Hex bar will definitely save you cycle time, but you will also go through turning tools faster as the interrupted / varying depth of cut will cause the turning tools(s) to break down faster.

Thanks; I've been considering either that or a vacuum fixture for op 20.
I appreciate the input.
Our sales department sold a promise that I have been tasked with fulfilling, but I do not have a good idea how to proceed... Hopefully there are some workholding experts here who know an answer...

There are many reasons for Okuma re-loading the program under certain circumstances. One reason is the use of .ssb routines. If a subprogram has been edited, there is really no way for the control...
Tell your CAM system the full diameter of the tool you are planning on using. (That is, the full diameter of a new tool.)
Make certain to have the CAM software output the positions of the center...
My "late-in-the-day-punt" ideas sometimes give happy little surprises; I had a similar problem on a Citizen several years ago - the fix was surprisingly simple.
Use an opposite-handed threading...
I dug through some of my old programs and came up with this:
G68.1 X Y Z R I J K
where
X = X dimension of the hole
Y = Y dimension of the hole
Z = Z dimension of the hole
R = Degrees to...
It has been a few years, so I will have to defer to a few of the experts in this forum.
Angled holes are a simple matter of doing a G68 to rotate the coordinate plane, then just use a standard...
@Tech1AZ: Does the machine work at all using LaserDRW?
We have two different toolsetters at our shop (two different manufacturers) and have had a pretty significant list of issues with one of them - 2 software updates, hardware needing replaced, weeks...
For starters, I have found that reamers generally do best if they have a little more material, especially in aluminum - My rule of thumb is 10% of the finished diameter; which makes it right about a...
Wow, I'm sorry.
Maybe I should read the question before answering!
First of all, check out the picture here for some good direction; I believe this image is also in the Machinery's Handbook.

With very few (if any) exceptions, Left-hand threads are identical dimensionally to the same Right-hand thread.
Whatever dimensions a right-handed thread has will be the same for the left-handed...
I believe you said 5 flutes on this tool?
We really need to know the feedrate, whether in feed per minute, feed per rev, or feed per tooth.
You said it smells like it is burning - assuming it...
I've had great luck using a G34 move in Z, followed by another G34 with a very small (~.010") Z move and a large X move at the same feedrate (The Z is necessary so the control can apply the feedrate...
> no big diference between 2mm and 2.5mm so I cut same speed / same rpm
>The cut was very bad from the first track , like burning and brooke.
Actually, the difference is 25%, which is not a...
what kind / brand machine?
I've never seen a machine control have any issues because of the keyboard speed.
First thought: 0.2 for a depth of cut, especially on Aluminium, is very shallow. If it is 0.2 total, then it is only 0.1 per side... and that, in my experience, is too shallow a cut; the tool is...
Check the "shrink the diameter" line; my initial post had the message end with a square bracket rather than a parenthesis.
I'll be in the shop working on a few projects today; I'll plug this in and...
OK, I'm done playing with it...
I added RZLN variable, this will be the angle per straight-line move.
Setting it at 90, for example, will produce a square shape (a "squiral?"), at 45 will give an...

If you want it in true G01/G02 arcs, then you are probably not going to find a "true" spiral as an answer.
But if you break it up into small straight-line moves, it becomes pretty straightforward.
...
Glad it worked!
If the power drops out during a tool change, then the variable may still contain the previous tool number, and of course, manually changing a tool.
Huh.
I've always known them to be extremely helpful, even to the point of lending software support to a system created by a third party machine tool builder that used their own software to control...
VATOL is the tool number that is currently in the spindle on mills... a word of caution, VATOL contains the tool number from the most-recently completed tool change. 99% of the time, that should be...
Sorry, my bad... turning centers use VETLN rather than VATOL.
1. I've worked on a number of projects that were centered around Okuma machines - and every time, I am surprised by their rigidity, stability, and accuracy. We set up 7 machines, fully tooled (50+...
VATOL is the tool currently in the spindle, so how about:

I get the feeling you've been in the industry as long as I have.
"G Code" has become a generic term (in Ohio, anyway!) for any sort of program code, regardless if MDI or full-blown program.
