Most Mechanical Engineers Misunderstood this simple Feature

In this video, we revisit one of the most debated DFMA suggestions from the previous video- undercut relief at stepped shaft shoulders. Many engineers suggested that a simple chamfer on the mating hole can solve the same problem more easily and economically. So, in this video, we will discuss: • why shaft shoulder fillets are created during machining • why undercut reliefs are used • undercut vs chamfer approach • assembly and manufacturing considerations • and where each method actually makes sense in real engineering ▀ ▀ ▀ Chapters: 00:00 Undercut vs Chamfer fitment 01:09 Common argument 02:07 Assumptions clarity 02:49 Corner radius during turning 04:27 Chamfer method 05:49 Undercut relief Reason 1 08:06 Undercut relief Reason 2 09:55 Undercut relief Reason 3 11:57 Undercut relief Reason 4 12:44 Conclusion ▀ ▀ ▀ #DFMA #mechanicaldesign #Machinedesign #Mechanical #Solidwork #Mechanicalengineering #mastermechanicaldesign
