So there is a piece I’m working on. 3/4 inch plywood
80mm x 300 mm rectangle with filleted corners.
5 x 39mm holes 14mm deep in the topside.
3 x 9.3mm holes in the centers of 3 of those larger holes.
If I save the CNC program and use a 1/8 flat nose endmill everything seems fine.
However, if I use a 1/4 endmill. All goes to hell.
With a 1/4 flat nose it cuts through my part to make those 3 smaller holes. And takes
longer to cut the part because its making these extra cuts. What do I do.
I literally pick the 5 larger holes one by one and choose a toolpath depth of 14mm. Toolpath: Hole with pocket strategy.
Then I chose the 3 smaller holes one by one and use a toolpath depth of 19.56mm Toolpath: Hole with pocket strategy.
Then Chose the outside of the part, cut at 19.56mm with three tabs. Toolpath: Part with 3 tabs.
When I add those second holes of 19.56mm depth inside the already 14mm deep pocket, does that 19.56mm start at the work piece topside
or 14mm below the work piece topside?
