Fixed the program this morning and got the Haas VF2 up and running again on these vent covers!
I tried something different this time around; when removing the material from the center pocket above the vent grooves, I decided to use the slot clearing method with the 2D pocket toolpath. I haven't used this specific programming method very much in Fusion because of the stress it could cause on the stock and or tool. Slot clearing puts your endmill at 100% tool engagement, which could cause chip clearing issues or too much strain on the material, causing it to vibrate or come out of the vice. To my surprise, it worked out exceptionally well and had the settings just right where I got little vibrations and maximum material removal.
Learned a tip from my boss for when bolting anything on an already finished surface, you can use soft metal washers (such as copper) to place under the steel screw. It allows you to put quite a bit of pressure on the bolt without worrying about marks on your part.
I also got to use the manual programming section in Fusion360 CAM, where you can add special code to your program. I didn't get too deep into it but used a basic machine stop for when I needed to add the bolts to the part. The downside to the programmed stop is that unless you have it positioned in between a tool change the spindle doesn't turn back on after starting the machine up again. I haven't looked into it further and may be a simple explanation for this but I thought it was interesting.
The final deburring and clean up I was able to do with an India stone which works really well with small burrs and perfect for flattening surfaces.
