hello, please, i need your opinion about machining 3 parts almost identical.
For each part i made 3 drawings :
- the upper one is as it is
- the one in the middle is with dimensions
- the bottom one is where i have some isues
- all files share same content
- all parts have in common a o36.5 [ -0.05 .. 0] grove, with it sides required to be at 1.6 rugosity
......- how can i keep this condition while machining many parts ?
......- should i consider 2 tools ?
- all parts have in common a o25.11 [ -0.05 .. 0] outside diameter ( surface A ), which i intend to machine at 1st clamp
......- for 1st part, how can i realize the o26 [ -0.021 ..0 ] inside diameter, with 0.03 concentricity with A ?
............- only the 2nd clamp may input a 0.03 error from "jaw-part-clamping"
......- for 2nd part, how can i realize the o20.015 [ 0 .. +0.021 ] inside diameter, with 0.02 concentricity with A ? 1.6 rugosity ?
......- for 3rd part, how can i realize the o20 [ 0 .. +0.021 ] inside diameter, with 0.04 concentricity with A ? 3.2 rugosity ?
......- i intend to ignore the o20±0.2 gap in between, and machine continuous
......- these holes are pretty close, ~o20 [ 0 .. +0.021 ] x 68, which is not so long, ~3D, but i would like to keep that [ 0 .. +0.021 ] as much as it is possible
kindly !
