      <description>&lt;P&gt;Facing-op has some useful features for example "Chip-thinning" and "extend before retract"&lt;BR /&gt;Only problem is that they have som quirks depending on how you use them.&lt;BR /&gt;&lt;BR /&gt;Scenario: simple facing where I want to "roll" the cutter into stock and face the whole surface with feedrate F until the whole cutter has passed the stock. To make it a bit more interesting I want to do it in multiple stepdowns with a finishing-pass with different feedrate.&lt;BR /&gt;&lt;BR /&gt;Seems simple? Just set multiple depths with a finishing cut and then check the boxes for chipthinning and "extend before retract"? Nope.&lt;BR /&gt;&lt;BR /&gt;&lt;STRONG&gt;First problem&lt;/STRONG&gt; is that "extend before retract" only prevents the tool from retracting while half of it still is on the part.&lt;BR /&gt;BUT! it do that by just adding a lead-out wich often has different feedrate.&lt;BR /&gt;&lt;BR /&gt;&lt;STRONG&gt;&amp;nbsp;Second problem&lt;/STRONG&gt; seems to be the combination of chipthinning and finishing-feedrate.&amp;nbsp;&lt;BR /&gt;The toolpath starts with a regular lead-in, then arcs/rolls into the material with the set cutting-feedrate.&lt;BR /&gt;BUT! (again) it do the same on the finishing-pass. IE. it starts the cut with cuttingfeedrate and switches to finishing-feedrate at the end of the chipthinning-arc&lt;BR /&gt;&lt;BR /&gt;One solution for #1 is to make sure you have the same lead-out feed as your cutting-feed, witch then becomes the same problem, but opposite, on the finishing-pass&lt;BR /&gt;&lt;BR /&gt;When i tried to just add a pass-extention half my tooldiameter +1mm the chipthinning vanished.. so no solution&lt;BR /&gt;&lt;BR /&gt;The only way to get good surfaces seems to do the finishing-pass as a separate operation&lt;BR /&gt;&lt;BR /&gt;Annoying ...&lt;BR /&gt;&lt;BR /&gt;&lt;BR /&gt;&lt;BR /&gt;&lt;/P&gt;</description>

      <description>&lt;P&gt;I agree with this. While lots of other operations in Fusion allow for a finishing feedrate it doesn't work with Facing. I have ended up doing two operations for my facing on many occasions. One to rough down to 0.2mm off height and a final one to take it to the required height and at a different feedrate.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;It would be nice to combine this into a single operation.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>
