The problem is, i need a large pocket 36cm x36cm 6mm depth to clear.
I made some nice cuts with the maslow presision and accuracy is ok.
The wood starts curling up when parallel cuts ar perpendicular to the grain of the wood, the curl gets bigger and bigger. what makes that the boards start flying of the top and the depth is not correct anymore.
Wood: 18mm Birch plywood
Bit: 8mm flat fluit, 4 cutting edges
Spindel speed: 10k tried 14k to fix it but thats to fast and hot.
CAD: Fusion 360
Tried pocket at passes of 3mm
Tried pocket 1 one pass
The problem is it builds.
I’m going to trie a pocket operation with a toolpath parallel to the grain in a zig zag motion.
Added one picture of a good cut. to illustrate everything works. It’s the first cut thats not ok, not due to user error
Any hints are welcome
