I have attached an example of the path the cutter takes. The line that is at an angle ends up machining a little deeper. It is a common path of travel during the machining process which I...

Wen cutting a pocket that has multiple bosses and things that have to be machined around, the toolpath generated uses a common path of travel to reach all areas of the pocket. At these locations the...

I finally determined what the problem was...eroded tool probe. My Renishaw tool probe had actually eroded away or actually developed a dent/crater in the middle of it. The dent was so small I...

I see what your saying with the shade settings, that makes sense. Do you have any ideas why the part would come out the way it did in the initial post? You can see from the molded parts that the...

How did you convert the solid to surfaces? I guess I dont know how to do that.

I have not tried that, I will try that on the next part I make and see if it fixes my problems. It may just be the way the designers are creating the surfaces in solidworks. Thank you for your...

Here is the problem toolpath. Its machining fine on the sides but 0.002" deep in the bottom of the cavity.

Here is the toolpath shown in solid and wireframe. Since this is a surface toolpath operation Mastercam shouldnt machine any deeper than the surface right?

I am running Mastercam X3. I will post some screen shots of the toolpaths so you can see what Im talking about.

I am machining some silicone molds and when I generate the toolpaths, the toolpath shows that it is under the surface. You can only see it if you turn the part to wireframe. However it only does...

Thank you Superman that makes sense. I am machining a similar cavity tonight and will see how it works out.

Ok ill post the file so you can see the parameters.

Ill also try the check surface idea and see if that works.

I think using center containment, as the ballnose runs up the side and centers the...

Actually, no I didnt use check surfaces. I was thinking about a different setting. Are you thinking if I set the outside of the channel as a check surface it wont do it?

Yeah I did use check surfaces. Im not at my shop but will be later. Ill generate the code and post it.

When you use surfacing operations, do you use center containment or inside? Also if you...

So here are some drawings to explain whats happening. The "Shape" pic is what I need to machine and the "Machined" pic is what is getting machined. The chamfer is only about 0.001"-0.002" so the...

WallyL7,
I work the evenings and didnt have a chance yet to follow up with you. I will be generating the nc code tonight and will try to post some pics and stuff of what im talking about.

I am trying to mill a radiused channel. It has a radius of 0.118". Essentially all I want to do is run a ball end mill across my part to make an o ring groove. The problem is the radius is not a...

The other thing to try is making sure the tolerance is set low enough. Default is usually around 0.001. Its the box right above the max stepdown setting in the contour toolpath menu. Make sure its...

Try these guys.
