2d Pocket Operation

Hi,

I am creating a 2d pocket operation for my setups and the toolpath being generated doesn't seem to clear the whole pocket face selected. I want to treat, both open and closed pockets, with the same method removing all of the pocket face without leaving any stock. The problem I'm facing here is that the tool's entry point is the very left (or right) edge of the pocket face (which is right), BUT I WANT THE TOOL'S CENTER TO BE PLACED ON THE EDGE, IN ORDER TO START THERE, AND NOT INSIDE OF THE POCKET.

So let's say I have recognized a pocket in my part where it's length (on the x axis) is equal to 684 mm starting from 0 to 684. The tool I'm using for the operation has 3 mm diameter, so the entry point of it (the center of the tool) is now 1.5 mm (on the x axis), and I want it to be 0 mm, so the center is placed on the very left edge of the pocket, and the remaining 1.5 mm will be outside from the pocket (on the left) and inside of the pocket (on the right). That way the pocket is being cleared the proper way, without leaving any uncut material. I want to treat the closed pocket (see jpg attached) the same way, meaning I want to trim 1.5mm (with 3 mm tool) of the part (OUTSIDE OF THE POCKET) both on the left and right side of the pocket.

I have tried using the "stock to leave" option, but when setting the radial stock to leave equal to -1.499 (approximately equal to the tool radius), it removes stock both on the x axis (where I want) and on the y axis (where I do not want), cause the geometry I chose is the pocket face.

I have thought of creating to sketch lines parallel to the pocket height and placed 1.5 mm left to the starting edge of the pocket and 1.5 mm right to the last edge of it, but that will take quite a computational time and I would like to avoid it.

Thank you in advance.

Would you be able to share your Fusion file here or privately?
File > Export > Save to local folder, return to thread and attach the .f3d file in your reply. To share the file privately, it's the same process, but email it to me: seth DOT madore AT autodesk DOT com

Hmm. That file isn't opening for me, could you export and share again?

In the method above, it's going to extend the toolpath out to the stock contour. If you want to reduce that amount (due to machine travel), you can turn on Stock Contours and select the part profile. This will scoot in the toolpath a small amount:

Hi seth, thank you for your response.

I'll try that asap.

Can I follow the same steps for a closed pocket as well (see attached image)?

Thank you!

You want to intentionally violate the end walls?

Hi Seth, yes I want to do that.

Press the ALT key and select one side of the slot. Turn on Stock Contours and you'll get this:

Hi Seth, I want to thank you for both your answers and the time spent on my problem from your side.

I have tried your suggestions for open and closed pocket examples, achieving a better result compared to mine, but still there is something that needs to be resolved. I was wishing if you could help me here as well, that's why I'm attaching two jpeg files containing both the tool entry point achieved now(wrong), and the desired one(right).

I want the tool center to be aligned with the outer vertical edge of my pocket, and not tool_radius (mm) away from it.

This needs to be accomplished both for open and closed pockets.

Thank you in advance!

And you want to plunge and retract as shown in the "rightWay.jpg" image, yes?
Can you share a file that you're working on?

Yes Seth, this is what I want to achieve.

The file I'm working on remains the same.

Thank you again!
