bottom fillet

[kal_pesh]

i have to machine pocket dimension is 3.375 wide depth is 1.567 and bottom fillet is 0.250 both side.( length of pocket is 6.0) my boos wont me to use 1.5dia cutter to rough out pockt than i have to use 0.500 ball nose end mill for radius ..my question is haw to live material ( At bottom ) for 0.250 radius?....

Let your boss know, that there is a faster and easier way.
a 1/2" cutter is weaker and will leave cusps along the floor

Tools to use:-
Roughing----Ø1.5" cutter with R0.25" corner Bullmill to rough the slot
( once up the middle, then along the walls ) XY offset=0.010", Z offset=0.010"
Finishing----Ø1.0" cutter with R0.25" corner bullmill to finish the floors, stay away from the walls. Multipasses ON, XY offset=0.020" Z offset=0.0"
Ø1.0" cutter with R0.25" corner bullmill to finish the walls. Multipasses OFF, XY offset=0.0" Z offset=0.0"


Geometry:-
to get wireframe- Xform translate the chained shape using "Join" to Z-6"
to get surfaces - draft the chains in the Z- direction for 6"
to get a solid - extrude the chained shape you have, make the arrow point in the Z- direction, and accept, set distace to 6", and accept

Toolpathing:-
Your WCS and toolplanes should be "Front view"
and the geometry you select for a 2D_Contour will be the top "join" wireframe lines you created.

All up you should only have 3 - 4 operations in total for the slot

I assume you only have access to mill level 1. Using Mill level 1 create your pocket operation and set Z stock to leave at .250 to stay above the radius.

Copy this operation and set z stock to leave at zero and put X-Y stock to leave at .250

You now have the pocket roughed out but left stock for the corner radius of the ball end mill using 2 separate pocketing operations.
