      <description>&lt;P&gt;I have a hobbyist CNC that is just not rigid enough for some of the operations I want to perform.&amp;nbsp; &amp;nbsp;For example, if I am cutting out a part, I'll use a 2D Contour toolpath and with multiple steps to mill to the bottom, setting radial stock-to-leave at about 0.5 mm.&amp;nbsp; I then w run another 2D Contour in a single pass, full depth, with 0 stock-to-leave, as a finishing path.&amp;nbsp;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;If the stock is greater than say 25 mm, I get destructive chatter on the finishing pass.&amp;nbsp; &amp;nbsp;I've played around with speeds and feeds, but haven't hit on a fix.&amp;nbsp; &amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I'm wondering if there is a toolpath option that will allow me to mill a contour wider than the bit.&amp;nbsp; I remember I saw something like that once, where the bit described a small spiral as it moved around a contour, but I can't remember the setup.&amp;nbsp; &amp;nbsp;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Any thoughts?&amp;nbsp; Thanks!&lt;/P&gt;</description>

      <description>&lt;P&gt;You can still finish pass with Depths enabled, I recommend 1x tool Dia for now, and play around with 2-3x. You can do repeat finish pass if youre REALLY worried about the "Stepped" look you may get with your tool deflection.&amp;nbsp;&lt;/P&gt;</description>

I know that in theory it should be Conventional but might be worth a try.&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;&lt;STRONG&gt;I can see that the internal Radius prior to where the chunk is ripped out is also not good which could indicate that the flutes are getting clogged by the time it gets to that point and worse by the last Radius.&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;STRONG&gt;Just a thought &lt;img class="lia-deferred-image lia-image-emoji" src="https://forums.autodesk.com/html/@D5D66E11BC96A1C8427F98151D3E9A7A/emoticons/1f642.png" alt=":slightly_smiling_face:" title=":slightly_smiling_face:" /&gt;&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;I've never milled in wood, but I'm kinda surprised that doesn't happen all the time, if your tool is anything but supersharp. At the first radius, with conventional, you're just "pulling" in the grain direction, but at the other two,&lt;/P&gt;&lt;P&gt;you're basically ripping the wood out of the stock. A change to climb milling wouldn't change that fact (?), or maybe some wood milling wizard could chime in here? I know there's a lot of you out there. &lt;img class="lia-deferred-image lia-image-emoji" src="https://forums.autodesk.com/html/@D5D66E11BC96A1C8427F98151D3E9A7A/emoticons/1f642.png" alt=":slightly_smiling_face:" title=":slightly_smiling_face:" /&gt;&lt;/P&gt;&lt;P&gt;/David&lt;/P&gt;</description>

      <description>&lt;P&gt;Thanks for all the responses!&amp;nbsp;&amp;nbsp; I will do a little more playing around with climb vs conventional milling.&amp;nbsp; My guess is I'll have to do what programming2C78B suggested and take the finishing path in multiple steps also. &amp;nbsp;&amp;nbsp;The finish won't be as good, but that's what sandpaper is for.&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; Thanks!&lt;/P&gt;</description>
