New to Fusion 360 and CNC. Have a lot of plunges to do rounded corners with 2D Contour, can this be fixed?

[Anonymous]

I'm very new to Fusion 360 and to CNC milling. I have created my first toolpaths and managed to get it to work on my machine, but I have some rounded corners and they take a very long time to make as fusion 360 makes it go around these corners my plunging down repeatedly  100s of times. This makes a simple cut take a very long time to perform and I feel like it should be a very easy cut so there must be some setting I have not done correctly. I, however, can't seem to figure out what this setting is. Can anyone give me some hints?

I think this is how I can share my workpiece, if not please correct me in that too 🙂

File that your link points to is not correct one, go to File, Export, save your project file in F3d format to desktop, come back to forum and attach that file to next post.

Ahh sorry about, must have linked the wrong file. This one should be the right one

In your first operation you selected top and bottom contour, only need bottom selected.

You may also wanna use triangular tabs instead of rectangular.

Rectangular tabs cause indentations of tool on each side of tab while tool travels up and down in Z axis and loses load of a cut in X and Y axis.

With triangular tabs, tool changes direction in Z axis at top of each tab but it doesn't stop moving in X and Y direction so it keeps constant load and indentation are avoided.

Thank you very much for that, I'll try those suggestions out. Also thank you for the tip on the taps, I did notice those indentations but thought that was an issue for later. Now I can fix that too 🙂
