internal blind spline relief or cross hole spec for manufacture
I need to spec the relief or cross hole required to allow manufacture of a blind spline.
if my understanding is correct, either I can have the spline cut with EDM in which case no relief is needed, or I go for broaching where a relief below the spline is needed to remove chips and allow the tool to pass.
As the shaft is critical structurally I need to be able to design the relief accurately for use in FEA software.
Can anyone point me toward a standard or similar to define the required relief for a given spline type.
(FYI - spline is a blind internal ANSI B92.1 class 5-44mm nominal diameter-13 teeth-8/16 pitch-42mm deep, shaft is 90mm OD where spline is required)
