Does Fusion 360 not simulate pecking accurately?

[davef_dci]

Hey folks,  Quick question. I'm using Manufacturing to produce a turned part so it's my first opportunity to use a lathe driven by Fusion.  I'm drilling a bit of a deep hole and would like to peck drill it using chip breaking partial retrack . However no mattery what adjustments i make to the pecking depth, the simulation is showing the part being drilled in three steps.  When it shows the tool path before simulation starts it does show a "dashed" line that looks like they're at the right steps but this doesn't show up when I simulate. 

Does Fusion not visually simulate the full peck? 

Also - sorry - how do I attach a Fusion file to this post?

THanks!

Sometimes if the retract of the Peck is small you may need to slow the simulation down a lot in order to see the moves more easily.

Thanks!  File attached. The operation in question is the first operation in Setup 7 which should be chip breaking in 5mm increments. As mentioned the toolpath shows "dots" at what appears to be every 5mm, but the simulation shows the operation being done in three pecking steps (that look like they're closer to 20mm) regardless of what I'm setting the peck parameters at..

Oh, it's certainly pecking. Turn on "Show Points" in the Simulation toolpath display, and you will see this:

Furthermore, if you slow your Simulation way down, you will see it stop and retract at each of those points:

And in regards to the full retract out of the hole (if that's not desired), just increase your Accumulated Pecking Depth to a value that's equal to the depth of the hole (or greater)

Got it!  I didn't realize that if the simulation was running above a certain speed you would not be able to see the peck but that makes sense now
