Stupid planes question

[MIL-TFP-41]

Here is one I have always wondered.

 

What is the difference when you are in a toolpath between the Tool plane and the Comp/construction plane?

What situation would arise when they would not be the same? Aggregate head maybe?

I do know that bad things will happen if you somehow don't make them the same.....

If tool and comp planes do not match typically you'll get a warning that the planes are not perpendicular.

For aggregate programming you need a post with that functionality built in so you can program in the G18/19 planes.

This is actually a very good question... I have programmed a lot of multi-axis stuff where my "Tool Plane"  and my "Comp/Construction Plane" are always the same...

 

I'm wondering the same thing as MIL-TPF-41...

 

Under what circumstance would you want these to be different, if ever?

I think in all my years I have never seen them different and still have never understood why they are.

I have used them different.  Try doing a surface finish contour with your construction plane tilted ten or twenty degrees from your tool plane.

Well were it can bit you as an example is, if the Cplane is different to the Tplane when programming and you use the features to get depths for example. when you select a feature for the depth it will be wrong due to the location of the Cplane relative to the Tplane.

 

Same thought if you are using Depth controls during Surfacing the values once again are based on the Cplane not the tool plane.

 

Just a thought.

Ahhh interesting. Dunno when i would ever use this...but interesting nonetheless.

I'm pretty sure I've had them different when using geometry not perpendicular to the tool plane to create a toolpath using some geometry from a different plane. Haven't had much need since switching to mcfsw and using the "project to tool plane" feature.

Hmm... that one made me think

Got an example so I can wrap my brain around that?

[Matthew Hajicek - Singularity]

I'll do one as soon as I get a chance.

If I want to tilt the tool I generally create a plane and then that plane is t and c plane, again the same. I'd also be interested in why both.

 

I also have another question that I am going to start a topic for.

[Matthew Hajicek - Singularity]

What I'm talking about doesn't tilt the tool, but it does tilt the waterline stepdown direction.  I used to use it on some runner fans, then switched to Surface Finish Hybrid, and now I use Surface Finish Blend.

I didn't even realize the software would do that. Thank you for teaching me something new about the software.

So, basically it breaks down like this:

 

WCS is your coordinates and work offset

Tool plane is your "direction" of the tool, or the plane that perp to the tool

Comp is an arbitrary plane that can skew your toolpath

 

Does that seem right?

Going off the simple sample file I uploaded...I would say that is a very good description. I too had no idea it could do this. Stupid question answered!

[Jayson Kramer]

WCS, Work Coordinates relative to the world origin and part origin.

 

TPlane , plane in which the tool is cutting in.

 

Cplane , Construction plane that you draw in.

 

All lie together in space or can be individual set for different reasons. example changing the Tplane to tell Mastercam to index to new rotational position . Cplane to change based on drawing part from print and creating a temp datum Cplane based on the view you are working on. making it easier to follow the print Dim.

 

Just a few of my thoughts for you.

If you have anymore stupid question like this one, keep 'em coming! I think quite a few of us learned something new.
