Oi-TC allows the editing of the individual items in a block, so there is no pre-selection of a letter.
Maybe a parameter thing, but can be done for sure on mine.

Huhh.. all in one breath...
Ok, No, the Haas does not need modal G-codes written on each block, neither does the unchanged coordinates. I just prefer to do them for these reasons.
The G-code...

The jumping around is there ( unfortunately) but it isn't caused by the G41/42.
It happens during TypeII roughing, regardless of comp.
If you run the above code without comp, it will...

Again, my non utilization of macros is a preference, not a "dogma". Your useage of it is well warranted and is likely more efficient than individual coding.

Second, the tool pushing...

G-code

First off, using Macros does have it's place and I have nothing against folks using them. I don't use them for the simple reason that if a part is unique, then there is no justification for...

Me? Dogmatic? :boxing:

I just figure that keeping rigidly to a technique that works every time, all the time is a best way to standardize programming.

As Geof said about the potential error.
IOW if you miss something, you'll know it.

Additionally, since every move depends on the previous, there is very little you can do about accuracy.
If you...

You may have a point about your own programming style, as long as you remain anal about making sure the G91 does not "stick".
I OTOH prefer writing that out longhand specifying each pass with it's...

Duhhhh on the threadmilling part.
Not that it is the only way, but is certainly more convenient, in fact I use it too.
Sorry 'bout that.

As far as helical on a Haas, this will do a helical...

The point is, I like to restrict my part program to actually cut the part, while setup should include the setup of tools an fixtures.
If there is any discrepancy in the setup from one time...

Since all of my previous attempts at asking folks have been utterly futile, I'll ask again.
What is the advantage of using G10 on a machinetool - ANY MACHINETOOL - that has multiple workoffset...

First, you do as Dcoupar says. Use G28 or G00 G53 X0 Y0 Z0 to move absolute home, then type G92 X0 Y0 Z0.

Second, you cancel it in your head by NEVER EVER using it again!!!:stickpoke

Geof's...

Actually D0 works just as good without having to edit the code to remove existing G4x commands.
In fact you gotta specify D0 on a G12 or G13 block as it automatically calls the active D-word.

For one-offs or short runs it is a hit or miss.
If your tailstock is out though, it should be right on once you figured out the amount of compensation needed.
For production runs, there is no way...

Yeah, but you know I have also kissed a great deal of frogs with them and kinda worried.
Typically Sam makes a decent beer, otherwise German is where it's at.

Oh well..... I guess I'm a hypocrat in some things....

How'bout this. A fresh keg of the finest Sam Adams specialty of the season?

As of 04/30/08, Haas has 271 CNC machinetools in the facility and approx. 170 of which is HAAS machines of various models.
The non HAAS machines include older, mainly Hitachi workcells and lathes...

I have to make a guess here that your machine does not have the option of cutter comp during G71 cycle.
Oddly enough my Mori manual clearly states that G41/G42 is not functional in the...

Actually, when part length is of a concern, you must hold the OD to be clamped withing tighter tolerances.
By calculation, the 5C collet will have a 3 to 1 ratio. IOW .001 change in the diameter...

Yup, as Cogsman said.
Touch off Z at part face, then deduct 1/2 toolR from the offset in the offset register.
It's gotta work!!!

Lowe

I jut re-read your original post and realized that you're using a .0312R tool.
My bad!!! The start points in Z must be moved away appropriately to allow the tool to fit in. With .0312...

Well Geof.... Here is my take on it.

I think it is nice for the right application.

Here is the problem though
Using the positive tool-length does not mean a different way of picking tools than Geof.
In fact it is identical.
The problem is that to be cost effective, accurate and...

Your first G76 line has a Q0. That is a min. DOC value.
I know if you omit it completely, the default from parameters takes over. In this case though you specify it to be 0. Not sure!?!

First of all, that code snippet without the starting X and Y coords is useless as none of the backp[lotters can figure out where the paths start from.
Also, you seem to have the modal coords turned...
