Making Titan's T-1M. I'm using a destiny 3/8 rougher and 3/8 finisher. Roughing op is great for the walls, pocket. I switch to a pocking operation going full depth of 0.5". In the roughing op I leave 0.005 axial and radial.
Speed of both cutters are 4k, 0.0025 ipt, 30ipm.
In the pocket operation I have the endmill just plunge down at 10ipm and start hogging out material. Everything is fine, however when the tool does OD of the pocket walls, it's also doing the floor. I'm think deflection is causing the center area of the pocket to be more proud than the OD of the pocket.
Am I crazy to think Tormach 1100 should be able to do this? Plunge down to floor, finish the floor and then when going to the OD of pocket doing the wall and floor at the same time? Hope this makes sense.
The red lines are the areas where the little "island" is more proud than the finishing tool path for the OD of the pocket.
