I'm wondering in which cases radial approach works in z-level finishing. It appears that if you are restraining the toolpath by a boundary that it seldom works. The Help files say that if there is room then the radial approach IE depart will work, but if not room it defaults to vertical approach.

I was able by changing the way I finish the rest of the part, to shorten my tool stickout to 2.5 inches. I seem to be getting a good finish and by allowing .002 stock I am avoiding gouging the already finished surfaces even though it's defaulting to vertical approach>

Hi Mortek,

I use a screen capture program called 5clicks to take screen shots. As you have found out, windows bitmap format is huge when using print screen to Paint.

I think you can use "5 clicks" for 30 days free, then you need to register, but it is well worth it. Most screen shots saved in png format are less than 70k, and look better than jpg.

I have a few imcremental macros that I have figured out for thread milling. I have these set up in custom code, but I was puzzling about how to make a neat insertion into the NC manager, in the event that I had a several holes to do.

The method I used was to set up a special machine cycle which I call thread mill.
Start lines:
{/X}{/Y} 'movement to first hole

Mid lines: call the macro
/N (Bandit subroutine macro call)
{/X}{/Y} 'move to next position

End lines
/N (final sub call)
N (unconditional jump in main program, Bandit style)

I call this special cycle then, just like any other drill cycle, and then insert the custom macro code after it, a simple 2 step process in the NC manager.

When I post the code, my subroutine macro is posted right inside the main program body. After posting, I then have to find the appropriate line number for the start of the macro, and paste this after each instance of "/N".

Then, I find the line number of the line following the end of the macro, and paste that in after the "N", which in Bandit code, forces the main program to skip ahead past the macro in the main program, when it gets to it. Thus, the main program can execute smoothly afterwards for subsequent processes.

I don't know if this will help or hinder anybody, since most of you use ISO code. But, it works better than just plopping gobs of macro code into your program, because then the NC manager's normal method of laying out the code for this tool, etc, will come out neat and correct, with a minimum of fuss.

I posted this on the other board. But I wanted to post it here as well. Enjoy.

Guys,

Here's a tip that Bob F. turned me on to when selecting edges to fillet.

After you select the fillet function and you start to go around the part to select edges, you can zoom in or out, with out "losing" the funtion, by placing your curser over the area you want to look at and press the "+"(plus key) to zoom in and the"-"( minus key) to zoom out.
This way you can zoom right in on your edges and make sure that you select all the ones you need to make fillet work.

Where you place the cursor becomes the center of your screen.

This works on both Xp series and Mill 2000/2004.
And in Xp series you can use the wheel on the mouse to rotate the part with out losing the funtion.

This may work for other things as well.

Pretty cool stuff.

Thanks Bob for the tip.

WMS,

Is this something you have to turn on somewhere? I just tried it in ver. 4.36 of Mill Prof 2000 and could not get it to work no matter what I do.


Okay I take that back. The"+ or -" Key on the number pad of the keyboard works.

If there is one thing I've learned from Hu, it is "don't buy anything with a bandit controller".

It seems you spend more time messing around with the programming than cutting material.

I'm so glad I have a machine that reads straight forward G code and macros without any propriatary weirdness.

[HuFlungDung]

You are quite right Keith, they do take some fooling with, because they were originally built on a competitive system to ISO, but then they aren't nearly as tough as some of the "conversationals" that I've seen guys working with (trying to create Gcode posts)

Bandit is pretty much extinct, anyway, and service and boards are hard to come by, but the Shadow came along so that "something" would be able to run existing programs. It is kind of the "inbetween stage" between the homebuilts the guys on these forums are building, and big name cnc's.

But, it moves the cutter in all three axis, that's all I care about. Its actually very handy to run, if you like living on the edge: it will execute any line of code you give it without a big song and dance first.

hi keith
thats the thing i love about ONECNC
no matter if you have a old controller
or a new controller
onecnc is flexable in posting toolpaths to suit your controller
old or new

Guys,

Here is Link to a new "Third Party" book that is due to be released December 2003.

One of the advantages of being a hybrid CAD/CAM system is when dealing with imported models it is not necessary to Stitch or sew surfaces together for machining.

OneCNC CAD/CAM software recognizes tangent surfaces, even when not closed to form a water tight model, and allows machining of imperfect models by mathematically "healing" the model during import and then re-examining the model again during the generation of tool paths.

This ability is possible because OneCNC is built on solids originally, not as an after thought or third party add-on. So therefore OneCNC treats a single surface, or multiple surfaces as solids, even when their not.

This makes OneCNC uniquely capable of reducing programming time and so is easier to use so you can focus on programming, rather than wasting time repairing models.

With OneCNC its as simple as import and machine.
