Do you remember when you started machining? Bet you started with an end mill and fly cutters scared you to death. By now, you've got that all behind you. But, as you gained experience, did you learn how to get the most out of what you have in the shop? For 2019, why not grab that slitting saw arbor and blade and start to look at them differently.
Here's a novel idea. Cut a part off and hand finish it. While a hand finish isn't the equal to the finish from a fly cutter, it is an alternative. So, on your 3 axis mill, take your slitting saw and cut the piece off. Now, it's much easier to get to the underside. So, finish it by hand. This is a great alternative if you find yourself machining a very thin part or working on a piece that seems impossible to hold. Just cut it off and hand finish it. You'll discover that you save time by hand finishing the piece. That's because if you keep destroying the part by machine finishing it you just waste time. Every time to start from the beginning is a waste of time, money and material. Cut waste in 2019.
Resolve to give your parts a bit of relief in 2019. That doesn't mean they need time off. But it does mean that if you don't want them to break, you must give them a break in the form of a relief slot.
A relief slot provides just enough give to clamp around tightly and not destroy the integrity of the part.
Just use your slitting saw. It is the perfect tool for creating that relief slot. The slitting saw arbor holds the blade firmly in place and in just a couple of passes you'll have that slot. Be sure to pick a slitting saw arbor with a deep cap and low profile to get you as close as possible.
