cutter minimum or it will error

out at the controller,so you have to get creative in MC how you do that since its not gouge checked

by MC.

I'll catch you tommorrow a.m.

I have a Lagun with a dynapath control.

On my mach. the caharacter insid the parenteses is the conversationa event type. I program in MC w/ wear comp.

 

(9) is a preparatory funtion

(0) is a rapid move

(1) is a linear move at a F

(2) is circular interpolation w/D indicating direction

C1 turns cutter comp on

C0 turns it off

I just started w/ the conversational dynapath post.

Our Tree VMCs have AutoconDynapth controls on them. We don't need to call out "D" or "H" for comps, the "T" call takes care of both.

 

If you use wear type compensation in Mastercam you'll be better off. The code will be cleaner and easier to read. On ours, when using Control Type comp, we had to turn off cutter comp with an incremental zero move above then turn it on with another linear move and then feed to depth.

 

example of our control comp code:

We switched to wear type comp about 5 years ago and our code looks very much the same as 3rd String's now. The latest and greatest post from CNC should get you going in the right direction with wear.

i've been having a problem with comp on linear milling. the comp will pick at start of contour and not get to position to the end of countour on a staright line. lets say i have -.001 wear in offset page of machine the tool does not move off at start .0005 . it gradually moves into position by the time it reaches the end of toolpath. result is a out of square edge. works find in a arc or circular path. something to do with the incr move before you turn comp on i believe

[htm01]

do you have tangent instead of perp. checked? that would do that

[dwsz71]

Heavy,

 

is your code similar to what I posted (control) or 3rd String's (wear, I'm assuming)? Could we see a sample? I only ask because you said "incr move before you turn comp on". Using wear type comp doesn't require me to use the incremental move/comp off line any longer.

htm01,

 

the tool should still be in the correct position at the end of the lead-in and before it starts it's move across the part though, shouldn't it? Would it really matter if the lead-in was tangent or perpendicular? Using control comp as I posted above, my lead-ins were all tangent. The machine would make a physical 90° X move on line "N0095(1)Y0/F80C0$" if the tool diameter offset was >0. Using wear type comp I have forgone this move and can now just make small perpendicular lead-ins at cutting depth.

dave if i understand you right you need to make a perp. lead in to make it work correctly not a tangent.

[3rdstring]

I use a tangent lead in/out most of the time.

I had technical dificulties on friday so I could not log in.

I'll try again Monday.

my code matches and I was using wear compensation.

I'm thinknn :

The line moves did not equal the tool table offset amount. I had a diameter (.464) entered instead of the diameter differance (.018 rad or .036 dia). Dahh.

Thanks this really helps!
