    Involute Spline

    01. Dei max and Die min, ISO 4156, are calculated for Tolerance Class 7, regardless of Spline Tolerance Class. Why is this and how is correct ? In one of their Example, they have an Internal Spline Class 5H but Dei max is calculated for 7 class. 02. Involute(X) = 0.03565158 What Formula is used...

    Relation - Internal Clearance to Press Fit

    Having a Bearing like 35 x 62 x 14 with internal clearance about 0.012 how can I make a relation to Press Fit TOLERANCE on ID How much press fit is too much ? to kill the internal clearance ... That is not my goal at all but the press fit can be calculate with relation to internal clearance ?

    NX5 - Reattached and/or Reposition - HOLE

    It is a pre NX5 hole ! Somewhere I lost an associativity, I believe. Any feture an want to edit, blow the whoole model. I am in process of hunting all the features but one hole can not be repositioned (or I can not update it)
