The "Red arrow of doom" still gets me if I'm not paying attention. But all in all I like it because you know where your next path is going to be put. JM2C.

I agree the red arrow is much better now, but it still moves unpredictably. It just won’t stay where I put it!

John, maybe some people here think of you as a CNC employee.

[Mike S @ S4A]

naw, we just sell & support it

How 'bout a switch to lock the arrow at the bottom of the group?

[Elmer Fudd]

My sugestion for the red arrow af doom was to have it not move on its own. Keep it at the bottom unless you move it.

I use the breakthrough amount on rare occasions. No I have never scrapped a part from using it and I think I'm a fairly intelligent programmer. One less box doesn't make a person a more intelligent programmer.

John, I stand corrected. YOU coined that phrase. My Apologies.

I like to take credit for my "good work"

Guys,

 

Break through is not redundant. When using tabs, you use break through to cut into the spoil board without messing with the size of the tabs. If this were not there, you would have to increase the size of the tab by your break-through amount.

[Roger Peterson]

Unless break through does something I'm not aware of it works the same as setting negative Z stock to leave.

 

 

My only problem with the breakthrough function is that I have to open another dialog to see what it is set to. I use negative Z stock to leave which I can see at a glance.

[Alvaro Gil - Cimquest-inc.com]

No it does not do the same thing. When using tabs, it does not change the starting height of the tab, it leaves it in place and breaks through by that amount. So if your tab is .02" from the bottom of the part and you set a break through of .01", your tab will be unaffected.

 

if you use -.01" z stock, then you will have to change the size of your tab to .03" in order to make a .02" tab.

[Matthew Hajicek - Singularity]

Even in Mill I think it helps preserve the design intent of the operation. If I'm using a bullnose with a .030" corner radius and set a .035 break through, I don't need to refigure my depth of cut if I change to a flat endmill later. I can just change the breakthrough to .005" or whatever. While stock to leave may produce the same result and I don't recall ever using both at the same time, the term has a different meaning in my mind.

Alvaro,

Thanks for the info regarding Tab depth and breakthrough. I did not know that they were tied together.

[connormac]

I agree with Matt. I use depth tab to be thickness of the part. Use break thru to adjust how far past bottom tool will go.

 

But I use stock to leave for stock to finish pass on outside. I will use stock to leave and break thru.

[Roger Peterson]

+1 on partial tab depth, I don't believe it affects full height tabs, or onion skinning.

 

I set my depth to the depth of my geometry, I then use negative stock to leave to input my "breakthrough". The only reason I use negative stock to leave instead of breakthrough is because breakthrough requires that I open another dialog to check that value.
