I've got D problem..

[MetalFlake]

..I need D answer.

 

My post sticks a D on every line after the G41 like this:

 

G03 G41 D2 Y.3663 I0. J.1382

D2 Y-.1863 I0. J-.2763

D2 Y.3663 I0. J.2763

D2 X4.3295 Y.364 I0. J-.2763

D2 X4.365 Y.09 I.0177 J-.137

G01 G40

G03 G41 D2 Y.3663 I0. J.1382

D2 Y-.1863 I0. J-.2763

D2 Y.3663 I0. J.2763

D2 X4.3295 Y.364 I0. J-.2763

D2 X4.365 Y.09 I.0177 J-.137

G01 G40.....

 

 

I can't see why. Can someone please help me out?

 

Many thanks!!

Thats easy,

The g40 cancels the d offset call, and clears it from the machine memory.

The "D" is always called with a cutter comp call so the machine knows what offset to use. You can use different "D" numbers for the same tool number.

In a Haas you have to set a parameter to do this, but it works there also,

oes your pccdia block look like this?

 

pccdia #Cutter Compensation

#Force Dxx#

if prv_cc_pos <> cc_pos & cc_pos, prv_tloffno = c9k

sccomp

if cc_pos, tloffno

[MetalFlake]

Looks like this: (I have to have all D2's no matter what tool in the spindle..for a Makino A88E horizontal cell)

 

 

pccdia #Cutter Compensation

#Force Dxx#

if prv_cc_pos <> cc_pos & cc_pos, prv_tloffno = c9k

sccomp

#if cc_pos, tloffno

if cc_pos, "D2"

Change the following line:

 

if cc_pos, "D2"

 

to look like the one in my previous post.

[MetalFlake]

Like I said....I have to have D2 on ALL G41 lines no matter what tool in the spindle T4, T9, T54435

 

Thats why I forced the "D2" but I didn't think it would stick it on every G1, G2, G3 line.

 

Thats where my problem is.

MetalFlake,

 

FYI: Another method to consider.

 

I have ran Makino's for many years and what I did was to put the D2 on the tool as I always had the tool in the tool library first. This way if you had that certain part, IE: where you had a hole and slot that were +/- .0002, you could use "nc side" d#'s if you wanted to. I did "hardcode" the H1 on the Tool length in the post for safety though.

 

I ran two A-88-e machines at my last job for about two years.

 

Mastercam + Makino = Very effective combo!

I'll look at it this weekend.

[Christian Raebild]

Change it to this:

 

pccdia #Cutter Compensation

#Force Dxx#

tloffno = 2

if prv_cc_pos <> cc_pos & cc_pos, prv_tloffno = c9k

sccomp

if cc_pos, tloffno

 

Then the D number will always be D2, and it will only come out on the line with G41 or G42.

That did it! 3 free drinks of youre choice are waiting for you in Everett,WA.

MetalFlake,

 

What are you going to do when you need more than one d# per tool? such as in very close tolerance work?

 

I guess if there is no chance of that, then hard code is OK?

 

Thanks,

 

Mike

You can force the D2 with this:

 

 

code:

---

 sccomp

if cc_pos, "D2"

---

Hope this helps

Michael Whitten,

 

The control automagically applies what number is in that tools dia wear setting. Kinda like a accramatic that doesn't even need a D number. It knows what tool is in the spindle.

MetalFlake,

 

I fully understand the way Makinos work. I have programmed and setup 9 different ones. What I am saying is that for default you should have a "D2" but if you get it for the tool you can change it for special uses etc.

 

IOW, you can use D2 for the regular stuf and D201 and D202 for close holes on a part. what if all your holes and slots are +-.0002. one D# will not do it.

Here, for the tight stuff, we would have a different tool come in and net that feature.

MetalFlake,

 

What always seems to happen to me is that I have say a .2500 slot and hole called out to +.0002/-.000. Most machines will have to have a different D# value for each.

 

I realize that you can get by without it but it adds more flexability for free.
