If the process locates the dropout in one axis with great precision, it should also have similar precision in other axes. Especially when we are talking about thermosetting resins.
But the fork is not just a homogeneous mass of thermoset, it contains fibers in a selected set of orientations, which brings its own set of internal stresses and strains. I don''t have experience as a molding or composite engineer and certainly of nothing related to cycles, but I have been a systems/safety engineer on projects that include such materials. Thie means I need to review and consider all discrepancies to see if the problem challenges any product safety requirements or statutory/regulatory requirements. Very surprising discrepancies occur in initially quaified manufacturing processes. And I appreciate how expensive it can be to capture all the deviant parts before they are released to the next level of system assembly.
